We test HV 4S batteries and a stronger servo in the Traxxas X-Maxx 8S. Standard versus high voltage lipos, Traxxas radio binding and a test drive. Let's go!
(I was supplied the batteries for review. I bought the X-Maxx, the servo and all other mods listed below)

A Note on Sponsored Content:
While I am technically an 'influencer', I treat my role here as more like a journalist. Integrity is a core value of mine and I promise I will always present as honest and transparent a review as possible. I am prepared to burn bridges with a manufacturer or store before I compromise on this. Just wanted you to know.
