Last night I had my bird up to around 400 feet and hit go forward sent it about 1/2 mile ahead. Turned it around and sent it back. Well there must have been some wind up there because it looked like a shooting star as it came back across the sky, went overhead and kept going. I looked at my screen and it read 52mph! At this point it was out of view again and I used the "radar screen" to turn it around and bring it back. On full power I could only get 18mph. That was some wind.
