INAV Troubleshooting - Quick Tips

1. FIRMWARE  

Are you using the correct firmware target for your board? 

Note that the SpeedyBee F405 Wing Mini board uses the WING target, NOT the MINI target.

2. BOARD ORIENTATION 

Does the animation move the same way as your plane?

Set FC orientation using the Alignment Tool if the board is not facing forward

3. INAV MIX in the RADIO

Do Not set up V-Tail or Elevon mixing in the radio, that is done in the INAV Mixer

Must use this basic mix in the radio. I call it the INAV Mix.

Ch1 100 AIL

Ch2 100 ELE

Ch3 100 THR

Ch4 100 RUD

Ch5 ARM Switch (must be Ch5 for ELRS)

Ch6 7 8 etc. for your desired flight modes, but always include a switch position where no modes are selected. This will allow for ACRO.

In the radio, adjust the endpoints of Ch 1 to 4 to give PWM range of 1000 to 2000 in the INAV Receiver graphs.

4. OUPUTS Page - Enable Motor and Servo Output

Choose the correct ESC Protocol and Servo Refresh Rate for your gear. 

Use STANDARD and 50 Hz if they are unknown.

Use the slider controls on this page to calibrate Standard ESCs, and check if the motor runs. 

5. PORTS - Enable separate UARTs for Serial RX, GPS and Digital FPV if required. 

SBUS Rx with F405 boards require Serial RX to be on UART2.

6. CONFIGURATION - Turn On "GPS for Navigation and Telemetry" (if GPS will be used)

7. FAILSAFE - Only set as RTH if you have a GPS setup.

Arming will be prevented if failsafe is RTH on a non-GPS setup.

8. RECEIVER - Connect the receiver to the Serial RX UART 
Choose the Channel Order for your type of radio. AETR is most common
Choose the Serial Receiver Provider for your receiver - CRSF for ELRS, SBUS for SBUS etc.

Check that the Rx is bound to your radio.

Check that the INAV Channel bars for Roll, Pitch, Yaw and Throttle move to the RIGHT when moving the radio sticks UP and RIGHT?

If one moves to the left then you may have reversed a channel in the radio.

9. ARMING PROBLEMS - Read the Arming Flags message along the bottom of the INAV window and in your FPV goggles. Type STATUS in to the CLI for more clues.

Arming is only possible in ACRO, HORIZON, ANGLE or MANUAL modes, and GPS must have acquired at least 6 satellites and a 3D lock.

To bypass the Arming Flags, hold the throttle stick down and yaw right while arming. 

BEWARE this is for troubleshooting only and is not a safe flying condition. 

Disconnect the battery to clear Arming Flag bypass.
