Do you know if the horizontal stab and vertical fin are epoxyed into the fiberglass or into wood? Never had a fiberglass fuse before.
The Kyosho AT-6 has a very small wood stick at the top and bottom of the slot the stab goes in. The stab is built up balsa so there is wood epoxied to wood.
The fin is molded as part of the fuselage. There is a balsa stick that looks a lot like a popsicle stick that gets epoxied into the opening in the back of the fin. This gets slotted for the rudder hinges.
I do not know how other manufacturers do it.
