RE: Rate My Truck
It only "needs" upgrading if YOU want to. It will run and work fine just as it is for a very long time.
Personally, I only upgrade stuff when it breaks or gives me a problem or I can see that the mod will make an obvious improvement to an aspect that is important to me. Like off-set RPM wheels, they give the Maxx notacably better stability.
I very seldom let other people's opinions dictate what I do to my RC's.
They're my rc's, I like them. If others don't then let them buy one of their own and do what they want to it is pretty much how I see it.
