The idea behind this proxy is to encourage scratch building scale model slot cars, and racing them. One reason the 1966 Can Am season was chosen is the spirit of innovation and experimentation that the series represented. You may find the rules are more permissive than some proxies, this is to allow experimentation, while keeping the series a scale model one. The intention is to not allow the entrants to devolve into thingies or wing cars.
The 2018 1966 Can Am Scratchbuild Proxy will feature a Constructor’s Trophy along with race results, points winners and a Concours. The Constructor’s Trophy will be awarded to the car with the most outstanding combination of performance, appearance, and build quality. Only cars whose body shells have been created for this series will be eligible for the Constructor’s Trophy.
Entries must be 1/32 scale (as claimed by the manufacturer) model slot cars of Can-Am cars entered in events in the inaugural 1966 Can Am Challenge season. Entries will be limited to 24 cars, with a minimum “quorum” of 12 cars.
Body shell Construction and Appearance:
Body shells may be Injection molded plastic, resin, wood GRP, and vacuum form bodies pulled in an opaque material, with separate glazing. All entries must have some dimensional modeling of surface details such as panel lines, rivets, Dzus fasteners, etc.
Entries must be a reasonably scale representation of historic Can Am car from the 1966 season. Historical liveries are encouraged, fantasy liveries are permitted. (fantasy liveries must appear true to the period.) Wheels/inserts must be period correct
Entries must include the following detail: a period-appropriate driver with head, arms, hands, and partial or full steering wheel; period appropriate wheel inserts; clear windscreen, roll bar, some 3-D engine detail, where applicable, exhaust system and mirror(s).
Entries that do not comply with appearance regs will be assessed penalties.
Chassis and Running Gear:
Chassis may be purchased, fabricated or 3D printed. Material open. Carbon fiber chassis must be free of splinters or any other debris that may cause injury or damage to tracks. Chassis rails should be inboard of body sills, and not easily visible.
Drive orientation: open
Motors are limited to those factory rated at 20k rpm or less. Motors with excessive draw, that slow down other cars, or trip circuit breakers will be DNF for that event.
Chassis wheelbase must be to scale +/- 2.5%
Maximum width of bodywork of any entry is 60mm. Maximum width of the outermost point on wheels or tires is 56mm Penalties will be assessed for over-scale cars on a sliding scale. X points per 1% over or under tolerance.
Minimum ground clearance is 3/32 (2.4mm) except at driven gear, tires and guide. All four wheels must make contact with the ground, and roll when pushed over a flat surface.
Guide must not be visible from above, while oriented straight ahead. Any guide intended for 1/32 cars is permitted, but if they prevent a lap from being completed due to being too long or deep, that will, of course be a DNF for that event.
No traction magnets permitted.
Car owner’s name to be written on the bottom of the chassis
Plastic or alloy rims maintaining a scale size/ appearance.
Tires: Rubber or urethane only, no Silicone.
Minimum width 7mm, Maximum width 10mm.
Tires must have sidewall bulge on the outsides ( insides may be flat)
