MultiGov Pro is an advanced multifunction RC helicopter governor. MultiGov Pro keeps your RC helicopter rotor speed constant by monitoring the helicopter motor speed and automatically adjusting your model's throttle servo. It can run in either a standard smooth flight mode or aggressive 3D mode. You can even switch between the two modes on the fly in flight! In addition, MultiGov Pro has built-in support for automatic control of a mixture servo by monitoring the motor's cylinder head temperature. Mixture control is not required for governor operation. Configuring MultiGov Pro is a snap with our detachable backlit LCD configuration module. Just plug it in, configure, and unplug it when you are done. If you have multiple helicopters and already have the LCD configuration module, you can buy just the MultiGov Pro unit without the LCD to save on costs.
