I was flying the super-flea twin yesterday (Sunday) in 10-15mph winds. Had no problem with it at all. I was very impressed with it's ability to handle winds. ( and yes, it was the same plane shown in the videos, it is his demonstrator. )
Also, the David, the designer had his super-fly out too! (Electric one) Handled winds even better.
I will be getting me one of the Super-flea twins!
Later!
