Champion Aircraft Corporation was formed in 1954 by Robert Brown.

Headquartered in Osceola, Wisconsin airport, it began production in 1954 of the 7EC design which it had purchased from Aeronca Aircraft Corporation.

Champion also developed and began production of the significantly upgraded follow-on to the 7-series, the 8KCAB Decathlon, as well as the twin-engined Lancer.

By the time Aeronca ceased production in 1951, they had advanced the design through the 7BCM, 7CCM, and 7DC, reaching the 7EC.

Though there was a great variety, all of the aircraft which Champion introduced were in one way or another related to the original Aeronca design.
