Back Kellett K-3

Kellett K-3

The K-3 was an improvement on the K-2. The most significant change was the substitution of a Kinner C-5, 210hp engine for the Continental A-70, 165hp plant. The Kinner boasted 210hp at 1900 rpm. The weight of the engine was reported "under 190kg." The low weight-to-horsepower ratio was somewhat in favor of the Kinner. The K-3 used an 2.69m propeller. Optional items were a "coupe top" and a safety nose skid which protected the propeller in case of a noseup.

The horizontal tail plan form was changed for a more pleasing rounded shape on the elevators and stabilizer.

Records indicate that six were built. Two K-2s were modified to K-3s. One went to the South Pole with Admiral Byrd. This was donated by the Pep Boys of auto parts stores fame. It was N 12615. Two were sold to Japan. Standard equipment was: adjustable metal propeller, Heywood air starter, navigation lights and "Hotshot" (dry) battery.
