Ive had a XS flux for over a year and a half now. I started with a 2 cell battery and it was somewhat drivable. I Had it sitting on the shelf for about a year and I decided to mess around with it. I bought a 3 cell(I know) and traxxas wheelie bar that I modified. Well lets just say I cannot give it any throttle without it flipping. I was wondering what upgrades I should get? My goal is just to make it stupid fast. I read about the 2.2 tires and the traxxas 2075 servo. I will get the right wheelie bar. What do you recommend? The truck is stock right now.
