The first development of the company was the project of a three-engine transport aircraft. The prototype aircraft, designated XM-1 and registration number X3321, flew for the first time in late 1927.
It was an all-metal high-wing aircraft equipped with three Ryan engines (a copy of the German Siemens-Halske Sh 12) with 125 hp. The passenger cabin was designed for six people, but after a slight transformation it was possible to accommodate seven using the co-pilot’s seat.
This aircraft, built from steel and duralumin, was advertised by the company as being resistant to fire and the whims of the weather and even to damage (crash-proof).
After several months of testing, the aircraft was converted into the TM-1 (changing the registration number to N5728). In this form, the plane took off in June 1928 powered by Siemens-Halske engines.
The Super TM-1 had Ryan-Siemens wing engines and a Wright J-5c in the nose position.
Thanks to good publicity, even before the end of testing, a contract was awarded for the production of 16 such aircraft for Beacon Airways.
However, the company soon began to experience serious financial difficulties that prevented the implementation of these plans. The only copy of the aircraft made only a few advertising flights, and then, was converted into a single engine and sold to Mexico. The SE-1 designation showing the largest change to date, into a single-engine configuration.
The type was developed into the Solar MS-1.
