Do You Use Nylon Pinned Hinges

I was just wondering how many of you use nylon pinned hinges?
I recently had to re-hinge the elevator and rudder of my DP Ultimate. I have found that CA hinges tend to split after a period on surfaces that have a lot of throw (movement). Especially if you use the low grade hinges supplied with most kits. You also have to be careful not to set the surfaces to close together thus inhibiting throw range.
In any event, I used Robart Hinge Points on the rudder because the supporting stock was thick enough. On the elevator I used Dubro nylon hinges for the first time and loved them. When installed with the pin NOT imbedded in the surface it sets the gap perfectly for maximum throw. It is then very easy to seal the gap and have a full throw hinge that is bullet proof and will not ever break. A slight amount of more work than CA hinges, but I'm hooked.

I have used em, and I have used c a hinges too. I like em both in the right application. Though I tend to like c a hinges, easier to use. But pinned nylon hinges are hard to beat for strength.

Yepper, I use them. I recently tried Kletts Flexpoints and so far all is holding together very well. These are good for when you don;t have much wood to bite into.

I usually keep my planes around for quite a few years. I had quite a few CA hinge failures on the older planes and have since returned to the pinned hinges.

Nylon pinned hinges are only good IF you buy the quality ones and you install them properly. I find such hinges are not forgiving, CA hinges are and work well for acrobatic planes up to 90 sized.

As AQ500 stated, I keep some of my aerobats for quite a while. I have had CA hinges split on a couple of them. There is NOTHING worse or more aggravating than re-hinging a plane. CA hinges are obviously the easiest. But they will not go on any more of my planes that have extreme throws. For sport and pattern type flying were they don't get worked a lot, probably ok.

Take a piece of plastic, bend repeatedly, sooner or later it fails. Its not a matter of if, its a matter of when. Small throws on a Sunday flyer will get some miles. Large throws on a 3D with the activity of all the radical manuevers, will shorten the life of the solid plastic CA hinge. On another note, with pinned hinges and the freedom of movement they provide, the servos are now dedicating more torque to the movement of the control surface instead of fighting the resistance of bending solid matter as well. The CA hinge is thin, but add them all up and it is considerable. Joe
