1.On field i switched alt_hold and quadro starts to get higher and higher till i flip back switch to stabilize mode and same with loiter... hmm altitude must calulated automaticly from the position i switched alt_hold button...but whats wrong then?

I've got a similar problem on an Octo which only requires about 1/3rd throttle to hover. The TRIM_THROTTLE is at 342 after quite a bit of hovering and flying about. I have no sonar.
In previous posts I read that this is a feature of light 'copters due to the throttle deadband in alt hold. Is there no other solution as until I have confidence in the 'copter I don't want to add a camera.
I had this issue and found that the sonar sensor was catching the very edge of my battery pack. (it has a very wide beam) Moved the sonar sensor lower and it works perfect now.

I also have altitude gain when I operate the yaw.
