U CAN DO with a Moki 1.8 and tined pipe!!!....?
1.8 on a UCD .90? That is an incredibly innovative idea. I once put an ultralight engine with 48 x 15 prop on a Great Planes Gee Bee. The SOB was EXTREMELY fast, but difficult to taxi, takeoff and land. Makes you an honest pilot for sure!
Good luck with your "U-Can-Destroy" 3D.
