MM temps in Traxxas Slash

[Robert]

Batteries are older and have been well loved. I don't mean babied. I mean well used. I did get an occasional cog. I figured that was the batteries having a hiccup. Yes it did seem quicker with the smaller pinion. If the batteries are on their last leg would it run hot with the larger pinion?

It was about 90 here today also. My ESC was much hotter than yours.
