I ran the ESC in the tray on a low bite track this past weekend and it was ok. I went faster than the week before but I think that was more because of better tire choice. I'll be on a medium bite track this weekend that I'm more familiar with. I should be able to see how it effected it more after that. As long as it doesn't make it worse, I'm keeping it. I cut a ton of weight due to less wiring, and it looks cooler, which as everyone knows, is the most important part of racing
