Hey guys, I have recently installed an FPE 2.4 engine in my Hanger 9 P-51 Mustang. The fit was good but I would very much like to use a 4 blade prop to look more scale. I emailed First Place Engines but they have not responded to my question. I just need advice on the size 4 blade prop I can run on that engine. Anybody have any input ??
Thanks

Anybody even make a four blade that is usable and not just for static display?

Like you can tell if its a 2 bld or a 4bld when your flying??????? The 4 bld is for static use only, a 2 bld will out pull it.

Yes, they make 4 blade props but for your airplane, the 2 blade prop will be most efficient for flying. Its just that simple. You don't have a lot of power there to be turning 4 blades. To get a 4 blade prop up to a useable, efficient RPM, it will either have to be a very small diameter or low pitch prop ... or both. To me, that spells a crash waiting for a place to happen. You can probably find a prop combination that will cruise fairly well, but take off performance will be severely lacking.

Make a nice static prop for non-flying ... and use the 2 blade in the air. Sorry if this answer isn't what you want to hear.
