RE: elec or nitro???
Maybe if had a tank of compressed air feed into the carburetor you could drive it on the moon, no maybe not. YOUR FUEL/AIR MIXTURE WOULD GET SUCKED OUT THE EXHAUST BY THE VACUUM OF SPACE BEFORE IT COULD IGNITE. Besides if your tank of compressed air somehow ignited... BOOM BABY! With enough mods you could drive on the moon, everything that carried fuel or air would need to be stronger to keep from leaking or exploding. Metal fuel tubing, metal fuel tank with screw-on cap ETC. (you'd need rear-exhaust or it would be like a rocket and propel the car in the opposite direction of the escaping nitro fumes).
Due to the weak gravitational pull you could get some serious air on the moon though, you'd need paddle tires because the moon's surface is dusty and like a fine sand.
I'd say electric is the way to go for driving on the moon.
Jeez you could break the RC car speed record, your car would weigh a quarter of it's normal weight and have no wind resistance.
If you jumped too high your car might not come back.
