hi ,
as ASP 52 engine is able to run 11*8, 12*6, does it also support 14*4 ?

I would be putting in a 13x4 wide prop on the ASP .52!! I have also read somewhere that the ASP .52 spins a 14x6 prop at 7000+ rpm though I do not know how true that is!! In my opinion, the correct prop for an ASP .52 is a 12x6 for pattern and 12.25x3.75 for 3D!! The max you can go for 3D is 13x4!!

i have tried 12.25*3.75, its too speedy on my YAK , dnt know why
can u suggest smthing for truly slow flight for 3D ?

Fly at half throttle !! Or make the fuel mixture a bit more rich!! You might be running it too lean! And finally try a APC 13x4W prop
