The build quality was top notch. My only complaint were the cheap/wrong engine mounts and cheap/easily stripped control links. I don't remember if I glued the hinges other than the rudder which you have to do after notching the rear of the fuse for elevator joiner (1 piece elevator/1 servo). I also opened the notch for that joiner as it didn't allow full elevator travel. I insist you get 4/40 rods and ball links and suggest you get a heavier pull pull rudder setup, while not mandatory, will make you sleep better.
