Just a quick recap what has been learned in the memory of the AVI@TOR 02 airframe.
Quit while you're ahead. Having the wing broke and fall of mid flight due to material fatigue is only amusing for so long. Once you know what kind of stress the airframe is going to be subjected to, reinforce it.
Also, physics works. Using ailerons as flaps changes the behavior of the plane. Don't forget to use the elevator to compensate for the shift in plane's Center of gravity.
That and the field test are fun! Hope for many more.
