Beautiful work man. Side note- whenever I countersink CF it works fine, is it possible that your countersink bit is dull?

Thanks man... regarding countersinks... I believe the problem I had was that the wrong tools were used to make the countersinks...
A drill bit just doesn't 'cut' it... and I didn't have access to a countersink tool at the time. Recently though, I did find that an abrasive
Dremel tool worked very well... It didn't cut into the carbon, but in stead, it grinds the material away smoothly and reduces the chances of delamination.

You need to make the $7 investment into a countersink bit then

yeah... I guess so

, but I really prefer to stick with the abrasive tool for now.

It continues... I built a little bracket for the heatsink to be bolted to that would fit on the upper plate that didn't appear too intrusive on the design...

... have a look see...

I took the truck to my office parking lot yesterday to put it through passes... I loved the way it performed... it was well balanced and stable despite the surface being wet from a down poor.
I did most of the testing with 16 cells and 14/52 setup... The center diff worked well in keeping the front end on the ground... It just pulled hard through out the rpms until the 14 pinion gave in...
The motor mount screws were loose, so the meshing got messed up. I changed it out for a 16 and tested it on 5s... All I can say is...

WOW!!! The hacker came alive...
Keeping the front wheels on the ground was no longer easy (BTW I am using 50K in the center diff). Needless to say, the front tyres are ballooning like crazy now...

Despite all the fun, I'm still a little concerned about the temps... the motor went to the high 160s and esc was floating around 135/140... I might be going back to the 14 pinion
(need to order new ones) to lower the temps on the esc and add a little fan on the motor to try and keep it cooler.

More to come... I hope.
