Ergonomically optimised hand-held transmitter for tireless, fast-response control of small model aircraft, RC cars, trucks, multi-function models and boats. Control signals generated by modern micro-computer, ensuring high positional accuracy and centring precision. Four control functions. Separate fine-control trims for all stick functions. LED battery monitor with variable flashing frequency for visual warning of low battery voltage. Ratchet function on throttle stick. Integral switchable V-mixer based on a clever combination of control functions; provides fine control and scale turning and rotating manoeuvres with models such as tracked vehicles, twin-motor boats, and V-tail model aircraft. MODE switch: MODE 1 / MODE 2 for dividing the V-tail function between two transmitter sticks. Servo reverse switches for simple change of servo direction, available for all control channels. The switches are arranged in a recessed position on the underside of the case, protected against accidental operation. Simple crystal change; no need to open the transmitter case. Integral Pupil function on the front face: allows easy Trainer lead access or connection to a flight simulator. Charge socket for recharging integral high-capacity Ni-MH transmitter battery.
