Does anyone know what these things are for on the Sportcopter rotorhead?
My guess is they stop the blade teetering when stopped, but fling out of the way when rotating?

You are correct Sir .

Nice setup. My RAF has a sportcopter head as in the picture & I also have the blades.

Yes, I had a teeter stop on my RAF.

Wow, lucky guess :)
Has there ever been an incidence of them jamming in place and stopping the rotor from teetering? I suppose a pre-flight would identify any stiffness in the pivot.

Ron Menzie has a stick made from a broom handle and about 2 ft of foam insulation similar to what plumbers use on hot water line.
In preflight the stops are tipped up with this stick to clean and check the blades. You then tip down the stops. I am sure you would notice if there was a problem when you pre-rotate. Centrifical force throws them out.
