Being a bit lousy with my money, I mixed up batch of 25% nitro and 10% coolpower MV oil and I must say I was very surprised at the drop in performance. On the 19x11 I dropped from about 7.5K rpm to about 7.2K rpm, I was hitting full power much more often and the plane looked a little tired compared to how it had been running.

I only ran 3 tanks so the mixture could probably be tweaked a bit more, but it also seemed to be a bit thirstier as the tank had less left in it when the timer went off compared to the 30%15% brew. I'm at about 1500ft ASL

I'm happy to experiment a little now, as I'm enjoying the stick time although I don't remember this engine sucking down the fuel like this before. The 600cc tank is nearly disappearing in the same time as the 360cc tank I used to have fitted.
