Why did you place the pivot point where it requires a counter balance? Could the pivot point be placed in the balance point of the wing (rather than the forward end) in order to eliminate or reduce the counter balance?
That is definitely something worth looking into. Moving the pivot point away from the center of mass of the wing helps give the aerodynamic forces more leverage, but it increases the inertia of the whole assembly. Moving it closer would lighten things up, but might not give the aerodynamic forces enough leverage to fight against the inertial forces. But the optimal point may be different than what I've got. I just modeled it after the design in the patent.
I’m guessing you used PLA, if so heat is definitely a bad idea! I’m would suggest a smaller layer height. say .10mm. Could also try printing the blades on their ends in one piece. I would use a good size raft to reduce the risk of the blade falling over mid print.
I truly appreciate your documentation effort here. Very well explained. Thank you
He shared very detailed information about making wind turbines very well.

Could you smooth out the wings by using a flame? Would it work better if they were?
I'd be too worried about destroying them. :-)
