The Zero α II is a state-of-the-art digital engine speed governor for model helicopters which automatically monitors engine speed and maintains constant RPM by using an active integral control algorithm. The Zero α II now is compatible with a 2.4GHz radio system as well as having the capability of operating in a high voltage DC system. It not only works very well in all maneuvers, but also has a very user-friendly interface and easy to setup. The Zero α II is designed to govern the engine speed between 10,500 and 21,000 RPM. Like all the PCM radio accessories, this governor will only work while a transmitter signal is received.
