I think that is about only half enough battery for a fast rusty. I'd recommend getting at least a 4000 or whatever will fit in the battery box (4000-5000 mah)
so you are saying that a higher mah= faster speeds? How is this true?
I didn't say that , but it is true to a point. Given two batteries that are from the same manufacturer or family the higher capacity battery will hold voltage better while under a load close to it's max. That voltage will make the vehicle faster. If neither battery were being operated close to their max currents (like in a regular xl-5 rustler) then there may not be a noticeable difference in speeds.
The reason I recommended twice as much battery was for it's ability to deliver twice the current in your vxl. The biggest difference in both cases is going to be runtime (directly related to capacity mah)
