After the slot racing boom followed by the crash of the late 1960s, "Champion of Chamblee" remained the world's largest pro-racing oriented slot car company. It then lasted under 3 different ownerships, eventually purchased by Parma in 2008.

Originally based in a suburb of Atlanta, Georgia and headed by investor, banker and slot car enthusiast Jim Williams, it began its operations in early 1964. By 1967 Champion had become one of two "motor kings" in slot racing, the other being Mura, a smaller company based in San Leandro, California. From 1967 on, the two companies fought a battle for supremacy that lasted until Champion collapsed as a major motor supplier in the late 1970s. By that time, the Mura hardware was outperforming the products from Chamblee.
But before that fate, Champion proved a formidable force in both performance and marketing, virtually dominating the market in the South and East Coast of the United States as well as in the United Kingdom.

Champion began its product line with an aluminum sidewinder chassis for the "big" Mabuchi FT36 motors. This chassis was sturdy and reliable compared with other period hardware. Shortly after, they introduced a line of silicone tires and wheels with a "Tru-Lok" collet-style assembly similar to those found in the K&B "Series 2" kits, using the stronger straight axles. They followed this by acquiring the leftover Mabuchi FT36D and FT16D motor supply from several bankrupt "wannabe" slot racing manufacturers, such as Hawk and Renwall. Champion will follow that practice for several years, acquiring leftover inventories as other companies folded.
 

The "700" series motors

 

Champion introduced the "701", a "hand selected" FT36D (can-side drive) in late 1964. Dark silver with a white stock end bell, it retained its stock armature, shod with # 30 AWG brown wire. The "lesser" ones were taken apart and the armature rewound with #29 AWG red wire and dynamically balanced by grinding large chunks off the laminations! They were called "702". Few of the "red-wire" motors were built as they were quickly replaced by a new version using a dark red brownish wire. Sometimes, the rewound motors were fitted with two self-tapping screws as the cans retaining tabs easily broke.

 

 

The next step was the "703", rewound with # 28AWG wire and using new full-coverage nylon insulators, then dynamically balanced. The 702 and 703 used the stock Mabuchi motor bearings, but the 703BB (ball-bearing) was also available with a small flanged, un-caged ball bearing on the outer part of the original large brass bearing housing on the motor�s can.
This later was replaced by a large high quality flanged and properly caged ball bearing. Later, both 702 and 703 could be purchased as "PB" (plain bearing) or "BB" versions. These gave way to the "704", "705" and "706", evolutions of the "703" with less and less turns of larger and larger gauge wire. This led to the "707", with rewound arm, new "ARCO" magnets and one-piece magnet shim. The armature, as in the 703 thru 706 motors, received clever nylon insulators encaging the whole stack, a large high quality commutator and # 27 brown wire. Some 707 received the ultimate evolution, a Champion-made Celcon end bell with a small un-caged ball bearing, pent-roof brush holders and plenty of air circulation. Called the 707BB, this upgrade had also been available earlier on the 702BB, 703BB, 704BB and 705BB.  Most 7-series motors are dark silver, but there were green ones which used the old Renwall and Premier leftover cans, and the metal foil labels vary in color from gold to silver with black or blue markings, some with red accents. Some are quite rare today. All used the stock Mabuchi red and green vinyl clad lead wires and all were sold in a Champion plastic tube with a vinyl cap. Left, 701 and two 702s in silver and green.

 

 

A sealed Champion 703 armature showing its full-coverage nylon insulators, the letters A-B-C written with a felt pen over the poles for balancing purposes. The stacks were ground as needed, a pretty barbaric system, but it worked. Note the large commutator, the very best in the business even by today's standards.

 

 

 

A scarce dark green "704BB". This motor has a ball bearing only on the can side like most of the "BB" series except for the scarce ones fitted with the Celcon air-cooled end bell. This motor is not fitted with the ARCO magnets, as only the "707" was equipped with the stronger shimmed magnets. This mint example was kept by Champion's president and owner, Robert Rule, for over 35 years. Note the packaging, a printed plastic tube with a vinyl cap.

 

 

The now scarce "705" was offered in the 1965 and 1967 catalogues and can be seen at the right on this picture, using a green-color car from the old Renwall inventory. It is fitted with a can screw on top and bottom, indicating broken tabs during re-assembly with the hot armature. This was indeed, a Champion modification. Later motors used pin tabs similar to Mura's and many other re-winders.

 

Another scarce Champion 700-series motor is the "706". They also existed as a ball-bearing version and were the last iteration before the definitive and more common 707. However, this particular example is a fake, part of what is possibly the largest forgery ever perpetrated in the world of vintage slot car collecting. More will be soon revealed about this truly extraordinary fraud attempt. The "706" armature and packaging shown here are also part of the soon to be revealed forgery by a prominent person in the world of vintage slot car racing.

