Status: offline 		I have found that the urathane glue continues to seep out of the hole and you have to baby sit the stuff for about and hour. Once it starts to harden, water will not remove it. I use the same method but use Formula 560 canopy glue. It cleans up with water and holds very aggresively to the plastic hinges. If you doubt the strength, make up a test hinge and try to pull it apart. I also am sure to insert the hinge in the movable surface (either the aileron or elevator) all the way to the end of the knuckle. This puts the hinge pin approximately 1/16th into the elevator or aileron and places the rotation point behind the leading edge of the control surface. This eliminates binding when full deflection is desired.
I've used this method on 100" warbirds with 4.2 gas engines in the nose and have never had a hinge pull out. It's a lot easier than the urathane glue.

Status: offline 		Zap Hinge Glue is designed for glueing Robart hinges. You do not have to baby sit it and it the hinges can be handled in about 30 minutes. Once it is dry, you cannot pull the hinge out. If you drill the holes for your hinges properly there is no benefit to using glue that foams. It just makes a mess and you have to baby sit it. If you did not drill the holes properly, you should use an appropriate size brass tube to drill out the area and glue in a balsa dowel and then start over. Although foaming glue may fill the hole, there is no substitute for a correctly drilled, tight fitting hole.

Status: offline 		The width of the robart hinges is wider near the hinge point. After drilling a hole, I follow with "countersinking" with a small dremel cone shaped grinding stone. This makes a cleaner looking installation, and it has worked well for me. I was wondering how you guys do it ?

Status: offline 		Why not use Pacer "Hinge Glue" purpose designed for the job and water clean-up. It you use epoxy, remember it does NOT stick to the hinge material at all. It creates only a physical "socket" around the hinge. It works, but I prefer a simple clean-up material that sticks to the hinge.

Status: offline 		I'm certainly no expert chemist, however, I have used both the yellow wood glue and the Pacer hinge glue and can tell absolutely NO difference in how they work, look, smell, feel, set up, and (probably), taste! http://utopia.rcuniverse.com/micons/m15.gif

Status: offline 		If you don't like the CA hinges, these hinges are always a good alternative.
You'll probably want the "medium" size, for that plane.
I've never had a failure using them.

(On the other hand, I never had a failure with Klett style or CA hinges, either)
