Hey

I have a nitro 4 tec 3.3 RTR and i am running 30% sport nitro. I put my hand infornt of my tuned pipe (exshaust) and there was nitro flying out. Does anyone know what i can do to fix this? Also when i let it idle sometime it dies and sometimes it doesnt and when it doesnt i press the accrelarte button right when i press it the engine always truns off does anyone know whats wrong?

Thanks
