I like the 15x6--10,200 stock muffler baffle removed. Almost as strong as my OS108 with the 15x6 prop (10,500).

What do you think about APC 14x8?
Or even a 13x10 APC?

If you want speed, APC 12x8 will get about 12500 rpm. Now that's about 100 mph if the plane is clean enough.

Ι will put this OS 91 FX in my Hangar 9 Corsair.
So it is a bit heavy.
But with a 12x8 will be a quick warbird,or i should go with a 13x8?
