iN THE QUESTION e-maxx was part of the criteria along with spending the least amount of money. So although a slower cheaper truck (if there is one to compare) may increase run-time . I try to just answer his question as best as I can and not try to think for other people.

ps I agree with you about the e-maxx, I run mine as hard as I can almost all the time. Some people may do crawling or what ever though. I typically use 3300's in 6 minutes.

Here is another idea to increase runtime for no money, but it would take lots of labor. Try to liten the truck as much as you dare.
