RE: SIG Komander
Also build one in '75 and used the just released Enya .40, which flew the plane with plenty of authority. It served me as both trainer and intermediate. No problems with landing gear. Also silk and dope.
An interesting aside is back then, one of the 3M spray adhesives was foam friendly and sheeting a foam core wing was a piece of cake with the spray adhesive. A wing would build up really fast, and they were strong albeit slightly heavier than a built up wing. The Kommander had a generous wing for a .40 size plane and with the wash out had good flight temperament.
