there's no reverse on the airmaster one.. and it's alittle tricky to program and calibrate with a pistol... but it's good for a gas conversion.... since you don't use reverse.... when you do use reverse, the motor does nothing or brake (which doesn't matter) but the servo will brake the vehicle... because I used a cheap tower pro 60amp air esc in my inferno a while ago.. and it worked fine.. just I have to calibrate it every time I change packs...
