The Alon A-2 and A-2A Aircoupes were much improved upon models of the original Ercoupe which differed from it in several ways. The Alons featured a sliding canopy, a more powerful 90hp (up from 75) Continental engine, separate bucket seats and a much improved instrument panel.
Over the period of production (1964-1967) Alon produced 245 A2s, with peak production of 137 in 1966. The last 25 A2s produced by Alon had spring steel landing gear in the place oleo struts.
Another aircraft produced by Alon (although only a single example was ever built) was the A4. The A4 was a low wing 4 place monoplane of aluminum construction powered by a single 150hp Lycoming engine. By all accounts it was a very good airplane, but it was not to go into production before the closure of Alon.
Production of the A2 ceased in September of 1967, and on 9 October of that year, Alon was purchased by the Mooney Aircraft Company of Kerrville, Texas.
