Which is better for jets where torque and speed are an issue
robart hinge points or cloth (CA) hinges, or flat plastic hinges not to mention Hayes polypropylene hinges?

I've never used the cloth hinges on anything big, much less a jet. I would not feel right as I can not convince myself that the CA has penetrated deep enough. I use the biggest size Robarts and use reasonably hard balsa for them to go into. Then I drill the hole such that I can hardly get them in and the barbs make it such that I may not even need adhesive. Then I take a hypodermic needle, rip out the needle and drill the end out, fill with long cure epoxy and put a lot in each hole. I add a drop of oil to each hinge at the rotation point and insert. Then stand the plane up or what ever so that the epoxy pools around the hinge point/trailing edge interface creating a kind of epoxy washer that locks the whole deal in. Let it cure and break it loose. Never had a single hinge come loose this way. Eddie does a similar set up but uses that new polyurethane adhesive that expands. He has had great luck with that and it is easier, but I like my way. Habit I guess.

Your "poll" did not include the Hayes polypropylene hinges which are also worthy of consideration. My Bandit elevators and ailerons use them for hinges and the Hayes hingges would definitely get my vote if there was a choice.

Robart hinge-points all the way for me ( wherer applicable ) ... i also love the gorilla glue method of securing these ..

great RCU write up here !
