I use CA hinges on virtually every plane i assemble and fly, BUT...... I only use one make, and thats the ones packaged and sold under the 'GreatPlanes' brand. They have never ever failed on me and they wick the cyano right into the hinge slot every time. I have heard from several people in my club who have used cyano hinges and have had them fail, only to find out they used medium cyano for the job instead of the super thin recommended. Also, it never fails to amaze me how many people try to use cyano hinges by putting glue onto the hinge and then try to quickly assemble the hinge/surface

If it isn't a greatplanes kit I'm putting together, the included hinges normally go right in the bin.
I think i remember seeing a video tutorial somewhere on this forum, that shows the correct method for using cyano hinges..... cant seem to find it now. I'm pretty sure there was one for the robart barbed type hinge as well, using the foaming polyurethane glue to install them. Used the method once to put the rudder on my Showtime 90, seemed to do the job very well
