LOSI LST XXL Conversion ideas

[mistercrash]

I updated my MMM with new settings, it was at 10° timing so I went to 0° and brought down the braking from 40% to 30%. The motor temp went down a bit from 200 to 190. ESC was at 135 and lipos at 118. It's a little better but not quite enough. The weather was pretty much the same as the other day, very hot and humid and I was running the same lipos, bashing in the same spot and doing the same things with the truck which is run it fast and jump it high. I'm thinking a motor heat sink would help.

Anyone know where I can find a good heat sink for a 40 mm motor?

How in the world did a rock get in there, and when I yanked it out, I noticed my first breakage of a suspension component.
