RadioMaster Pocket setup: a practical checklist.
The Pocket uses EdgeTX and comes with different internal radio modules. Identify your radio variant and receiver first: ExpressLRS and CC2500 setups follow different procedures.

Prepare the radio and workspace.
Disconnect the aircraft battery and remove its propellers before setup work. Follow the Pocket manual for installing the specified pair of 18650 lithium-ion cells with correct polarity. Use the designated charging port and the manufacturer’s charging instructions.

Check the antenna and firmware.
Make sure the antenna is fitted before transmitting. Note the current firmware and exact hardware version. The Pocket ships with EdgeTX; updating is not an automatic first step. RadioMaster advises updating only when you understand the procedure.

Calibrate the controls.
In EdgeTX’s Hardware settings, select Calibration and follow the prompts. Move each stick left and right, then up and down, using normal pressure at the endpoints. Avoid circular movements or pressing hard against the stops.

Review the basic settings.
Check the date, time, battery range, stick mode, and audible alerts. For quieter menu navigation, No Key retains warning sounds; Quiet suppresses sounds. Resolve startup warnings rather than simply hiding them.

Match the receiver and radio module.
For ExpressLRS, the transmitter and receiver need compatible firmware: the major version number must match. Follow the binding method for the receiver and installed version. For the CC2500 variant, consult the Pocket manual and the instructions for your receiver’s supported protocol.

Check the model before flight.
A successful radio bind is only one check. Follow the receiver and flight-controller documentation to verify channel movement, arming controls, link information, and failsafe behavior. Keep propellers removed during bench work. Complete the official preflight checks for your setup before flying.

Choose the USB mode for your simulator.
Connect a data-capable cable to the radio’s USB data port and select Joystick mode when prompted. Then follow your simulator’s controller mapping and calibration process. EdgeTX distinguishes Joystick, Storage, and Serial USB modes.
