* I completely went against recommended usage when my new to me X-Maxx ESC bricked when I tried to update the firmware that the Traxxas app told me to do. After Traxxas courteously offered to do nothing I looked around the shop and saw this sitting on the bench. I knew it was wrong but I wanted to try out the X-maxx and at least gently rip around a little bit. At first I was pretty disappointed but figured "duh, this is way too small for that truck" until I realized i was being limited by the ESC because I needed to swap a motor lead. It was limiting my speed forward because it thought i was going in reverse. Once I swapped a motor lead I was blown away, this ESC had that big truck spinning tires and pulling wheelies left and right! I didn't even run a full pack through because again, not the right tool for the job, but I definitely have no fear about it lasting a very long time in the 1/10 scale it resides in now.
