Zero Alpha is state-of-the-art digital engine speed governor for model helicopters which automatically monitors the speed and maintains constant RPM.

Specification:  Digital advanced control  Direct detection of engine rotation  RPM resolution: 0.0003Hz  Speed stability accuracy: 1%  Control response: 14ms  Range: 10,500 ~ 21,000 rpm  Operating voltage: DC 4.8 ~ 6.0V  Current drain: 40mA ( 4.8V )

It not only works very well in all maneuvers, but also has a very user-friendly interface and easy to setup. The Zero Alpha 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.

• High-speed CPU and advanced feed forward control algorithm
• High brightness LED for RPM display
• Adjustable gain for the control response
• Adjustable mounting device
• Light-weight and low power consumption
