Break it in on a 14x8, or a 15x6 is ok too. What fuel are you running? I start and run them at about 1/3 to half throttle, with the glow ign off, REALLY rich till I get oil out the 8in breather line. After that set the needles, and keep the hi speed needle a little rich, and fly it! The days of running and running an engine, before flight, are really gone. after the first gallon or so start to lean it out on the top end, and fly the wings off it. Check valve lash after about 5 gallons. NEVER run it lean!!!

I run mine on an Ultra Stick 60, 15x6 prop, and Cool Power 15%. It will hover at just under half throttle, and climb strait up till out of sight. It was my first saito, since then I have gotten 5 more, I feel they are great little engine.
