Altitude hold

Hi there

I have just tested my new quad and it flyes very stable but in altitude hold function he begins to oscilate in the altitude so much, that he hit the ground. I think it is a PID problem, but which PID´s are for altitude hold function?

Ok, sorry for the missing informations.

The Copter software is APM 3.01, Ublox LEA6H GPS, HK T6A Transmitter, MP 1.2.80.

Hope it will help to tell me where I have to make the PID settings for altitude hold.

See copter.ardupilot.com/wiki/altholdmode/

Also useful info are motor specs and prop sizes?

I would also recommend getting an external compass for a copter. That will give you the best performance in auto modes
