This is my first nitro, so tuning in itself can be a little challenging. Think I got a good tune now. Any leaner and it bogs down, any richer and it smokes a lot more with less power. Plus it idles good, so I think i'm ready for the PS. I actually got so mad when I couldn't start it that I threw it in the air...as high as I could. That was how I broke the gas tank mounts. Hopefully i will get the hang of it. Will post pictures up, and how it's working when it gets here. Tower says that a partial shipment has been made. But nothing is listed as to what got out...hmm...
