two fast questions!!!

Once you get into the castle link programming, I'd update it, then set your start power to high and disable punch control and of course set your lipo cutoff. Thats about the only thing I can think of to help keep your esc temps down some. Perhaps getting some airflow to it will help with body mod?

Both my PC and Laptop gave me that warning message. Neither one of them have crashed since loading and using Castle Link. Typical MS BS. Anyway, not familiar with the the mega motors. I've got an E-Max running a MM and Neu 1512 1Y (2750KV). I'm using a CC BEC and a glitch buster cap on my Rx. I put two fans on the MM, one blows on the heatsink, the other in through a 3/4" hole in the back of the case. Small holes all around the sides of the case to let air back out. Temps stay under 150 as long as both fans are working. Lost the one on the sink in a main and temps went to 180 pretty quick. Running 2@ 2S 8K LiPo. Punch control at 70%, brake at 40%, start on high, timing lowest. The MM is not really meant for Montser Truck duty. It's a temporary while my MMMs get put back together. If you get the BEC, that will help some with the temps, and 4S gives you more voltage, less amps, so that takes some of the heat off the ESC to. Your going to be working a 3S 5K 20C pack awfull hard in an E-Revo. The 2s 8k MaxAmps were at 105 degF and only took 3200mah to recharge after a 10 minute main. Not sure about the differences between motors, but the weight of the trucks should be similar so I hope some of this helps.
