Guys, I finished installing the control surfaces on my Patty with the Robart Hinge Point Hinges, as I do not trust the CA hinges to last. Drill the hole where you want them to go, mix up some 5 minute or 15 minute epoxy, take a small rod (like a 2-56 pushrod or smaller) and stick the epoxy in and out of the hole with the rod, wipe off the excess, dap the "barbed" ends in a little epoxy, insert them into one side, repeat for the other side of the hinged area, press them together and let it set.

Running the rod in and out of the holes builds up epoxy on the inside of the hole, coating the hinge when inserted. Bend each hinge over and dap each side of the pivit it'self with vasoline, or lotion, this will prevent the epoxy from freezing up the hinge after it sets. After it sets up, flex the controls to make sure they will move freely, and scrap any excess buildup that might prevent it.

I do this on just about every model I build. The last 2 were the GP Pitts special, and the H9 Taylorcraft, both are ARFs, expensive, and I wouldn't want to loose either of them because of a hinge failure. If I didn't think thaat the would hold up, or stay in place, I sure wouldn't be putting them in these $1,200+ models! Just make sure you feel comfortable with having enough epoxy inside of where the hinges go, and you'll be fine.
