Pusher props for ls ys 61-s

Hey guys, I just posted elsewhere in the forum about this. I have no idea where im going to find props for this engine I just purchased. Im told the long stroke ys 61-s likes to turn larger props at less rpm. Any ideas where I might be able to find a 12x10 or 11x12 pusher? Clearance is an issue. Its going on the back of an old combat models f16. Id like to keep diameter to a minimum with as high a pitch as the motor can handle.

Ive heard of guys re-pitching apc's and id be willing to give that a go if I knew where to start or someone who was willing to do it.

pusher prop

I just purchased an old balsa usa jet at auction this weekend. Obviously the same concerns. Using an older OS 61, very strong engine. I used 12x6 props on it before. Largest pusher I found was 11x7, purchased this morning from local hobby store. I had already ordered one from tower-didn't see any bigger there. I did also order from tower a 10x6 three blade. Figure will get more clearance and that third blade will drag the engine more. I am actually concerned may need a smaller 3 blade. Will find out as soon as it warms up around here.
