## Design and development

The Baby Great Lakes was designed by Barney Oldfield, and originally built by Richard Lane, to be a scaled-down homebuilt derivative of the Great Lakes Sport Trainer.[2]

The Baby Great Lakes is built using 136 ft (41.5 m) of steel tubing for the fuselage with aircraft fabric covering.[3] The wings use spruce spars. The aircraft can accommodate engines ranging from the Continental A-65 to the Volkswagen air-cooled engine.[4]
