I was flying above a viaduct across a valley yesterday and, although it was breezy, didn't cause me any concern; that is, until I got the 25% battery remaining warning & tried to return! I was at about 28m high and when I push the stick forward... nothing happened, it made no forward movement at all! I quickly realised that the high wind warnings I'd been getting meant exactly that! So, a quick switch over to Sports mode sorted that - nose down, no more than 1/2 stick forward, and back it came - no problem!
