hi to all, I need propeller drawing ( in dwg or similar Cad format); I want make custom plastic propeller on CNC milling machine from PVC or PP. I need suitable propeller for light canoe, trolling motor ~ 180W - 250W; I prefer diameter ~6", 3wing and pitch ~5". I can scale propeller diameter end extension or compress pitch, but I can't change form of wing. I find simply 3 wing propeller drawing, but I need high efficiency form, using by electric trolling motors.
regards
