Neweuser: Well, you can donate it me if you'd like. :) If you do what I did, you will only need one 3mm thick slab. Regular AS adhesive has some capacitive properties and might cause problems if it drips onto the legs of the FETs (especially the gate lead). AS has another type that is non-conductive and non-capacitive. However, I was careful and used the normal stuff and haven't had any problems. I'm sure the use of the padding was somewhat determined by ease of working on it. I know mine is useless for warranty work now, but I personally think it was worth it for the thermal performance compared to what it was before the mod.

zeropointbug: From what I can tell, the slab is more of a spacer. The electrolytic caps on the end of the ESC are a little higher than the tops of the FETs, so the slab takes up some of that space. It probably also acts like a heatspreader to some degree as well.

The datasheet for the FETs can be found here. In this post, I made some observations about these FETs and why they may not like 6s. make sure to look at the derating charts...
