Hi Brian,

Just took a quick measurement for you and the aluminum gear (not the tires) is 16" wide. Add the axles and that puts the tires just a bit further apart. The stock wheels are about 4" diameter and my aluminum gear is about 4.5" high so that puts the airplane 6.5" above the ground at the main gear. In my opinion this gives pretty good proportions for the Kadet, but I don't think there's any set rules, adjust to your tastes and I'm sure you will be fine. I have plenty of prop clearance (12" prop) so I could have gotten by with smaller wheels or shorter gear if I had to. I've brought it around pretty hard (fast taxi downwind and whipped it around at the end of the runway) and have had zero sideways tipping problems so I think 16" is plenty wide. But again, I'm sure you could vary all those dimensions by quite a bit and still have a perfectly great performing aircraft. My numbers are not optimized for anthing other than my visual tastes, and they seemed to work out pretty ok. No side-to-side tipping problems, plenty of prop clearance, no tendency to nose over, even in grass landings, and I like the proportions, so I'm happy. :-)

Regards,

Curt.
