I probably stand alone, butInterestingly enough the very chagrinof this post is what I do (to a certain degree). To date I've never encountered any problems and all my surfaces are securely connected. I think what happens often times is the addition of <u>too muc</u><u>h</u> CA when someone tries to "set" a CA hinge in place, rather then using pins.
But honestly, I see nothing wrong with the approach; when done correctly.<br type="_moz" />

Hey Minn, I just read your article on CA hinges. I had skipped it for a long time because, well, you know, I already know everything
Unfortunately that is not true. You touched on something in there reguarding a "myth" that hinge gap causes flutter. That of course being the myth and the fact is that it does not. I have been for a long time a propegator of that myth and would be very interested in the article you elude to reguarding flutter. Perhaps you could call it "Flutter, Causes and Cures". Because knowing why it happens is worthless if you don't know how to eliminate it. Oh, and throttling back and slowing down are not options![>:]

I dont see it as a problem either,,I build 1/2a and very often (almost always) will take one of those slotted ca hinges and cut it in half....I will make sure its gonna fit where its supposed to, then take it back apart and glue one side...never had a problem with a hinge coming out yet, never pinned one either...I did once take a $3 foam glider plane from k-mart ,cut a few inches off the nose and stuck an .049 on it, finally got it balanced and used monocote hinges full length of the rudder/elevator and on the 2nd flight the flutter got so bad the thing literally exploded, the whole tail floated down in 50 pieces......Rog

I bought one of the other ARF's,this company sells, just to see what they are all about. I think the photo may just be an assembly picture. The Stylus uses the same hinges and none of them were glued. I have the same picture to show how to install them, although wrong.

Then you're not flying fast enough. CA hinges work great if you monocote the hinge line. Otherwise CA hinges will shear - at least that's been my experience.

I think it's a woman, the bulge in the sweatshirt makes it seem like ta-ta's. Plus, the reflection shows a pink shirt on poking out. Or a very secure man wearing pink that has a large tool shed and likes his nails long to pick out the bad CA clumps from the hinge line.

In certain situations you would actually need to install the hinges in this fashion, one half at a time. If you have a built up stabs, Kadet senior, gliders, and old time airplanes, and cut a slot for the hinge, you want to make sure that the hinge is installed half way and not push all the way through the stick. Use thin CA to glue the hinge in. Being from old school flying and building, I would then pin in all of my control surfaces hinges. I would drill a 1/16 " hole through the hinge and control surface, dip a flat style tooth pick in some carpenters glue and shove it through the hole, let it dry, and trim it off using finger nail clippers.

Heavy Metal Thunder, with all due respect, there is NEVER a time when that is a correct proceedure.

It was designed by a double agent and planted into the Russian fighter design programs during the cold war... You might not be able to find any other info about it...ITS THAT SECRET!
