Hi!
Why pin them?? It looks terrible!
I have never in my 30 years in this sport/hobby lost a flyÃ*ng surface due to a hinge failing in the air.

You ought to fly the old clunker I have, then. Vibrates like an old Harley, you have to check every linkage, hinge, wheel collar and bolt at least every other flight, or something will surely fall off. I had to land the other day, the plane was acting squirrely. The hinges on the rudder had vibrated apart at the pin (Robart Hinge points, the large ones) and the only thing holding the rudder on was the top hinge and the linkage to the tailwheel, and the control rod. I had only replaced the hinges five flights previous to the failure. I wound up doubling the number of hinges (four to eight) and rubber mounted the engine (US-41). So far so good, but I've only flown the plane four times since then.

I used the large Sig flat hinges on the ailerons, didn't glue them, but used two pins per side, they're doing fine.
