does anyone make a quality 12x5 3blade nylon prop??

thanks Guys!

I have the WM 57" P-40 (yes yes I know WM? the kit had this problem and that problem and the tank split) I just wanted it to zip-around with. zip around? yeeha, the better pilots at the field told me it's a 100mph plane "LOL I guess". she has the OS Hyper 50 Heli engine with the big 60L carb and an oversize MDS stock type muffler. she turns an APC 11x8 peaked at 12.800, tuned for flight at 12.200+ (3 clicks lean).
she comes in really hot. one guy said she must touch down close to 30mph, I'm glad I was not landing her LOL. so I want to try a 12x5 3blade to help slow her down on the landings. plus, as you know "all War Birds use a 3 blader.

I fixed the Manual Retract problem, simple. the Belcrank Mounts flex badly. with CA I mount a hunk of Balsa 3/8" by 1/2" between the top of the mount (s) and the underside of the upper wing-top. the belcrank's screw treads threw the mount into the balsa stiffening the mount. problem gone, the retrack linkage works smooth and slick. got the JR 100oz servo for the job.

now wheres those Zeros at?
