40 mm X 1.9 pitch ratio so 1.58" diameter X 3" pitch,,, kinda big !!
Not that big. Proboat uses a part number that does not follow the norm. It is a 1.6 inch dia x 2.5 inch avg total pitch. So the pitch ratio is 1.6, which they don't even say. Therefore 40.64 mm dia x 1.6 ratio for 63.5 mm avg total pitch in metric.
ok what prop can it be compare too so i know what it is iam a newbie on this stuff >???
ie : is it like a m447 >.........????
A - 40.64 mm dia x 1.6 ratio
would be between a - 640 and a - 642 (example 640 = 1.6 ratio X 40mm Dia.)
