I look at this and think the answer is pretty straight forward, fly the thing previous to flying in a public atmosphere. I certainly would want to know that the repaired ornew plane flew right, before trying it at an event with all sorts of people around who may have no idea that the airplane coming at them is out of control.

I have no problem with the indoor type airplanes being exempt; however, who makes the decision about where the cut-off is and what it is?
