Ever since I took my 125B apart and got rid of those thermal pads and used epoxy, the heatsink gets hot quicker and cools quicker indicating better thermal efficiency. Overall temps are less too. So it acts more like the MM heatsink. Since then, I haven't it get anywhere close to too hot to touch.

this is the weird part for me Brian, my esc is not necessarily HOT. I can touch it and keep my hand on it, same with the wires that come out that go to the motor. What happens (i'm sure you heard this already) is that it jsut stops. If I bump the brake then it'll go again for another 3-4 min, then stall, give her a bump, and off I am. And this is on a track jsut doing laps, not really using any brakes either. I called Qaurk, and they said to send it in, but haven't yet. The reason is because I can run for about 15 min before this starts going on.
