Rotary engine prop

[Oly]

Does anyone out there run with a Mazda 13B Rotary engine?  I have one in my canard Viggenite with a Ross 2:17 redrive and it runs great.  The prop is a 3 blade wood from Performance Propellers (68 x 73).  They don't seem to have a lot of chord to the blades.  Cruise is OK but T/O & climb could be much better.  Any prop experts out there that might have a better idea for a fixed pitch application?  How about 2 blade VS 3 blade?  I've been leaning heavily to the Prince 3 blade composite Q-tip prop (68 x 60).

Hi Oly, I am running a 13b in my long ez, ross redrive, and have used both 2 and 3 blade props, my preference was the Ivo magnum, but have gone back to 3 blade wood for CG. I reccomend the ground adjust Ivo if you have cg to spare. Also, I am looking to buy 2.13 gear set for Ross, any advice where to find? Thanks, Bob Mencl, N613NC

How many hours do you guys have on the rotary engines?

We out west are leaning ever toward Hertzler and Catto for better takeoff and better top speed on fixed pitch props.
