For the downward stop I thought the two lower pieces of the rotor and the blade holder would interfer with each other stopping the downward movement. The upward movement is controlled in the same way, but I have beveled the blade holders inside edge about 15*. I'm hoping that this won't put to much tension on the living hinge, what do you think?
Rich...That sounds pretty good. It is pretty much the way I have been doing it. Recently on a small gyro, I used some short pieces of carbon fiber tube attached to the bottom of the hub and extending beyond the hinge so that the flapping part was restricted from flapping down. I also control the upward flap with a beveled edge on the flapping part of the hinge. I think 15 degrees upward is plenty. Some of the other fellows may comment on this too.