   

 

 

 

Examples of different metal foil labels on 700-series motors. There are at least 4 generations of graphics, the dual-color red and blue being the rarest. The metal foil colors ranged from chrome to gold to red. The blue "702" is part of the forgeries mentioned above, made of standard Mabuchi components and sold as "Champion" motors.

 

The 707 and 707BB were fitted with the ARCO magnets and had a one-piece steel shim visible on the pictures at right. Some late production units had nickel plated brass spring posts and the cans were attached to the end bell with pin tabs (see picture at right). The "707" was very successful in winning endurance races through the United States and was a true powerhouse. Torque was truly impressive even by today�s standards, and brakes were greatly improved. The motor at left has the improved Celcon air cooled endbell with pent-roof brush holders.

 

A "707BB" with the later caged bearing, air-cooled end bell and pent-roof brush holders, next to  is a standard plain-bearing "707". ALL genuine 707s had a metal-foil Champion sticker, but Champion sold kits which did not have such a sticker and included all the parts of the regular 707 except for the special and powerful armature. Below, comparison between the Champion Celcon air-cooled end bell (left) fitted with a tiny ball bearing or a bronze bushing, with specific pent-roof brush holders, and a stock Mabuchi end bell used on all non "BB" versions of the Champion 701 to 707 line.

It is obvious that the pent-roof brush holders greatly helped cooling. In subsequent models, the pent-roof brush holders were soldered to the brush housings.

 

Champion first RTR sidewinder RTR cars & kits
 

The first Champion chassis was an alloy pressing with a loose drop arm affixed by an aluminum pin retained by a steel clip. It was fully adjustable and the oval-shape reversible oilite bearings allowed one to fit smaller or larger rear wheels. The motor was solidly held by an extra bolt-on plate around the large Mabuchi brass bearing housing.

 

 

The very first kit box with a later corrected price of $3.98.

 

 

The CP-101 Lola GT, Champion's very first RTR, in its original box. The paper insert inside the body received an injection molded 2-piece driver copied from the popular Cox unit.

While it was obviously inspired by the original Classic/ BZ frame, it was much stronger and used bolts and nuts instead of self-tapping screws except for the body mounts, but even this could easily be changed. This picture shows an assembled unit.

 

After the first Champion chassis was issued in mid-1964, the first Champion RTR car was produced from early 1965, using a Lancer supplied Lola-Chevy body. Champion had a nifty printed card interior on which a copy of the Cox famous "La Cucaracha" driver, molded in translucent nylon and generally painted in silver and black was glued.

In spite of its bulk, the car handled quite well thanks to the rugged sidewinder aluminum chassis design and excellent silicone or foam tires on Tru-Lok taper lock wheels.

 

The strong chassis first housed a Champion 701 stock motor, but over a period of 3 years in which the car was produced, the motor options changed as the company was offering hotter and hotter version of the big Mabuchi. The last versions had full-race 707BB motors with air-cooled end bell, ball bearings at both ends and ARCO magnets.

Several bodies were offered, from the Lancer or Pactra Lola to the ex-Unique Ford GT, a Mako Shark, McLaren-Elva, Chaparral 2D, Ford X1, Lola T70 and a Dodge Charger. The wheelbase extended from 3-3/4" to 4.5" by moving the front axle location.

 

Champion wanted to prove the speed and endurance of their cars and motors. In 1966, at the famed Santa Ana Raceway in California run by enthusiast and master modeler John Hale, two of these Lola GT and a Ford GT fitted with the same running gear successfully ran an actual 1200 miles of racing in 80 hours, including all stops for regular maintenance. The tires lasted the distance, and only a few sets of braided contacts were changed. When the motors were disassembled, they showed virtually no wear except for normal motor brush wear. Photos of these cars and the story of the record can be seen in period magazines and local newspapers, and one of the Lola cars is shown in the 1967 Champion catalogue. This record has never been bettered. At least two of the cars, a Lola and a Ford GT, survived.

At least two of the cars, a Lola and a Ford GT, survived. They were kindly supplied to the LASCM by Champion's former owner and president, Carl Ford. Today, this record remains unbeaten and there are no challengers. It would be indeed fascinating to see if modern machinery could outlast the old machines on the same set of tires and motor brushes.

The two known survivors as found show serious body damage but are still operative and in good running condition. The track was an oval on which braking sections had been taped to allow controller-less operation, so that the cars could run day and night without the help of an attendant. The fate of the third car is unknown after it posed for the catalogue's picture.

