Well factory settings are way off from where I'm at on tuning, but getting the high speed needle set properly requires the Low speed needle be pretty close, when you adjust one it really effects the other one. Plus I had to change to a different fuel. It doesn't like the traxxas fuel at all. I guess when your playing with an engine that makes so much power your level of error gets smaller, LoL. I'm gonna try again tomorrow as I think the neighbors were tired of hearing what sounded like a chainsaw running around the neighborhood. haha This thing is LOUD!!!!
