I've had two OS 52 four strokes, along with a Magnum 52 four stroke, a Mag 70 and now a Mag 91. The only engine of the bunch to give me trouble is the Mag 52. The OS 52 are and were sweet engines. I lost one, along with the plane, behind our flying field. It joined four other planes lost out there in the last few years. I am really hooked on both the OS and the Mag four strokes. I have another Mag 91 on back order, an OS 1.20 pumper, used, that I have yet to run, a Saito 45, and a Thunder Tiger 90 four stroke also used but yet to run by me. I rebuilt the Saito and it is sweet running. Yep, I'm hooked on four strokes.