 

A page of the 1967 catalogue showing the "missing" car, bearing a # 3 on its roof. The whereabouts of this car are unknown at this time. Note the destroyed body, meaning that the running may not have been smooth sailing. The same evidence of hard impact are visible on car # 1 seen above.

 

A near-new CP-105 Ford GT RTR shows the printed paper interior used on all the early cars. There were 3 different versions of these interiors, printed on beige or blue card. Note the huge "silicone" (in fact, molded natural rubber) tires over Tru-Lok wheels and the silver details hand painted from the inside of body prior to spray painting. As clearly visible on this example, the sprayed orange color is bleeding into the brushed silver on the headlights covers.

This series one RTR box with the Ford GT roadster has no stock number printed on it. The stock number was hand written on the small oval inside the round sticker. Note the "707" blue foil sticker at left, meaning that the price was not the same as that of the basic kit.

 

 

In 1967, Champion issued their first model using the new Mabuchi FT16 motor.

The model used a Champion-painted Lancer Porsche body, with reinforcing side tape on its sides, in red or blue color.

The motor was the "601" shoehorned into the same old  frame designed for the larger "700" series and the wheels were drilled for lightness and cosmetic purposes. However the drilling was very imprecise and the wheels look like drilled by an amateur.

Champion early catalogues
 

 

the 1965 and 1967 catalogues, later published with a 1968 added insert, Numerous flyers and a newsletter were later published until the early 1980s. The 1966 catalogue is especially scarce, as it consisted of color printed pages bound by a blue plastic tie.

 

The "500" series motors
 

Meanwhile, Champion was also working with the smaller Mabuchi motor, as the racers preferred its lighter weight. The leftover, hand-selected dark blue ex-Hawk Mabuchi FT16D Can-driven motors were re-christened "501". Most were blue in color as they used the old Hawk leftover cans, but when Revell packed up, Champion purchased the stock of unused SP80 motors and tagged them with the aluminum-foil sticker. None of these silver motors was ever used for rewind duty.

 

 

The first evolution was the "502" with a rewound armature retaining the stock commutator, using a red # 31 wire. Using a set of nylon insulators, a Kirkwood commutator and ground-balanced, it became the "503".

With magnets made from broken Arco 33 from the big 36D and rewound with # 30 red, then rather quickly, reddish-brown wire, it became the "507". So far no "504", "505" or "506" have surfaced, and it is almost certain that Champion simply went from the "503" directly to the "507" to meet the marketing needs of selling these motors side by side with the "707". This is also true of the later "600" series.

 

 

An early and rather scarce  "507" motor with red wire. The can had its tabs nearly broken by a Champion employee as it was opened, so it got the "drill" treatment and received two self-tapping screws to hold things together. Often this resulted in poor end bell alignment and more mechanical disasters upon use.

 

An early "507" armature from the motor shown above clearly showing the balancing method by grinding the laminations stack. Also note the use of a Tradeship commutator, later to be replaced by a Kirkwood unit.

 

 

The infamous "broken" ARCO magnets as installed in a "507" can, showing how precarious the fitment was as far as maintaining a proper gap between armature and magnets. Here, one can see that the retaining U-spring has moved under the left-side magnet, making a close armature gap fitment impossible.

 

 

Three "500" series motors, an early stock can side-drive 501 leftover from the Hawk inventory, a scarce 503 and an end bell-side driven 507 all using the standard Mabuchi FT6D can and end bell.

All these motors received a metal-foil sticker with their names printed in black on silver background. These metal-foil stickers are virtually impossible to remove, so if you encounter a "Champion" motor without it, it is probably not a genuine factory-assembled item since the Champion motor kits did not have this metal foil sticker. The 507 motors had a very short life due to their stock Mabuchi end bell which melted rapidly as the motor reached its operating temperature.

 

The Delrin plastic just could not hold this temperature and reached a semi-liquid state, the brush springs cutting their way into the melting posts with the catastrophic results one can imagine. The "507' was commercially very successful, but was quite unreliable as most of the early rewinds built from the original Mabuchi FT16 or FT16D cans and endbells. The endbell was fitting rather loosely inside the can, itself rather flimsy and easily deformed.  The gimball bearing wore its housing rather easily, causing havoc. The endbell was made of Delrin, a plastic that melted at rather low temperatures, and as the motors got hot from their very basic nature of being not too far from a direct short, the brush holders began shifting in the melting plastic, causing the brushes to arc, cause more heat and eventually destroy the commutator in an acrid smell and white smoke.

