Team Xray XB4 | learning to change diff oil

I recently bought a Xray XB4 & XB2 19 secondhand and am loving the cars. As I begin racing with them I’m also learning how they go together and how best to maintain them — can’t have a badly prepped car as the excuse for poor race results! We’ll have to put that on the driver ;) Hopefully other learner RC car drivers can pick up some confidence, help and if you have more experience please do lend your advice in the comments. Thanks for watching and please like & subscribe as it really helps build the RC community 👍
