Thanks Michael

I use the Murnan method (prop stand) as listed on his website to break in my engines as well. However both the t9 .12 and .21 c9's that I have broken in I ended up running an additional 4 or 5 tanks at half throttle between 190 and 200 degrees before they felt like I wanted them to feel.
You will love the T9RC with the 2604 pipe, fuel miledge is very good as well.
