3rd party bodies?

Where can you get bodies for the Bit Char-G without using the ones the Hobbico or Tomy has?

Ive heard that you can use many slot car bodies with a little modification, and that there are some websites that offer custom-made bodies...

Some nice bodies to have would be the Ford GT-40 and some Le-Mans body styles...

... Woah. Explain that stuff. I wanna know HOW you did that.

Oh-tay! But it'll be one LONG thread....and keep in mind that it's not done yet, and much of it is theoretical

XGP means "eXperimental Gran Prix" meaning i designed the car around the idea of a touring car, a car designed for max top speed as opposed to quick acceleration...

The 3.8 means 38,000 rpms...mighty big motor designed for straight-aways instead of tight cornering, like a touring car...

I plan to make the custom molded chasis from a plastic-resin kit...just go to the hobby or craft store and pick up one of these kits, you pour the liquid resin in and then add a couple of drops of the catalyst and two hours later you have a slab of plastic that's as hard as a rock. Good stuff.

To get the battery set up I have, you need two Sanyo 1/3 AA size NiMH (Nickel-Metal-Hydride, much better than the stock NiCd)...wire them in a parallel connection, and boom! You have twice the longevity. Don't wire them in series, or youre gonna fry the circuit board! Big NO-NO!

Porportional means you can choose how much of something...like with steering, you can adjust how tight the corner is made, and with throttle, how fast you make it go...much easier to controll that way. It's remarkably simple to do...just get pressure sensitive buttons, and rig it up so that it changes the frequency of an ocillating circuit, and boom you got porportional whatever...

The constant variable transmission is an idea that mechanical engineers have been throwing around for the past 50 years or so...most automatic transmissions shift gears to change gear ratios, but "CV" transmissions use cones so that no gears are involved...the only problem is that in practice on large systems, the slack that was needed in the belt between the two cones causes the belt to jump and twist and break over time...not untill recently was this problem solved with the use of "sprocket rods", but it's not widley used yet- but it will be!

On the small scale, constant variable transmission works extreemly well, my system has the motor mounted above the electronics package, and the cone sits in the compartment where the motor used to be, and small rubber bands work as belts. Because rubber is extreemly elastic, the belts wont need to have slack and should have a relativley long life.

So this has been done in Bit Char-g's? Any Pictures?

I'm into motorsports and the touring car races I see have a lot of tight corners and turning was a big factor. Most of the cars that prioritize raw power and straight line are Drag racers.

Yes, but I don't have a digital camera or a scanner so the best I can manage is:

Theres the CV cone! Enjoy!

When I talk about touring races having few turns i mean relativley, compared to other types of races where there are tighter turns...Like Laguna Seca compared to Cout'e de Azur...am I using the right terminology? Oh well.

Could we please put this topic back on track? I wanna know where I can get more bodies for the BC-G!
