RE: U-Can-Do 3d 46?
It really depends on how you’re going to build the plane. If your going to use standard servos and an engine that's within the recommended size range, the stock CA hinges and thin CA works fine. If your planning to use high torque servos and a big engine, then I would recommend some Robart hinge points and gluing them with epoxy or maybe polyurethane glue.
