Hi Salty. I think that most of us have had models that we are sorry that we sold or otherwise lost. I know I have. My Goldberg Cub with Enya 80-4C was one of them. I have since bought other Cubs and other Enya 80 & 604C engines, but it isn't quite the same. Perhaps it was also that moment in the time of our lives that made a significant contribution to the experience?

Thanks for the report on the OS.48 in the Rascal 40 airframe. I wouldn't have thought that there would be that much of a difference in power between the OS FS-48 and the Magnum .52 four-stroke, but there is a generational difference between the OS FS-48 and FS-52, so maybe Magnum copied that too. It would account for the significant difference in power that you are reporting. I've owned the Magnum .52 and the .61 and couldn't really see much of a difference between the two. Might have just been my samples. Who knows? Anyway, theoretically at least, one would think that the .61 would handle more prop without protest than the .52. Theoretically. 8&gt
