Inside the Quark 125, pics.

Here is what the insides look like.The plastic end of the ESC keeps popping open (battery wire side). So I opened it all the way. I was thermaling today even with heatsinks and fans. I think the plastic end holds it so the fets are pushing on the thermal pad. I'm thinking just bond a heatsink directly to the fets. Then shrink wrap it, but I'm a novice when it comes to electronics. Anyone have any ideas for keeping it even cooler.
