Okay, so I've been told by two people to replace the CA hinges on my LT-40 all together (one of them failed last weekend). I'm looking at the Robart Hinge Points, as well as some Dubro nylon hinges. Can anyone tell me how those dubro nylon hinges are installed? I'm at a loss as to how they are fixed to the airplane. I'm assuming some sort of pin runs through them and secures on the other side, but please, someone clarify here. Also, regarding the Robart hinge points, so they are drilled into the horizontal stab and elevator itself, okay. But, I'm worried with all the slotting that's gone on for the two sets of CA hinges I've done will weaken the horizontal stab to the point where the Robarts might pull out or split the surface. Also, for a Kadet, should I use 1/8" or 3/16" width? I don't think that new CA's are going to work because there will already be two sets in there, and it's pretty tough to find the space between them to put new ones. Plus, I just run the risk of them failing again! So, I'm convinced to go with a tougher hinge, just please help me understand the installation process! Thanks so much! - Spool
