I just bought a used Aircore 40 from a friend. He did not have the manual, and it needs some work. Can anyone tell me what typ of glue to use, the trailing edge of the wing came apart. Also how does the tray that the engine and servos mount on stay in the plane. Meaning the tray slides into the fuse on rails. is it glued in or rubberbanded? Is there a website that has pics of construction

Thanks .
