Default RE: Hinges, kinds and differences?

There are really 2-3 basic kinds that are most popular; CA Hinges, Hinge Points and Pinned Hinges.

I personally prefer Robart Hinge Points. They come in three different sizes based on the size of your application. I've never had a CA hinge fail, but then none of my planes have ever been more than a few years old. All of my .40 size planes have nothing but CA hinges and I've never had a problem. On planes .60 and over I would go with the hinge points. A Stinger .60 I just built has Robart hinge points in the ailerons since they are pretty long, but I still used ca hinges on the rudder and elevator. I personally wouldnt use pinned hinges. If you do ca hinges right, I feel they are safe. The robarts give added strength and longevity, but make sure you install them correctly. If you use the hinge points, I would also recommend you get the drill guide to make sure you get them straight.

For your OMP, CA Hinges would probably be fine though (IMHO).

Just in case you decise to go with the Robarts, take a look [link=http://www.airfieldmodels.com/information_source/how_to/construction/hinge_points/index.htm#technique_1]HERE[/link] for some installation info.

Good Luck

Thanks rik756, I just so happen to have one of those drill point guides. I won it as a pilot gift in a big bird event. Maybe this will give me the chance to use it.
