Sands,
I havnt used them yet, but, after the crash, did some research and discussed options with club members who also had problems with ca, (certain accident). hinges and have decided on Dubro pinned hinges.
There are several diferent sizes of these hinges I found what I believe to be the appropriate size for my application.
Seems theyll be an easy install too. Just make a slit a little larger than necessary to fit the hinge in, draw up some epoxy into a straw, pinch it flat, insert into slot and squeeze it out.
As I understand it, that part is optional, the next step is to drill in some dowells, (toothpicks) through the wing- stabilizer ect into the hinge and out the other side, though I am going to drill through the bottom and stop just short of comming through the top covering.
I have not used the Robarts you refered to either, I like the Dubros better. I think, they are more like a conventional hinge and have more surface to glue in.

Robb,
I hadnt considered the points you raised, you make a good case for using pinned hinges just because of the ca mess!

I built an Uproar 60 this fall and did one of my best covering jobs ever with transparent red and yellow. I then CA'd the hinges. Since the control surfaces were built-up, the CA fumes fogged the inside of the covering in places. This was enough to make one mad!

Damn ! I can understand the feeling. Damn! Damn! I'll take heed of this with see thru coverings.

Flap,
Thanks for the follow up feedback.

The 4* 120 only has 5 hinges in the stab.? I know that the 4* 60 has either 6 or 8 hinges?

4* 120 has 8 hinges in the elevator, thankfully, 3 were still hanging on.

Sands,

Yes, you definately screwed up, but it's not too late to use the hinges. This fix will be a lot easier than replacing them. Just epoxy them into the wing, then drill a tiny hole through the trailing edge and the hinge and epoxy a round toothpick into the hole and sand it flush when dry.

Mike,
Thanks for the alternative idea. I intend to use it since the current location of the hinge slots are aligned properly (see attached image) and to create new ones opens up a can of worms. I'm still bummed I made the mistake in the first place but your solution is quite viable. The only thing I am not clear on is how to get the epoxy into the hinge slots. I am sure you have an answer for this problem also and Thank you in advance for the time I see you take for the many questions on these threads. You are one of those people that makes this hobby great.
Thanks again. Ron

Flattery will get you everywhere... Keep talking!

Getting epoxy into the slots isn't too tough. You can smear it in with a stick (or your finger) and add a thin coat to the hinge. A better method is to feed the epoxy into a drinking straw, squeeze the end flat, insert the flat end into the slot, and add the epoxy A' LA Toothpaste Tube.

Either way you go, Make sure to wipe away any excess with alcohol before it sets so you don't have any big epoxy goobers in the gap.
