Several years before organizing Invincible Pictures, producer George Batcheller was releasing his product through Invincible's future "sister company" Chesterfield. In Batcheller's Sky Rider, an ill-tempered young man is cut off without a cent by his wealthy uncle, while the bulk of the estate goes to the clean-limbed aviator hero. Seeking revenge, the disinherited relative sabotages the hero's plane -- and when this fails, he arranges his uncle's kidnapping. The hero manages to foil the rat with the help of his newly-repaired aircraft, and with considerable ground assistance from his faithful dog (played by Rin-Tin-Tin wannabe Champion). The best scene in Sky Rider, set in an operating room-turned-torture chamber, seems to have sprung from a different film entirely.