 

 


 For this reason, this  motor was later replaced by an upgraded and greatly improved version, the "507-R".
Champion realized that better components were needed, and began making their own endbell from Celcon in 1966. At the same time and after issuing a series of motors using the old Mabuchi FT16 leftover cans fitted with the small Revell/Russkit type blind bushing, they purchased a quantity of modified FT16D can from Mabuchi that used a smaller sintered bronze oilite bushing. These cans were nickel plated and drilled for the fitment of two miniature flat-head slotted screws to hold the endbell in place.
The ARCO magnets were improved, now molded in a more accurate shape and held within a new one-piece shim.

 

 

The "503" is a very scarce motor that was produced for a very short time, possibly only weeks. Both "502" and "503" appear to be the last issues before the "507". May be some day, examples of a "504", "505" and "506" will show up but we are not betting the farm on this.

 

 

At right, two "507-R" motors setups, the early type with the small blind bushing on the right. The 507R were seldom sold separately and were mostly used in Champion RTR cars, but complete motor kits and parts were widely available. This picture shows two of three types of can bearings used. Second-series "507R" were stock Mabuchi FT16D cans with the large brass bearing housing, that were stripped of paint, then nickel plated. But the gimball bearing inside the large housing was replaced by a FT26-style ball bearing held by a Champion-built nylon holder, also sold separately. The 507-R were the first to receive a white paper sticker printed with black ink instead of the previous and more costly metal-foil type.

 

Second-series "507-R" motor using a Mabuchi FT16D can. Probably a case of using any and all remaining parts available, something Champion did with a vengeance.
Champion made their own end bell with better Celcon plastic, a pair of cooling holes and a better, larger bronze bushing than found on the original Mabuchi endell. Nickel-plated brass items replaced the Mabuchi stock brush holders, with pent-roof holders for better contact and heat dissipation. The armatures were of the last "507" type, with nylon insulators and still ground balanced. Most of the "507" and all the "507-R" were endbell-side drive. Champion issued very pretty ready-to-race cars using this very powerful motor, fitted in a beautiful nickel plated brass rod frame.

Champion sold most of their parts separately or in kits packed over a card with a clear plastic blister heat-formed directly over the parts. These two "507-R" kits show two different cards and parts layout, but are basically the same kits. Note that the earlier can (at right) can is already fitted with the magnets and the armature stack with the insulators and commutator, while the later let you do this task as well as fitting the arm with insulators and commutator. How can you tell the later kit? The magnet shim is nickel plated in black, a sure sign of things to come as later 517 and 525 were eventually equipped with black shims never seen on earlier motors. A bit of detective work and deduction is often needed to figure things out.

When the "507" series production began, the motor rapidly became the choice of most East Coast and southern pros, led by Champion Team captain Jack Lane and team members Bob Cozine, Ray Gardner and Bill Thirlwell. Using hand-built, in-line brass rod chassis designed by Bob Cozine and Russkit Lotus 40 bodies, they pretty much cleaned up the Eastern and Southern pro races and rendered this motor and its subsequent evolutions the most popular for a long period lasting until the mid 1970s. Champion produced replicas of such chassis, first with parallel then tapered rail design, as Cozine was evolving his design. Very few of the dark blue 507�s survive today, as they were used, and used-up. Most ended in a trail of smoke after the end bell gave up the ghost

 

 

Last of the Champion-marketed Mabuchi "16D" was this FT16BB twin-shaft model issued in 1967. Named the "5001", it was sold separately and in Champion car kits and some RTRs. It was by far, the best of any stock Mabuchi FT16 ever issued. The can served as a basis for the first few "517" before Champion had their own chrome-plated can in production. At $3.50, it was a bargain. It was also available in black in 1969 and can be found in many period Champion RTR cars.

 

 

 

Champion's second-generation RTR cars

 

Champion's first new chassis since the stamped sidewinder frame was this beautiful open-wheel unit, built in Japan from brass tubing, piano wire and brass rod.

 

 

 It was available only for the new "medium" Mabuchi (FT26 end bell-drive) and for the FT16, and as most pro racers had been doing, attached to the chassis by the two fastening holes on their endbell. A novel feature from pro-racing was the adoption of simple brass tubing as bearing surface for the rear axle. Russkit had shown the way and the Champion motor mount was directly inspired by the Mike Morrissey-designed Russkit motor bracket. This chassis was used in many variations including a widened version for sports cars. Catalogue # 270 (FT16) or 271 (FT26).

 

 

This 1966 Champion Ferrari 3-liter F1 RTR model was issued in 1967 and used a Pactra body and part of the decals that adorned the Pactra "American Red Ball Spl" Lola T90 model. It featured the #270 chassis fitted with the "507-R" motor, sponge tires on Tru-Lok wheels, a Champion-Williams crown gear and O-ring front wheels.

