so i am wondering what type of hinges to buy, building a super chipmunk with a gas motor, I have installed both nylon andfiber hinges and wondering if added pressure on the surfaces because of a big motor for that plane wich ones to install? has anybody heard of the fiber hinges pulling out vs the nylon ones with epoxy pulling out? I have read minnflyer's articals about flutter and hinging but still need help. Iwant a tight clearance between surfaces.the kit is a golberg chipmunk.

I really like the Robarts hinges and you can get a small hinge gap when installing. For extra insurance you can always cover the hindge gap.

I just wanted to be the third person in a row from Minnesota to post

I like CA hinges for just about everything, but most of my planes are 60 sized or smaller...

BTW I am a Elk River Senior High Graduate

The Goldberg Chipmunk isn't a very large plane. I've used CA hinges on everything up to a 1.20 without incident.

What size gas motor do you plan on using for the Chipmunk? It might be a tough fit in that cowl.

<span style="font-family: Comic Sans MS">i'm seeing a trend develop and need to break it. all you minnasota boys. i use the CA hinges and love them. i've never had a problem with them pulling out. i have started my switch over to the robart hinge points though; i think they're easier to get centered on the control surfaces. i have a hinge slotting tool and the little red marker thing from GP, but for some reason, i can't get the hinge slots perfect. the robart one clips on the wing and you drill a hole. kind of hard to mess that up. i used to use the nylon ones and drill holes through the top and bottom of the wing and surface and grind off tooth picks after poking them through and into the hinges instead of gluing them. i thought that was always going to be my nemesis, but i got away from them. the CAones are awesome and i'm starting to like the robart ones better.

if you can't pull it out by hand after gluing them in, they're not falling or slipping out. </span>

LOL!

I used to use CA hinges and never had a problem, even on a 1/3 scale model. I hate risking dripping CA or fuming the covering.

I use Robart hinges now and think they're more professional looking and easier to install. Drill a 1/8 hole and counter sink it a tad. Glue them in with gorilla glue and they don't come out...use epoxy and they might come out.

I agree with the comment on Gorilla glue.  It works.

I use the large scale Dubro Hinges. I like these because the hinge pin can be removed and the surface removed. Glue them in with Hinge Glue from Pacer Technologies.

so it sounds like im going with robart hinges now with the responses (thanks), Im installing a jba 15 cc gas motor in the chipmunk. I hope she will fit with some mods to the cowl.now the gorilla glue, wont it keep expanding out on to the covering or will it expand back into the hole?

Forth Minnesotan!

I've used the CA hinges on both of the Goldberg Chippys I built, but they both had 4-strokes. I think I would still use them with a 15cc gasser, but you can't go wrong with robarts. Just be sure to use the robart Jig for drilling the holes - that makes it much easier.

Kork, did I meet you when I visited the Elk River field?

PS. OUTSTANDING airplane!

 Hello minnflyer, I dont believe i did meet you, maybe next spring when all this snow melts! Do you still fly the chippy? 
 

I miss Elk River, nice city. Where is there a field there? I wasn't aware of one.

It will be July before all this snow melts, holy cow!

No matter what hinges you install ad a couple extra and pin them with toothpicks or straight pins then use a 1/4" hole punch to make some patches from the covering you are using, assuming you are covering.

They have a very nice field off of Twin lakes Ave that is only about a mile from my step-daughter's house. I was invited to fly there oncve last summer and I thought, "This is great! Now I can bring a plane when my wife wants to spend the weekend with her daughter!"

Then later I was told, rather unceremoniously, that I would have to join the club if I ever wanted to fly there again.

Well, I didn't think it was worth taking advantage of such a generous offer to have a place to fly two or three weekends a year, so I'll pass

Dealing with Clubs can be interesting.</p>

Yea, some of these guys are from that club you took me to Robbie. Too many rules for me!

And no, I don't have the Chippy anymore. It got war weary so I handed it down to a deserving rookie (Who can now fly the pants off me!)

Say Hi to Al Lerberg for me and be sure to come down to the TCRC auction this February!

Depends on the surface being hinged, I like hinge pins and the flat. I don't like CA hinges, I have used them but I don't like them. No problem with them at all, just one of those personal things.
