Throttle stuck

I thought you were at old firmware because there should be a icon at the topbar as the Herelink Settings App’s notification. It was not there in very early firmware versions.

If you have gone through the hardware joystick calibration, they shouldn’t behave like that

For the pairing problem, you will need to update your air unit to beta as well.
When using the flasher, put beta behind the command
eg: flasher.exe beta
