Trainer Modules & Radio Add-ons

Add-ons that extend an RC radio or a build: wireless trainer modules for buddy-box teaching such as the RadioMaster WT01 and Ranger, voltage telemetry sensors that report battery voltage back to the radio, ELRS firmware recovery dongles and TX module cooling fans, Bluetooth flight controller configurators such as the SpeedyBee BT Nano, cellular modems and nRF24L01 2.4 GHz transceiver modules for DIY links.

Check that each listing names your radio, receiver protocol or module bay before ordering. We stock RadioMaster, FlySky, Radiolink, BetaFPV and SpeedyBee. Autopilot telemetry radios are in Telemetry Radios.
