I run a 1600kv hacker xl motor, similar in power output to a 1515. I am currently geared for mid 40s. My system will get the motor up to about 150f, and will get the fan on the MMM running to. I use flightpower 4500 30c 6s batts and they will get up to 130f. All that tells me is that my setup is working the batts hard. Loots of draw on startup, and lots to put back in under heavy braking. I have a feeling you may stop cooking escs if you step up to a better lipo. Something ;ike a 5000 30c 6s pack. If you still want 50+ mph 6s is the way to go, as it will allow lower gearing than 5s and help with voltage spikes under load.

My buddy runs a savage (not light) with the 2200 combo on 5s and it runs cool and does well, even geared up at 50. We geared it back down as it was a handful.
What the hell took you so long dude?? I always look for your responses! I guess people are right, and I should step the battery up - zippy has a 5000 6S 30C, so I'll get that. However, why is it that battery temps have always been good for me, depsite the low C rating? Is it because I have punch control set way high (or was it low - just so that I can only pull a wheelie from a hard start) and brake power at only like 50%, or is the C rating very conservative on this enerland based pack??

Also, while I like the idea of 6S, as I believe it's better to push the truck with voltage instead of current (which may be completely wrong), is 6S killing ESC's ya think? Is 5S safer for it, despite the rating?
