But anyhow, lincpimp. nice info. Part of the reason why the 7xl is overheating more than the 14xl could be that your 4s pack holds its voltage better at twice the current than than your 8s pack, which would also explain additional esc heat too. A fairer test would be to put two 4s 3600 12c packs in parallel and run them with the 7xl. If you want to compare escs the higher voltage one has to be the same brand with half the amp rating. Then again, you also have to adjust the wire guage appropriately.
Also I have owned five differnt feigao motors: 540 6s, 380c 9t, 380 12s, 540 8xl, 540 9l, and my findings have been random. The 380c 9t always ran coolest on 6-7 cells ni-mh, and ran hotter on 3s lipo, but still within an acceptable level, while the 380 12s ran coolest on 3s (still hotter than the 9t on 3s) and could even not be run on 6 or 7 cells nimh without seriously burning my finger. Weird huh and ive tested different gear ratios with the same results. So it's my speculation that the voltage and current needed to keep the motor cool vary from motor to motor, or that it's the luck of the draw whether you will get a good feigao motor. My 540 9l in my 8ight btw cannot be run on 3s no matter what gearing and overheats the MM too, but it can run for a longer period of time on 4s. Other people that I have heard from claim that the 9l runs just fine on 3s.
Again, I've never denied that higher voltage is better, but where comes the point were a 6s setup can't be used? If that point is beyond what 95% of the people are looking for, then I find it a little rude to beg Castle to begin making 12s system while they are still working their a** off to get their 6s system that many people have been waiting for ages, out to the shelves, thats all.

It's not that we are begging. Patrick said he would do 2 versions a few months back. Plus Castle needs to fill that gap to add a HV car controller so we (The ones who likes HV) can have a US company with one.
