Loosing altitude in LOITER and auto

Flying straight in FBWA the plane flies pretty level, but it seems that I am loosing lots of altitude in loiter which is more like a spiral dive.

Is it the pitch2srv_P I have to increase, or if this is associated with turning maybe a ptch to roll?


So what it actually looks like it is happening is that I am gaining height in loiter and loosing a lot of height when turning in auto.

What would be the best way to reduce the altitude loss in turns?



Thanks Stefan

I have now changed the PTCH2SRV_RLL and PTCH2SRV_P and I have seen some improvement in the behaviour of the plane.

I have attached a log for advice.
