If youre after something to give you a speed readout, I`m sure Venom make a Speed Checker........this mounts into the car and has an LCD screen which gives you a readout on the maximum speed.....perhaps someone who owns one of these could shed some more light on its various features?
NTC3 = Nitro TC3, made by associated. it is a car kit. the NTC3 Plus is a ready to run car. it has 2 speed gearbox and a .15 engine. one of my friends has one, it is really fast, with a good quality radio gear.
