View Full Version : True Scale Racing

01-02-2007, 06:05 PM

I'm interested in hearing about True to Scale Racing. I've been promoting this type racing for years on varying levels and feel the need to step up the pace a bit.

I've included multiple choices to the following program proposal and if you would like to discuss issues, please do.

Please don't stray from the subject.

Guidelines would generally be as follows:

Program would include 1/32 & 1/24 Hardbody & true scale Lexan bodies.

Motors would be selected from a range of FK type and the new Pro Slot Euro. Motors would be handout blueprinted and Pros build with spec arm.

Chassis would be modified stamped steel, Euro types up to unlimited. How modified you ask? Enough to achieve proper WB and to accomodate large scale tires.

Tires Spec true scale. Gearing TBD.

Procedural format to follow IMCA style, 1 minute off/no work on car.

Here are some reference points:

http://www.slotcars.co.za/124/index.htm . After perusing this fine South African site go to their links page and check out what's happening in various European Countries as well as in Australia and Canada. Some have quite a head start :o

Also, see http://www.scaleracing.ca/Amerinats%20Intro.htm . I might have to go if only to watch! Great work fellas, I'm looking forward to news.

This is primarily for specualtion of forming up on the US left Coast but also to help access those ideas I think are good ones :)

I already have a 1/24 scale porshe 962 group-c car built and ready to race. It even has working head and tail lights for a 24 endurance race. I also have a c-5r corvette that is about done too.

Tires must fit inside fenders of model body or 3.00” max width, whichever is smaller.

We use 1" diameter tires all around because it has a better scale appearance & the 1/8' axle could be replaced with a 3/32" axle. It's up to you guys. So, what do you think, Bob?

Sorry Russ, I dropped the ball on this one....I've tried picking it back up but I'm afraid I poked a few holes in it while it was down :p :eek:

I've emailed you some comments. It looks very good and I hope to participate sometime soon. Where's your race reports and photos? We could all take lessons from The East Coasts version of D3 as reported on SlotBlog.
