Default RE: **WM Super Chipmunk prop size**
A lot of people consider a 14x6, or any size with similar load, to be ideal for the OS 91 four stroke
14x6, 13x8, and 12x11 would all put a similar load on the engine.
I don't know if the 12x11 would give the overall performance you need but in theory it would be fast.
