The GL200 radio transmitter contains all vital elements on one board. The board receives state of control sticks and switches (some of which have their own boards), then transmits the control signal. It also receives the OcuSync video signal and telemetry from the drone and provides USB interface for reading the data and reconfiguring the drone from a mobile device.
Only one variant of the RC is known.
