I've been running an 11x6 on my Thunder Tiger 46. If I wanted to switch over to a three blade for a more scale look, what would be comparable? I have heard that you should drop one number on either the diameter or the pitch, but I'm not seeing any 10x6 three blades or 11x5 three blades. Would you go with a 10x5 or a 9x7 that Master Airscrew makes?

I'd run a 10-7. http://www3.towerhobbies.com/cgi-bin...?&I=LXAA34&P=7

If you've been running an 11x6, you'd get the same performance from a 10x6 3-blade

I'd try the 10x5 and the 10x7 and see if either works on your plane.

10x7 3-blade

GWS do a 10x6 I think it is OK for IC but check first before using.

Ya' might consider a Graupner 3-blade. They make MANY sizes and is an EXCELLENT performance prop. Probly' have to mail order it though.

APC doesn't seem to be big into 3-blades.

Master Airscrew is OK and they have many 3-blades to choose from, but they're just not as good a prop for performance IMO. The MAS will take a beating though!

Since a Thunder Tiger looks like a Cessna and most Cessnas have 2 blade props what is your "scale" thinking? What plane are you emulating?

The 3 blade prop is for a Thunder Tiger brand engine. The plane is a B-25.

Ahhhhhh, now THAT makes sense.
