As I remember it, World Engines was the importer and distributor of both OS engines and Super Tigre. They were inexpensive engines at this time.

Great Planes offered to place full page, color ads in the model magazines if both manufacturers would jump to them as a distributor. World Engines didn't want to do the ads so OS and ST moved. Of course, the price of advertising was passed on to us, the customer, as higher prices. To their credit, Great Planes has kept a good stock of parts, better then World Engines, and has good service.

After losing OS & ST, World Engines got ST, and I think it was a brother of the owner, to manufacture the Como. This was obviously a relabeled Super Tigre, who probably sold more engines than did OS at the time. Great Planes couldn't have the same engine with a different name sold cheaper so they brought a law suit. I also understand they stopped a shipment of Comos at the port of entry. This killed World Engines' attempt to keep somewhat of a Super Tigre.

John Maloney, World Engines owner, then went to China and had the Awesome Speed and Power (ASP) engines made. These were to be his low end engines. His next engine was the Tiger Shark, his mid range. He talked them into a new factory to build his top line engine, the GMS. Before this all came to fruition, Maloney died and Jim Goad of Indy RC bought WE from the widow. Then he died and Circus Hobbies/Horizon Hobby bought in and used Indy for their mail order retail store before changing the name the Horizon.

At least, that is how I understand what happened.
