My research has me leaning to a 108-2 with the Bobcat 180 conversion. Fixed pitch. VGs. Utility interior. Empty weight down around the factory numbers. I've had a 172A with the Franklin 220 like 172Heavy has. Identical numbers except we had slightly higher fuel burn. We always ran ROP though so that accounts for that. Nose heavy! Could use the nose fork bigger tire for sure.
I just don't want to go the Franklin engine way until it becomes a viable company again. Li'l Red Aero says there are no more cranks available.
All this in a Cessna Thread........sorry, sorry, sorry.
