1980 American Champion Super DecathlonSingle-Engine Piston Aircraft • CA, USA

This 1980 American Champion Super Decathlon, registered as N121WM, presents with remarkably low total time of just 635 hours on both the airframe and its Lycoming O-360 180 HP engine, with the propeller also showing 635 hours since new. The aircraft has been maintained as a VFR-equipped aerobatic platform with inverted oil and fuel systems, though the seller notes "very little aerobatics" have been performed. With a useful load of 645 pounds and two-seat configuration, this Super Decathlon has spent its life in careful private ownership.

The aircraft's history shows only two owners from new, with the current seller being the second owner...