The Harrison RTR was fitted with a Champion "601" motor, with an option of a rewound  "607" for the wealthier customers. Other bodies on such chassis became available in 1968, including the Russkit Honda F1. But other bodies were also used, some from Du-Bro, Pactra, Lancer...

 

Champion's second-generation kits

 

 

In 1967, Champion issued all new kits in this second series kit box. One could get these kits with clear or painted body and several types of chassis were used. .

 

 

Second-series kit featuring a Revell Ford GT roadster body and the aluminum die-cast Snuggler MK1 chassis and a Champion "601" motor. Note the brass body mounts, not as common as the aluminum units.

 

 

Another second-series kit of a Honda F1 with Champion "601" motor and the pretty nickel plated wire chassis. Note the sports car body mounts supplied with the kit in case the customer decides that 3-liter F1 cars are not his thing. The body is a clear-plastic Russkit unit, painted by Champion.

 

Champion needed a less expensive frame line to sell lower-cost, easier to assemble kits to the now dwindling market. The "Snuggler MK1" and "Snuggler MK2" were introduced in mid-1966. The CP-280 (16D) or 281 (26D) Snuggler MK1 featured a Dynamic inspired aluminum die cast frame on which a stamped alloy guide tongue could be bolted. Aluminum or brass stamped body mounts were then bolted on the motor mount.

 

 

Some versions had an independent front axle setup, others had an "iso-fulcrum" arrangement in which a nickel plated wire brace was actuated from the rear axle and held the front wheels. On this picture, such a setup is shown on top.
The CP-245 (16D) 255 (26D) and 265 (36D) MKII version shown below features the same front wheel "iso" mount but the frame itself is a 3-piece all stamped sheet-aluminum design on which the motor becomes stressed. The motor mount bolts onto the end bell while the drop arm bracket is attached to the back of the motor can. The problem is that the weak tabs holding the can to the endbell were to say the least, overstressed, causing the motor to open itself during operation. By the time these were issued, Champion was using genuine, and very popular with the pro racers, Cox "quick-change" guides. A series of RTR cars and kits were issued with both types of frames, the first (cat. # 132) using the hot 507 motor and sports car bodies. By 1968, the "700" motor line was abandoned, and Champion sold their remaining inventories of the big Mabuchi motors in low-cost kits and RTRs until the early 1970s, all these equipped with low-cost "Snuggler MK2"-style chassis.


"600" series motors

 

The new "600" line (the Mabuchi FT26 "medium" size motor as marketed by Champion) sprouted in early 1967. The all nickel-plated, Mabuchi FT26-based line started with the "601" set as the "selected" stock motor. The "607" became the rewound unit with ARCO magnets. Both these "26D" motors had Mabuchi-built cans with 2 holes stamped out on the end bell side and two more above and below the can bearing for a future assembly screw arrangement to help out when the can tabs broke.
A second version of the "601" and "607" can was rapidly issued, featuring only one vent hole.

 

Various "600" series cans. From right counter clockwise, the stock nickel-plated Champion 601 can with extra mounting holes, the second series with only one cooling hole, the other side left shut to improve the magnetic field. The early 617 can with alloy-caged brass bushing and the later version with 525-style bushing.

By the middle of 1966, and under the pressure placed by its racers/employees like Bob Cozine, Champion was preparing its little "revolution", all new American-made cans for their Celcon endbells. The first were sold only as complete motors, the "517' and "617".
 

 

 

A new "607" still sealed in its original packaging, assembled with with two large self-tapping screws. This was due to broken tabs of course. Mura's method of assembly with pin tabs was definitely a bit tidier.

The "607" used a one-hole Mabuchi can, the Champion Cycolac endbell, chrome plated spring-post sleeves (introduced shortly before by Dyna-Rewind) and stronger springs. The ARCO 33 magnets were held by a single spring inside a one-piece shunt.

 

 

 

"600" series armatures: top, the original ground-balanced 607 sold separately.
Below this is a "617" (the first Champion armatures with drill balancing) and below is a "Group-16", an unsuccessful attempt by Champion to run a FT26-sized class to get rid of the obsolete motors. They sold anyway as many enthusiasts fondly remembered their excellent performance and used them up over the years in various vintage cars.

 

  More "600" series armatures, these from 1969 to 1971. At left is a "617" armature, while the "Group 16" at right is a milder version. The three armatures below are all "617" in different winds.

