The Cowboy Ace (1921)

Returning from her eastern school to her father's ranch, Ethel Filson meets and falls in love with Bill Gaston. She learns that Red Bush badly needs the $1,000 in a roundup contest and persuades Bill to allow Red to win. Red later returns the favor by using his airplane to help Bill find Ethel, who has been kidnapped by Snake Bullard. Bill punishes Snake, and all hands agree that Red's purchase of his airplane with his prize money was "a good buy."
