Question Propeller for 1/6 P-6E Hawk

Hi guys!
I'm finally getting to the end of my 1/6 scale Curtiss P-6E Hawk and I'm stuck on something neither me nor my friends could figure out: the propeller.
The original plane used a propeller with 3 blades and I'd like to keep that. My engine is quite unknown and the manual doesn't have info about 3-bladed props.
My local hobby shop seller told me he would use a 13x6 or 13x8 if I were to choose a 2-bladed prop.
I'm putting some pics of the engine and its manual.
Does anyone have an advice for the 3-bladed prop??
Thanks!

You have no rpm data. Without that it's hard to say. IIRC you normally come down an inch and a half in diameter or an inch in pitch when going from 2 bladed to 3. But based on what's on paper I don't believe the 13x6 to 13x8 suggested by the hobby shop.
When I went to a 3 bladed on an OS32SX I went to a 10x4 but that is a very high revving engine. It ran just as well as a 10x6 2 bladed.

Indeed I double checked and there is no rpm data... that sucks. The manual seems to suggest a 12x6 2 bladed for general use. I think I'll go either with that or go down an inch in diameter and take a 3 bladed 11x6.

11x6 is what I'd try.

Drop one and add two to the pitch so 11x10

Hi!
Its a Skyward .80 engine (Made by Picco in Italy) and thus a suitable prop for a scale ww2 fighter is a 13x6 or 14x5 APC (Two blade of course).
3-blade props are not recommended as those gives less performance than 2-blad props for that model.
