Following the test flying of a Doman-designed rotor on a modified Sikorsky R-6 (designated the LZ-1A by Doman) the company developed a five-seat helicopter to use the rotor. Little information is available on the LZ-2A other than it was developed into the larger eight-seat Doman LZ-4, the LZ-4 was the first helicopter designed completely by the company which indicates that the LZ-2A was perhaps a further development of the Sikorsky-based LZ-1. The LZ-2A Pelican was powered by a 2450NaN0 Franklin engine.
