The time off PH was only two seconds. i would not risk anything. In past when i need more time to turn PH off the heli make circles which were getting bigger.

Yestergay i had more courage. The problem was at 1.19 to 1.35 min
The circles are nearly 6 meters.

=] lets be clear, if the SK unit is not 100% levelled and 90 deg in either direction to the mast, which has resulted in linkage adjustments to trim this error out, the GPS is working with false datums, ie, it can't find a reference point and gyrates in bigger circles looking for it!

also please turn on GPS sats in the pref tab>playback settings....

is it normal in position hold the heli is jerking a little up and down and rolling a little to maintain the position. in light wind 15-20kmh. or it is my settings that are not optimum?
it fly great, I am happy with my cyclic and tail settings, SL speed...but the heli is jerking when in position hold. it is also jerking while flying back home in RTH (but this was in stronger wind)

I had a similar problem. I turned up the head gain, and the TBE went away.
