Aeronca 7-AC Champion Giant Scale RC Plans – 141" WS, 40–50cc, 4-Channel Printed

Aeronca 7-AC Champion – Giant Scale RC Model Plans (141" Wingspan)

True-to-Life Scale, Unmatched Presence

The Aeronca 7-AC Champion is an American classic — and this giant-scale RC model captures it in stunning detail. With a massive 141-inch wingspan and over 2,800 square inches of wing area, this aircraft offers true scale flight, elegant handling, and visual impact that dominates the field. Designed for 40–50cc gas engines and 4-channel radio, this project is the centerpiece of any serious modeler’s hangar.
