TECS_PITCH_MAX vs NAV_TAKEOFF minimum pitch

Posted by Jacko on January 2, 2015 at 4:07pm

Hi

I can get ardu plane to control minimum pitch on auto take off. I seek to get a steeper climb out angle from hand launch in small areas, but setting NAV_TAKEOFF minimum pitch to say 30 or so has no effect - always climbs away at 15-20 pitch. I have also increased TECS_PICH_MAX all the way to 30 but makes no difference.

Is there any other requirements I'm missing to make this work?

Thanks

    @Jacko: Any success with the auto takeoff feature?

    My plane always tries to level after launch instead of climbing to commanded altitude of 25 metres. The motor switches ON after launch but the Elevons try and pitch down the plane instead of climbing up. Any help is appreciated.

    Thanks in advance.

    That sounds reasonable. I need to read up on the params again..... I don't have the pitot tube fitted yet but assume TECS still works with the GPS speed?

    Thanks for the reply.

    You might have airspeed bellow min setting ,then TEC limits climb angle to maintain speed

    Anyone?
