I've flown in +30 mph wind, which was hitting the right side of the AC. Whilst it did drift a little off course, but it was nothing major. I turned it into the wind at full throttle and it was creeping along at 5-7mph, paused and it held its own.
Only on one occasion have I had the AC completely static when trying to return home, so that must have been 35mph+ @ 360' and almost dead calm on the ground. I dropped altitude and it began to return and at around 200' it was around 11mph. At 100' it was back to 30mph.
These ACs are amazing.
