Kirk:

My legs are longer than some, I'm 6' 4" tall. But at the same time they are exactly the right length to reach from the ground to my crotch. Haw.

Regarding the planes, the Twin-Air has plenty of room stock for 11" props on grass, the Duellist 2/40 is marginal on grass, but OK on a paved runway. No problem with the 10" props. The 2/60 has no clearance problem unless you really go wild on prop diameter.

Bill.
