I'm in the process of getting a new to me used WW 75" 3 blader dialed in for my Rotax Rans S-7S combo. A smaller dia then my usual 78" Prince 2 blade, for my winter flying. A few times I've moved a little snow with the Prince so a bit less dia will be helpful.
It didn't occur to me though, until I was perched on the edge of my ski ramp with the tail release still hooked and the engine idling, that I had better make real sure I didn't have a brain fart and set it up backasswards, so I shut down and held the Prince up next to it and determined FOR SURE that everything looked about right! As it was the snow was sticky, and I used every bit of my 400' of runway before finally getting unstuck. Testing a new prop on a sloped short strip on skis is not ideal but so far so good. Subsequent landings elsewhere showed the poor takeoff performance was indeed due to unusually sticky snow. But I still was able to determine that 1 more degree of pitch may be helpful, and in an easy hour, counting taking the cowling off and putting the tools away, made the adjustment. WW vaguely says "level" the prop while you adjust pitch, my scimitar blades made that problematic so I just eyeballed level more or less, and found that my chin was the same height as the blade tip. So I used that to determine the same height/arc of rotation of the blades as I adjusted each, otherwise I would have used a stick, anything to serve as a jig to keep it all consistent. FWIW, I'm at 16 degrees, different planes and engines but I guess similar aero demands of the propellers.
