Matt, those 3-blade gasser props are indeed pretty heavy.
If you want, I think I have a couple of 20x12 PT electric CF props that I would be willing to donate if you want to try making a 3-blader. I noticed (and I'm sure you have seen) that for the woodie 3-bladers they use a phenolic disk in the hub and peg the blades. I don't know if this would work with the carbon e-props but if you want to give it a shot let me know. Probably not compatible with your protocol for sanding down the wood props, but maybe you're in the mood to try something new.
If you're going to Pocono I can bring them with me.
There's an idea. Thanks Bob, I'l take you up on your offer. Yes I'll be there.
Hopefully there's enough hub area to allow 4 bolt holes....for the life of me I don't get the reason why gas engine makers insist on 4-6 bolts to mount a prop. Not necessary for anything up to 100cc
