I built mine in 97 or 98 and I used every stick of wood they gave me and never used any of my own. Hinges, I used all Du-Bro and never use the CA hinges. Like Piper says, each his own. I thought it was an outstanding kit and A great trainer, three people learned to fly with that plane. I did cut the ailerons down and made flaps, added A candy drop door and used an old OS 60. In A good stiff breeze it could fly backwards. Also made the wing A screw down instead of RBs. I still like flying the Masters when I get A chance.
