Nitro Zipzap?
 

Resently I saw a tiny Cox nitro airplane engine and thought it
would real cool to put a little TeeDee.010engine
,a Pee Wee.020 or even a Babe Bee.049 but that might be too big. I just that might be cool it would be VERY fast but but with like no control. It would be expensive but pretty cool. Its just a thought but I would spend the money on it if it would work. Tell me what you think about I know its probobly possible...

I think someone tried something like this once, maybe for an X-Mod. It would be extremely hard to work. First of all, even the tiny .010 TeeDee engine is over 1/3 the size of the car. Second, you can't turn the engine off, you just run until the fuel runs out (these are usually made for free-flight and control line aircraft). Third, The engine is optionally proportional, but you need a servo to actuate the throttle. And last, good luck finding micro size gears capable of withstanding the torque of these engines. In 1/24th scale, this would be a much easier (but still complicated) project to do.
