Erik,

Actually, YES. Here is a pic of my Insight with a 17x8 apc. The second pic shows a measured distance from ground to prop shaft of approx. 12-1/4" with the tailwheel on the ground. The third pic shows a measured distance of approx. 11" with the stab level (note the mini soccer ball holding the rear of the fuse up). This should allow for a 19" to 20" prop with ease.

p.s. I need to get dimensions for the new Plettenburg and I will gladly do a layout in 3D if it will help in your planning and building.
