Ultra-small, lightweight piezo gyro designed to stabilise the tail rotor function in model helicopters, or any function in a fixed-wing model aircraft. The piezo sensor is very sensitive, with the result that it corrects even the slightest model movements instantly. A micro-processor is responsible for all the signal processing and also the special temperature compensation process.

A potentiometer is fitted to provide infinitely variable gyro sensitivity (gain). The unit is extremely compact, making it ideal for micro and mini electric helicopters.
