I'm building a P40B 50 Arf from Hangar9 but I would like to use an O.S. 0.50 engine but don't know if it will be strong enough does anyone know if this works or will work?
I dunno, if it says 46 to 60 then I'd bet it's more of a 60 size bird and more is definately not less in that case. Then again I had a 90 in my world air P-51 that was 40 sized, so, it'll probably be ok.
