I would like to get some proper pinned hinges (with the permanent pins) for this plane. The plane has a 72" wingspan and large control surfaces. I will probably fly it mildly, but it has the potential for 3D/pattern. Tower Hobbies has medium sized pinned hinges (I think by hobbico) but they do not show a heavy duty, except for the cotter pin variety which I don't want to mess with. Hope someone can suggest a good, decent sized pinned hinge for this plane, and a vendor to get them from. Thanks for any help.
