Props
I remember from my A&P school days that the back is in front, and the face is in back. The teacher used to drill one of the other students on this. On the props that i've done they look very similar to the ones in the previous post. When I thin my blades I change the camber of the blade some, and I will thin the rear of the blade on the trailing edge. I'm using this set up on my Saito .72 with a 14x4, my HP.40 with a 11x4, and the 11x4 on a Webra .32 all with good results. I've tried other sizes on other engines with not so good of results. Tom
