Graupner's 11" 3-blade is a 7 pitch
And Master Airscrew has a 7 and an 8.
APC doesn't offer a 3-blade under 13" dia. or around that, but they do offer a 10x6(4) and 11x6(4)
They might be worth trying. I've found 3s to work better than 2s in a some cases and better in a couple. So don't be afraid of extra blades in spite of the usual warnings from "experts", most of whom probably never saw a 3 except in the LHS, and most probably haven't seen them there as very few LHSs stock 'em.

BTW, MA doesn't have but one 5 pitch 3 blade out of their maybe 20 or 20 threes.
Most Graupner 3s are 7pitch or 8. I think they only have 1 six pitch three blade.
Finding a 5 might be hard. Although, since I just said that in public, someone is sure to post right away with links to dozens and dozens.

I think I bought a three bladed prop 11 inch prop from Mecoa that was around 6 pitch. I find that all props except Bolly and APC are flatter than advertised when checked on a pitch gauge. Something to think of when selecting a prop. Master airscrew props are ALWAYS flatter!
Are you using it on a Tigre 60?
