I exchanged a few emails with Powerfin, on the possibility of using a two-blade propeller on my KF. (After the current problems are ironed out)
They recommend at least a 67" prop sacrificing some climb performance, 70" for a good climb/cruise balance.
I doubt I can accommodate a 70" prop without installing larger tires and/or reversing the HKS reduction unit from bottom to top layouts. (And I’d rather do neither.)
Until I get to the airport and take some measurements - What is the maximum prop size for a vanilla Model IV that still gives a good/safe ground clearance?
I will be operating from both paved and grass runways, but not from unprepared fields.
Thanks,
Roberto.
