RE: Percentage of Nitro in the Fuel
I fly a UCANDO .60 size with a Saito 100 on it. I started using 10% nitro then switched to 30% Wildcat just to try it. There was a noticable increase in power (like I took a pound off the plane) and the idle was smoother. Needle settings remained the same but I had to lower the idle a few clicks. I didn't notice any change in fuel consumption.
Don't get me wrong, this setup didn't need any more power but it made it that much better punching out of a bad 3-D move.
One other advantage is that I don't need to install a smoke system-with the extra oil, 30% has it built in!
