You can find any of the variables with p=c(tan0),where p=pitch in
inches, c=the circumference of the circle that would made by a
revolution of the prop at the radius in question. 0=the angle of the
blade for a given pitch at the given radius. c=2(pi)r, r=the radius in
question. pi=3.l4l4 If you know basic algebra and trig, you can
fig about all you would need to know. Stan
