I was thinkin bout goin with a 3 blade prop with less pitch to throw more air. I am an airplane guy A&P ia & pp from my experience the more blades the better the climb out sacrificing speed though. ie. a 2 bladed bonanza with io550 wil have a higher cruise speed than a three or even four bladed with the same engine however because all that power is translated with a three or four blade the thrust is greater causing an increased climb out.

I'd also like to see this be a pusher it'd have much better motor security, consider "clouds fly". I tried to change it but it'd take moving the stand mounts. Bummer.

As for balancing the prop... it really needed it. I used an Allen wrench to balance mine. Sure a bit rudimentary but it worked. Just slid it on and set the blades horizontal and boom she was swinging. I removed a ton of the heavy blade before it was close enough to not move from the horizontal axis. I can hardly wait till snow here so I can blast some powder.