 

The Jail-Door chassis

 

 

By mid 1967, Champion had issued inline chassis directly derived from the actual chassis raced by the famed Champion team. Four models were issued featuring the same basic design: two with 3-3/4" wheelbase, two with 4.5" wheelbase, all for the Mabuchi FT16 and FT26 (end bell-drive) motors. These chassis were manufactured in Japan and were very successful sellers.  This one is the "stocker" for FT26 motors.

Some of these chassis were used to market complete kits, especially for a Ford Galaxie model that is especially hard to find today.

 

A second generation of sports car frames became available by late 1967, following the technical progress accomplished by the pro racers. Again, this frame was available in two wheelbases and two types of motor mounts for FT16 and FT26 motors. Note the drop-arm brass weight. This one is a 4.5" Stock Car model. Most frames had been designed by Team Champion's star, Bob Cozine.

At right, a  4" sports car model. Most frames were nickel plated but some had a gold finish such as this example.

 

Champion issued their pro-racing controllers at about that time, made from recycled 1966 Strombecker tooling. Made with translucent red plastic handles, some versions are known to be the first pro-racing controllers using micro switches for improving the dynamic braking and full-power voltage. The interesting set of handles shown here was molded in clear plastic and was hand-painted by the late Dave Bloom, a great painter in slot car racing history, for long-time Champion president, Bob Rule. At least two sets of these handles are known to exist.

 

Later "500" series motors
 

In mid-1967, the Mabuchi-based "507/607" line with a single-sided can vent hole were replaced by an all-new, American-made can with a thicker chrome plated one-hole design. Christened "517" and "617", these were not only powerful but had better endurance qualities. There are several variations of those motors, and they all received the now familiar white paper label with the exact definition for each motor, and often the wire diameter of the armature. These motors had the Mabuchi-like retaining tabs for the end bell, but they were too thick to be practical, so the cans received two holes on top and bottom, and two flathead slotted machine screws were used to attach the end bell.

The motor at left is an unusual "517" using a leftover Mabuchi one-hole "5001" can.

The new Champion "517" can with the early aluminum can bearing housing. This American-made can marked the final break with Mabuchi. It used the Champion Celcon end bell and Champion ARCO magnet with the one-piece nickel plated shim and a single retaining spring. The end bell was affixed by two M2 flat-head slotted screws that would remain the only assembly method for Champion motors all the way to the end. Only Mabuchi parts left were the motor brushes, of which large remaining quantities were available.

From left to right: later "517" can with sintered bronze bushing, early "517" can with aluminum bearing housing and even earlier short-lived "517" with Mabuchi can.

Second-series ARCO 33 magnets with one-piece shim inside a 517 can. The shim should have also enclosed the top of the magnets as they were offset in regard to the armature! If you are running one of these, make sure that you add two small strips of steel on top of each magnet so as to center the armature properly.

 

It is more common to find the "507" and "607" motors in such a packaging than the "517" that was quickly marketed inside clear plastic boxes with a yellow vacuum formed plastic tray.

This "517" represents the pinnacle of Champion products of the late 1960's and was used by many with success to win numerous races nationwide. Chrome plated springs, shunted brushes, careful assembly and the best magnets in the business, plus excellent armatures of which the sole issue was the use of solder for commutator terminals instead of welding.

 

 

 

The "517" in its later plastic box. It featured shunted brushes, twin-shaft armature, chrome-plated brass spring posts sleeves, but still had the arm dynamically balanced by grinding the stack, rather ugly but certainly not affecting the performance. The "517" was Champion's first motor built with an American-made can and end bell. All later Champion motors were sold in similar clear plastic boxes glued over a card describing the product.

 

 

A typical period "517" installation is seen on this 1967-built Californian Honda F1 car with John Cukras-inspired chassis by John Hale, the owner of Santa Ana Raceways and occasional pattern maker for Cox Hobbies. The black end bell used here is a Mura. The body is a Russkit Honda 3-liter F1, a very popular body at the time.

 

In 1968, things got a bit confusing at Champion. Jim Williams had lost interest in the company and hired a new manager, Bob Rule, "Mr. YoYo". Rule later bought the company from Williams and became its president. The Champion works racing team changed drivers almost on a monthly basis, and things were just not the same. As the industry began to fall apart and most established manufacturers bailed out of the hobby or collapsed, what was left were the pro racers-designed product lines and the emergence of Parma as an Industry leader, that for the next 20 years. Champion kept up in the motor department, as the Mura days had not quite come on a national level. For a while, a Champion mill was THE motor to have in you raced in the UK, thanks to Champion of Europe's very active importer, B.I.C.O. Multiple products were re-labeled and re-named by the British Company, and they had their own team of pro-racers such as Louis Meyerowicz.

