Contra Prop Balancing???
I have yet to do this but I want to shape the tips on my blades. I haven't done it because I'm not sure how to balance the rear blade with the large opening. How have you done it and if you have pics, please share.
My idea was to have an insert 3D printed for the rear prop, but if it's like some of my other ideas I doubt it'll happen before the Worlds.
