My issue was that I think it's very important to have the handle as tight a fit as possible. When I got one that fit my hand correctly (probably an 75 or 80mm) the gap between the face plates let my skin get forced up into the inner edges. It could have been fixed by gluing some balsa in between the sides to fill it up and extend the forward projections, but it wasn't mine so mods weren't possible. It's just a matter of preference, I think, but the "tight on the fingers" thing is one of the thousands of tricks Ted clued me into. You can make a lot of minor corrections by small changes in the tenseness of the finger muscles.

HI Brett
You are exactly correct, having the handle be a tight fit is absolutely critical , if you want to fly a consistently good pattern. With a handle that your hand can slide around in the plane will not be steady, and corner exits will suffer, as well as round track.
Plus we all know how much a 1\16 inch adjustment on one leg of the handle will make a huge difference in the "feel" of the handle in relationship to the plane.
If you have a handle that is not a tight fit on your hand, you can, and most likely will ,pick it up differently many times, this results in a handle that feels like the adjustment has been changed ,just by your hand being closer to the top or bottom. I won't even go into the problems that high winds will have on a handle that is too large.
