Hello,
Just bought my first four stroker, an O.S. 52. It's gonna haul a sig Fourstar Forty around the field in back of my house (or in front, depending on the wind direction ) I've owned a few two strokers, but I like little machines , so I went witha four this time. I progressed from little cox 049's (have you ever not flown on a day because you couldn't get the damn engine started, that was the norm for me) then a K&B 65 sporster, then a supertigre 75. Now I've got several projects on the table, so I have several engines that have never even been started. Grrrrr, so little building time!
Kurt
