Venom's VR3S is a low cost 2.4 GHz transmitter/receiver combo that makes a great upgrade from those old AM systems. Endpoint adjustment on the steering and throttle channels is made simple with the use of small adjustment knobs. This allows the user to tune their control for their driving style or conditions at the time. The included 3-Channel micro receiver is small enough to fit in anything from the smallest 1/18th scale vehicles to the large 1/8th scale vehicles. The VR3S also is great for use in boats, not suffering from reflectivity issues of other 2.4 GHz systems on the market.
