why is my quark getting so hot?

I agree; no need to do the mod if you don't have to. I'm kinda rough on my trucks (unintentional crashing mostly) so the ESC gets jarred a lot, so that's why I mod mine pretty much right away. Just keep in mind that if you start getting thermals all of a sudden, it might be because the thermal tape has let go and the ESC internals have seperated from the heatsink, at which point you have two choices: 1) send it back to Quark for repair, or 2) do the mod and not worry about it anymore.
