Prince aircraft will make you any size you want, they are not cheap however. Call him for details. www.princeaircraft.com. Also fuchs makes a 36x10, MSC 36x15, and bolly makes a 36x14.

$300- that's what
frankly on another note - why the low pitch
At this size I would want more pitch (and less rpm)
just me daydreamin
I am runnin a 30x14 (maybe they stretch the truth ) but terrific noise control and my engine pulls verticals easily with it.
for cruise - the throttle is waaaaaaaay back
full scale stuf turns much deeper pitches and on these big engines -I really think more pitch is desireable

Isn't it hard getting decent power out of a 2-stroke at the lower rpm, say 4500 or so? Also, if your idle is still at 1000-1200, a high pitch prop will still pull quite a bit.

I think I have a Xoar 36x12 for my Herbie280.

seriously - My 160J on JMB mufflers runs 5900 on the ground - 6600 in level flight and reliable idle (for landing )---- 800 +rpm setting - I checked it last weekend.
I have 32x10 paint stirrer- that rips just stirring the paint. The idle setting really surprised me - so I walked over and pluggen in the tach --
The 210's I have run - like to run around 5000-5500
