    If you really want to learn about propellers, try making your own and running them. Since I run oddball Mercs (ex: Mark 78 on a Mark 55 tower) I have to build my own props; and it's been...educational. The latest, Prop #5 (photo), is working fairly well, but #4 self-destructed--not enough weld fillet. I actually have a video of its blades blowing off! Oh well...

    I beat the blades out of 1/8 stainless plate and weld them to a hub made from common pipe material. (Crude I know, but it works.) The hubs come from Surplus Supply.
