throttle problem at startup

i have a big problem since some meet.

my hardware:

complete ardu with thermopiles and code 2,6 , ublox 5, airspeed disable in header file.

problem:

I have often enough flown without probleme.since 2 days I have big problem.

normaly i plugin my battery then wait for sat fix.after the fix i testing all funktions.reaction on manually mode and spinning engine if i switched to AUTO or RTL modes.

now the engine is only running on RTL mode ! on AUTO mode engine is quiet or run for only half second ! i can fly manually.also the RTL works.but, if i switshed in auto mode, the plane change in right dierection, but the engine stopped !
i have the problem with learning the rc-limit at startup and without .

i found out that i have this problem only WITH sat-fix.the same test indoor without sat view the engine running in both modes !??!
I have not changed anything ! and in first 2 weeks, the ardu works fine....

after MANY MANY test i am going crazy :-(((

what is with my ardu ???

    I see throttle min in the header is set to 0. Change that to 30. and see what happens.

    I don't think that's a great default setting.
  • If the mission file is the only thing you have changed then check the altitudes of your waypoints.

    It sounds like ArduPilot may be cutting the throttle to reduce it's altitude (you have minimum throttle set to 0 and the problem only occurs in AUTO when you have a GPS lock...) RTL works on an altitude offset above home so likely wouldn't be affected.

    Olli,
    I can't help without your header file. Please upload it with your post.
    Also if you can zip up your complete ardupilot folder, that would help as well so I can duplicate the issue.

    Thanks,

    Jason
