Well...
APC has something like a 13.5x13.5- maybe too much pitch unless it was cut down- maybe too much pitch anyway!
MAS has a variety of three blades-like a 14x9 or a 16x10 you could cut down...
Try measuring the clearance, then use Jett's prop recommendation and work down to your clearance
(-1 inch diameter= +1 inch pitch)
Ex: 15x8 = 14x9..............14x9 = 13x10, and so on
This should get you in the zone, but verify using a tach and Jett's numbers for your engine
At any rate, sounds like a lot of fun!
Oh yeah-Don't use a chicken stick! :>(
