13. QX105 DSM2/DSMX BNF Version binding procedure and Satellite receiver setup

1. The QX105 DSM2/DSMX BNF Version integrates a DSM2/DSMX compatible Satellite receiver. The binding procedure is as follows:

1. Connect QX105 DSM2/DSMX BNF Version to a computer and open Betaflight configurator. From the CLI tab, type: "set spektrum_sat_bind = 9" for DSMX radio or "set spektrum_sat_bind = 5" for DSM2 radio.
2. Type "save" and after the Flight controller reboots, remove the USB cable (= Power off the board).
3. Wait a second and reconnect the USB cable. After a cold start, the satellite LED (Orange color LED) should start blinking, and the transmitter should be turned on while pressing the bind button.
4. After binding, the satellite LED should be solid. Connect Betaflight and use the receiver tab to test that the satellite is working correctly.
5. Final step: Go to the CLI tab and type "set spektrum_sat_bind = 0" and then type "save". This must be done so that the satellite doesn't go back to binding mode when the QX105 is repowered.

Diagrams show CLI commands for setting `spektrum_sat_bind` to 9 (for DSMX), 5 (for DSM2), and 0 (to close binding). It also shows the Orange LED Status meaning: Solid - Works normal, Blinking fast - Binding mode, Off - Lost signal.

2. The default receiver channel map for the QX105 DSM2/DSMX Version is TAER1234. Ensure your transmitter is matched with it, otherwise it can't be armed.

Diagrams show RC channel mapping (Roll, Pitch, Yaw, Throttle, AUX 1-8) and RC Deadband/Interpolation settings, with Channel Map set to TAER1234 and RSSI Channel set to Disabled.

14. Arm/Disarm QX105 DSM2/DSMX BNF version

1. The default Arm/Disarm switch for QX105 DSM2/DSMX BNF Version is AUX1 (Channel 5). For most Spektrum radios, the default channel 5 is the GEAR Switch. You can also customize it with Betaflight Configurator. AUX2 (Channel 6) is set for changing flight mode, and AUX3 (Channel 7) is for activating the buzzer, which can also be customized. Suggest using a 3-steps switch to change flight mode.

Diagram shows Betaflight Configurator's Modes tab, with ARM set to AUX1 and AIR MODE/ANGLE set to AUX2. It illustrates ranges for switch positions.

2. Turn on the transmitter and set a switch for CH5 to ARM/DISARM the motor. Some transmitters, like SPECKTRUM DX6/DX6I, use the GEAR Switch as the default CH5.

3. Toggle the AUX1 Switch. The buzzer starts beeping once, and the Blue LED on the flight controller will first turn off and then become solid, indicating the motor is armed. You can also find "ARMED" displayed on your FPV Goggles or FPV Monitor. Be careful and enjoy your flight now!
