I've looked everywhere I can think even googled it, where can I get a 11/5 3 blade.
Thanks

Not a 11/5 but I am not sure an 11/7 is really a 7in pitch.

The Master Airscrew checks out at around 5.5 on a pitch guage.  MA appears to use the chord line of the airfoil for pitch, not the flat on bottom of the airfoil.

Thanks that's good to know I was going to order a 12X4.5 from Steve Wilks and cut it down as the one from Zinger kinda looks heavy. Anyway what I'm doing is mounting a LA 46 upright with with wing mounted landing gear so ground clearence may be an issue.
Thanks

Before we discovered Bolly props (and their adjustability) the "pipe players" "carved" their own custom props from existing stock. We scraped the trailing edge of the backs of the prop blades with the sharp edge of a straight cut piece of glass, or a # 26 Xacto knife. Do this until the 5 inch pitch measures 4.5, 4.75 or whatever...Then refinish.

FWIW

Thanks Ward it may be about time I learned how to do that, how did you know what the pitch was? Is this what you used?
