i also want to know how do u make fire come out from the exhaust?
You can't do that with nitro. On real cars you can tune it to run so rich that fuel spits out of your exhaust and attach a spark plug at the exhaust tips and wire it to power supply. But your car will have crappy performance. Only in the movies does a car that runs pig rich does 0-60 in like 2 seconds......LOL.
