Drifting in Loiter

ArduCopter Traditional Helicopter

In Loiter Mode my Trex 450 Drifts to the right, In Alt hold and stabilise on a Calm Day it will hover in the same spot with almost no stick input. It doesn’t appear to be toilet bowling as the drifting is always to the right. Don’t know what has changed as I have been doing auto missions with not problem up to a few flights ago. There is is also a small oscillation problem that comes and goes in the roll axis.

Below is a link to the log file

Figured out the problem. There was a few clicks of right trim on the radio which made the stabilise hover good but messed up the loiter.
