1975 OS MAX 15 RC

Ian, that's my all time favorite, sweetest running OS I ever used. My dad had a fairly large styrofoam full bodied Cessna 150 that was powered by this jewel. It would run ALL DAY LONG and never ever skip a beat. We would run that plane virtually 30 min at a time as soon as it landed, it was refueled and put back up. Mine is sitting in a cabinet and has low compression. I pick it up from time to time and give it a few flips. It just reminds me of the great times my dad and I spent flying it. Why this was discontinued is beyond me. While the newer .15's were more powerful, these were a perfect match for both r/c and also control line planes as they were a terrific running engine. Ken
