This is a new one to me. At altitude, I can be facing into the wind (15mph or so), then yaw either left or right to the crosswind and it will drift anywhere from 15-100 ft.. then stop, and slowly return to that last GPS position and hold. My last stick input was the yaw to left or right into the crosswind. I have recalibrate the EMU, and remote...another funny thing is that it will not do it all the time. I would say about 30% of the time. Anybody experience this? Brake is set at 70.
