Did you train with an instructor? If so, he should have had you doing take-off's and landing approaches in as many different wind situations as possible before you solo'ed. The purpose, of course, is to get you to understand and react properly with changing wind conditions.

I've flown on days when the wind changed direction several times, and you have to react correctly to those wind changes.

As far as your "reverse any two leads" issue with the ESC - Motor connection, well, it always worked with me, that is for a three phase DC ESC control (brushless) config.

As far as the crash is concerned, you tried to lift the left wing? Using right aileron input I hope, as in trying to make a right turn, but perhaps to counter wind that was lifting the right wing?
