The Cessna CR-3 was a follow on racing aircraft to the Cessna CR-2 that raced in the 1932 National Air Races.[1]

Development[edit]

The CR-3 was ordered by Air racer Johnny Livingston in response to the performance he saw when competing against the Cessna CR-2 in the 1932 National Air Races. The CR-2 was modified with a mid-wing design.

Design[edit]

The CR-3 was a mid-wing radial engined taildragger racer with manual retractable landing gear and a tail skid. The propeller was from a clipped wing Monocoupe racer #14. The tail surface was designed to be neutral, without downforce in flight. The elevators experienced significant vibration in test flights without the wing root fairings installed.

Operational history[edit]

The CR-3 lasted 61 days, winning every event it competed in.

  • Omaha Air Races, June 17, 1933 placed first.[2]
  • Competed in the Minneapolis Air Races, June 24, 1933 - First place
  • Competed in the Chicago American Air Race, July 1, 1933, the CR-2 first raced against CR-3 at the these races. The CR-3 won the Baby Ruth Trophy at a speed of 201.42 mph. It also set a world speed record for aircraft with engines of under 500 cubic inches capacity at 237.4 mph [3]
  • The Cessna CR-3 won the Aero Digest Trophy race on July 4, 1933.

En route to an airshow in August 1933, the CR-3 experienced a failure of both the tail skid and a landing gear weld that would not allow the gear to lock. Livingston bailed out over Columbus, Ohio and the CR-3 was destroyed.
