RE: savage top speed?
I just ran my Savage and my radar says 35MPH. It is totally stock with about 1/2 gallon ran through it. I think it'll go a little bit faster when it gets some more time on the engine and more tuned(running on the rich side), but not much. I have no interest in changing the gearing to make it go faster. If I wanted fast, i would have kept my Traxxas Jato that can't go through grass and spun out all the time.
The Savage will, however, wheelie all the time on grass and some of the time on pavement. This thing is awesome and it does exactly what I bought it for. I just need to quiet it down a bit. I've read that the XTM pipe is the way to go in that department.
By the way, for others out there who just got a Savage. Be patient, the power will come! It took almost a half gallon to wheelie and shift properly. I rarely touch the adjustments and this thing runs awesome!
Hope this helps!