A new company, "Champion of Europe", was created to distribute the product over the European continent. The Champion of Europe products had their own packaging, especially the motors which were sold in very attractive red and black boxes. They were assembled and distributed by B.I.C.O., a London-based company. They are extremely scarce today even on the British soil, as prices were dreadfully expensive at the time (twice the US price) and sales limited to a small nucleus of very serious and somewhat wealthy hobbyists.

At left is a sample of their products, an "Orange Picker" open-class motor with a 24AWG wire and ARCO Blue Dots magnets. The intact packaging that includes the card is scarce.

 

 

A version of the 525 became the "Bob Cozine Signature" motor, the most sought-after motor in the collector's world along with the Mura/Cukras "pink" D-size motor with the flower-power decal. The Cozine-massaged motor (but not personally built by Cozine) was all black, with Bob's "signature" stamped in white on the blind side of the can, and had special threaded precision hardware instead of the usual self-threading screws previously used.

 

 

This hardware was nickel-plated over highly polished slotted screws. The end bell was all new (and very difficult to find today) and had the nickel plated bearing cast into it, a first in the industry. The remaining hardware was now un-plated copper. Recently, the author was privileged to discover a small cache of such rare motors and to offer both Bob Cozine and Carl Ford each a mint example.

 

 

The "Cozine Signature" is highly sought by the collectors but is quite rare today. It was marketed in the usual clear plastic box glued onto a card.

 

 

The dual-shaft Cozine hand-wound arm did not look any better than stock production, but the few tricks provided by Bob, along with clean assembly, made it a reliable performer. At a time where new products were issued on a weekly basis to keep up with the competition, the Cozine motor held its own for a while. Eventually, the black "16D"-sized can became the basic motor for Champion's low-cost ready-to-run cars sold in raceways, while a brand new motor was devised, the Champion "C" can.

 

The third generation RTR models

 

The "6" series of high-performance Mabuchi 26D-based motors hung-on until 1970/71, when they were unloaded under the "Charlie Brown" name, as a Group 12 motor ("612") following the new NCC (National Competition Committee) rules established between the surviving manufacturers to try saving what was left of the industry. But a revolution was brewing and exploded in early 1968. Gene Husting, a reformed drag racer and world-record holder, had built a revolutionary car with its motor mounted at an angle to the rear axle, allowing the use of smaller tires than on conventional sidewinder chassis. With better weight distribution and negative torque reactions under acceleration, this was an instant winner. It took several months for Husting to convince the pro racers, but when it happened, the inline chassis were history. Champion found themselves in a panic with a huge load of unsold obsolete Inline frames the very day after Mike Steube won the first Pro angle-winder race in California. So they were sold in low-priced kits all the way into the 1970s.
When the "angle-winder" revolution took place, Champion began tooling new chassis and parts. The first issue was of a dual-sided chassis using a stamped steel center section with a plate drop arm and small hinged side pans. These were not successful but were later used in many factory assembled RTR and kits. They used whatever motors were left unsold as technical progress took its toll on available inventories.

 

Champion's lowest-price angle-winder frame was this stamped-steel unit with floating side pans. This example was sold as a "Factory-Second" with all what you see including obsolete threaded front wheels and axle and re-soldered drop-arm hinge, along with a Lola T70 MKIIIB clear plastic body. This was sold inside a small cardboard box of which graphics were as usual, devised by Ray Gardner. Nothing was wasted at Champion.

 

Champion retooled and introduced a plethora of variations of angle-winder frames, closely following the evolution of pro-racing, both on the East and West coast of the United States. After the resounding defeat of the British pro racers against visiting mild-mannered Bob Emott at Tottenham Raceways in 1970, Champion concentrated on getting product information from their American team members and utterly ignored the advice of their British contingent. This led to the strangest of situation when Champion Team member Ed Lewis (for a time the general manager under Bob Rule's presidency) devised a full sidewinder with very narrow center section and wide pans, and actually lucked-out by winning a local pro race by surviving the demolition, rather than by pure performance. After Car Model magazine published an illustrated story about the hopeless contraption and after an unsuccessful visit by Ed Lewis in the UK where he failed to make the program, many top-level British Pros went blindly into this new avenue, and for nearly a year, led by Barry Magee, Trevor Crouts and Bob Hallums, ran full sidewinder aberrations, that no one else used in the USA with any success against the more effective angle-winders.

