RE: OK Cub History
No Herkimer did not make an RC engine as such in the 049 size OK 049 engines were made for CL and FF. I was building and flying RC in the early 50's in the DeBolt Live Wire trainer. The 049. would fly it but was marginal. Got lots of flights with them but OK started offering the 014 engine and flying the Live Wire was much better. They would wear out quite fast and had to be replaced. I had two or three worn out ones in my flight box and when they quit running well would swap pistons from the old ones till I got a bit more compression and flew a while longer before buying a new one. They were not to difficult to start if you primed them properly. Boy oh Boy those were the fun days. If you got a succesful flight or two in a days outing it was fantastic. Still flying RC after 55 years and love every minuite of it.
