Thank you. The reason I asked is because of this prop I found for sale supposedly was on a hapi engine.
it says 53x36. wasn't sure if it would work.

Props are sized according to airframe / engine combination... The propmaker and in-service results are the final authorities in the prop selection process...

That prop has too much pitch and not enough diameter.
