O.S. FS70surpass II

I would like to know what everyone is getting for rpms with this engine with 13 to 14x6 props? Having some trouble deciding on a prop for a 40 size cap 580. Any help appreciated.

RE: O.S. FS70surpass II

APC 13x6 should get 10500 rpm, 7.5 lb. thrust
APC 14x4W should get 10000 rpm, 8 lb. thrust

My friend has a Kyosho Cap 231 .40 size, and when he switched from APC 13x6 to APC 14x4W, it puts a smile on his face.
