Have you tired Calibrating the GPS/Compass?

I had a drift when switching into GPS mode but after i calibrated it if flew fine.

I also have noticed that if i take off and fly and switch to GPS straight away then it doesnt hold very well.
If i flyin Attitude mode for a short while then switch into GPS then i often find GPS holds better.
There maybe some strange auto trimming going on in there that the GPS requires.
Dunno but it works for me.