 

 

This nickel plated production frame, issued in 1969, was fitted to many RTR cars through 1973. This Lola T160 uses a Dynamic body (sold by Champion) and a typical NCC Group-12 motor. The NCC was a new organization between Champion, Mura, Riggen, Dynamic, Cobra/Phaze III and Dyna-Rewind to attempt what never happened since the beginning: establishing a national set of racing rules. It failed and eventually the local associations combined to form the national USRA. The chassis has the basic features of a mid-1968 pro-racing design, but was already obsolete by the time it was issued.

 

Such was the pace of progress in racing. Note the Cox guide, angled gear and typical Champion white lead wire, used in their motors since the advent of the "517".

 

 

The motor in this RTR model is an NCC legal Group 12, featuring an unbalanced and uncoated armature. The can is the old "517", recycled with an endbell design that had a brass plate retaining the endbell bushing, making it necessary to fit the motor in the frame, then use two screws to attach both the frame and the bearing plate to the motor, a very undesirable and weak design feature.

 

 

1969 brought the surviving manufacturers together in a new association, the NCC (National Competition Committee). One of their new racing classes was the "Group 20". Using this spec frame and a spec motor manufactured by several companies, one could assemble an angle-winder car that was supposed to be equal in performance to any car in this class. Unfortunately, this frame was made of very soft steel and was easily bent in mild crashes. Since reinforcement was illegal, the class only lasted until mid-1972 and died from lack of interest. it was revived into "Group 27" where open-class chassis were used with the new milder motors, and has survived to this day.

 

 

This 1969 Series 3 kit in the Series 2 box  features the gold cadmium plated angle-winder chassis in its first version with plate drop arm, a clear plastic Ford Torino body, a Group-12 motor and all required parts to complete the car, including an ARCOlite axle. The clear-plastic blister is the same as used in previous kits, with some blisters empty as parts are packaged differently.

 

Champion kept producing their black motor, changing the name as they evolved, from "Group 7" with blue or green endbell, to "Orange Picker" with orange endbell, to "Big Louie" (a UK-only issue) etc.  Of course there was a Group 20 version, as Champion had obtained the "spec- frame" contract from the NCC. Unfortunately, the new end bell design was a bit of a disaster as the end bell bearing was now soldered to a brass plate, bolted with self-tapping screws.

 

 

 

Problem was, the molding had too little material to apply a decent torque on the screws that were also used to fasten the motor to Champion's angle-winder frames. The picture shows two versions of this endbell, the later with larger side vents to match a notch now present on each side of the can.

 

This motor design caused lots of desertion to the Mura camp, and it was grand time for Champion to devise a new motor. By 1971, with the help of Joel Montague and other notable pros, Champion revised their tooling and came up with the new smaller "C" can to compete against Mura's new, Bob Green-designed, "Green" can. named after Mura's own,  the new "C" can featured two elongated holes on each side and used the latest ARCO "white dots" magnets, now tightly fitting inside the can.  As with the new Mura "Green" can, a shim was no longer needed, as both were significantly smaller and with a lower profile.

 

 

The Champion "C" can motors were extremely successful in racing, especially when prepared by one of slot car racing motor geniuses, Joel Montague. Under the names "Camen" and "Pooch", these motors totally dominated the racing from 1971 to the mid-1970's on the Atlantic coast of the United States, until Champion stopped manufacturing them altogether. Two types of cans were produced. The first was a folded model that gave entire satisfaction, but apparently the tooling broke and was replaced by a drawn can of thinner gauge of which tolerances were far from satisfactory. The motors were also hard to assemble with the miniature screws and hardware that was less than great.

 

The new motor required a new end bell. It was dark red and the can was attached as before with two small metric screws, but now with small tongues projecting from the can with recesses in the end bell to receive them. The usual slotted screws held things together. It used Mura-like hardware. By now, the performance envelope was bursting at the seams, and by 1972 the first sub four-second lap times were recorded on American Blue King tracks. Earl Campbell did just that at Speed & Sport in Lynwood, California. But it was not with a Champion motor. If Champion was winning the races in the East and South, Mura was slowly getting a firm grip on the motor parts market, and Champion was sliding fast. The end was near as the market was declining even more. By 1975 it was all over, and Champion shut down their motor production and began marketing Mura motors.

The second generation of Champion's wire angle-winder chassis issued in 1972 seen in this factory assembled Chevron B16 RTR had a modified drop arm with a large square cut-out and reinforcements on the front of the side pans. By then, the Cox guides had run out and Champion was using blue-dyed "Jet Flags", originally produced by SimCo and now marketed by Associated Electrics.

 

 

Last of the line, this Champion C-can motor with the Mura endbell and hardware was the last motor sold under the Champion label in the "Classic" era. Soon, cobalt magnets surfaced, and these old-technology can motors became history.
