Prop Size for OS 91FS Four Storke on H9 P51
I just finished the Hangar 9 P51 60 size with an OS 91FS Four Stroke. Can anyone suggest what would an ideal prop be for this setup. Any help would be appreciated.

I've got an APC 15-6 on a Bearcat 9.5lbs, Corsair 10lbs. and on a Sea Fury 12lbs all with flaps. The At-6 without flaps at 8.5lbs is better with a Graupner wide blade 14-7. The 15-6 pulls better but has less speed still they fly well at 3/4 throttle. The At-6 is fast and the 14-7 wide blade Graupner acts as a brake when slowing for landing. All the planes have OS 91 4-strokes.

Thanks guys for the quick reply. Sounds like the 15x6 is the way to go. Will give the 15X6 and also 13.5X8 and see how that goes.
