The MR1S 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 video signal and telemetry from the drone and provides USB and WiFi interface for reading the data and reconfiguring the drone from a mobile device.
Known variants of the RC are below.
| Marking | Overview |
|---|---|
| MR1SD25 | Version with CE certification, for EU countries. |
| MR1SS5 | Version with FCC certification, for US but also used for most non-EU countries. |
