Indeed those cars did die out. They do have a very strong following in small groups though. The problem was they were not really race cars, but commanded similar prices. Bashers would not pay those prices for something that on the surface looked the same as any other non-race road car from HoBao, Thunder Tiger etc. Plus there's a lack of understanding generally of 4-strokes in the car scene. It would have helped a lot if other manufacturers had jumped on it too and used the OS engines in their cars, but as far as I remember it was only ever Kyosho.
The real 4-stroke fans were all putting bigger engines into their race spec cars. One guy actually produced a kit for a while for the Associated RC10GT truck (Thumper RC). In that class the OS 26 was competitive with the 2-stroke .12s.
