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.

Hi! I know your post is a bit old and arducopter firmware have since changed. Just flew my hexa in loiter mode (I too don't have sonar) and like you experienced it started climbing and climbing and got worried so flip back to stabilize.

Question: were you able to solve that problem of flying away in loiter? How? Thanks.

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 also have altitude gain when I operate the yaw.
