Calibrating the XY thermopiles

Sometimes I feel like "one step forward, two steps back".


My Easystar with Ardupilot is ready for my next test flight but..  calibrating those XY thermo's - I can never get this to work in manual mode.  Perhaps it's me but I can only get good Roll/Pitch values when I start up the Ardupilot in Stabilize mode.  However, this is chewing up my elevator servo as it does an extreme angle during the startup phase.


I can probably avoid this by unplugging the servos until the XY calibration is complete. Urgh.


Can anyone offer advice?  Is this normal?  Should I always initialize Ardupilot in Stabilize mode?

    Could you be more specific?
    And can you enclose your header file? It's hard to talk about your setup without that.

    Are you doing the radio_setup sequence at the beginning? try not doing that. Calibrate the thermopiles is easy, just rotate the plane so the IR windows can see the sky and ground.
  • I always start up in manual mode.

    Do you have a Z sensor?
