I had to change the gear on my Impact due to impending failure that I discovered after a flight today, nope no crashes or hard landings... Anyway, I went to a Bolly Electric gear and now I have a clearance problem. Plane was singing along with a 22 in prop, now I"m restricted to about 20. Anybody know where I can get a 3 or 4 blade prop that will work with a Plettenberg prop adapter?
