OS 55 AX first start and beginning of break in. Prop is a APC 11 X 8, OS #8 glow plug and Power Master 15% fuel. This was the first of four 16 ounce tanks. All though not shown RPM was alternated between four stroke and just breaking into two stroke every 10 to 15 seconds for tank #1. Tank #2 was alternating every 30 seconds. Tank #3 every 45 seconds and tank #4 every 60 seconds. Each tank RPM was increased until tank #4 high RPM was noted at 11,600 with room to spare. 10 minute cool down was observed between each tank and a heat gun was used to relieve TDC pinch prior to start ups. At this point the final break in will be in the air.
