when is ok to fly
One of the problems with electric flight is cooling the motor and batteries. Your flight time may be increased if you are flying in colder weather. Wind is a problem even in summer. Skis are a lot of fun as are floats. We fly at an altitude of 5000' and we do get a little snow but the entire club is entitled to the "All Weather Flyer" patch from AMA. Concern yourself more about wind than anything else.
