Default RE: Flawless maiden

ORIGINAL: WS

Try a 14 x 10 APC. My TF Corsair went ~120 MPH with that prop on an OS 120 FS. Mind you, it's a bit smaller than the KMP, but 7 pitch would definitely seem to be the speed problem.
What kind of rpms are you getting with that OS120? With a 10 pitch prop and assuming 100% efficiency, it would have to be turning 12,672 rpm in the air to get to 120mph...
