I’m trying to redraw the drawings so that I’m building it of aluminum. I’m locking for drawings for the chair and other hardware such ass landinggearselector and speed selector . I’m hopeful and I’ve got a complete mechanical workshop at my work so it shouldnt be any problems to make the things thah I’m missing ‘ If there is any one that think that they can help me please let me know
