Hi Rick, good question... I used to think that the longer arms made for a more stable quad. This is, or can be true. What I have found is that the longer arms make for a slower response by the controller so things can seem smoother. The size is easier to see as well. In the wind the longer arm quads seem to get batted around more than the shorter arm quads due to larger overall area.

The quad I used in the video on this thread is now cut down to 20" motor to motor (diagonal) from 29" I converted it to fit in my Nanuk case. It is still really smooth. So to answer your question anywhere in this range would work.
