Gentlemen,

Is there a chart or table to convert a 2 blade to a 4 blade prop.

I have a dle 55 in a top flite p-51 witha zoar 23/8.

Any suggestions?

Chris,
Get in touch with these guys for some good technical advice and some great propellers. The fliers at my field use a lot of them for multiblades. Dan.

Chris forget it, fly it with a 2 blade, effiency is out the window with 4 blades and they cost a couple hundred bucks because they need to be pitch adjustable. A DA 85 in that plane will only turn a 23in. variable pitch prop with 4 blades, go figure. Leroy

You should be able to run an 18x10 to 20x10, depending on your choice of silencer.

That engine is suppose to be broke in with a 22-8 prop, then you use a 22-10 or a 23-8 and let R.P.M. determine which one to use, Leroy
