It's a BL-1770x1450 cut down to 1730 mm.Looks like the BL 1750 prop is it?
I am using a BL 1770 x 1450, it is a very quiet prop.It's a BL-1770x1450 cut down to 1730 mm.
So it's the same size as the standard prop - I didn't dare get it closer to the keel.
But with larger area - I guess that's alright since it's on a 914 engine.
Sometime when it's convenient, I have to have it noise tested.
