I have a new composite ROO and have successfully completed three flights takin off directly into the wind, the fourth and fifth turned ugly. There was quartering head wind from SSE at around 3 knots. I began a slow roll out and was at full throttle about 30 feet out, at that time the plane turned sharp into the wind out of control. I did not have the elevon pinned full up at that time however, it was as if the nose wheel still had no authority. Anyone had a similar experience?
