I was thinking they should put nitrous bottle in RC but in a different way than real cars.
They should put the end facing the back then when you push a button on your radio a servo some how unscrews the end and the nitrous flies out giving the RC a boost.
This would work different than NOS from a real car.
It might work becasuse my friend has a bottle of nitrous for his paintball and he said he unscrewed the end and the nitrous bottle flew out of his hand and flew and smashed the wall. so it could make your car have so much boost.

JUST AN IDEA
