I'm surprised you're having trouble with heat, but a 130 degree LiPo is HOT, as in ready to burst into flame. I run a MM 5700 in my T4 stadium truck with 3S A123. I get 13+ mins runtime, motor temp = 130ish, ESC = 115ish, Batts = warm. Have you checked driveline for binding, too tight gear mesh, etc? I think something else is at work here.

I think a lot of it has to do with my bashing style (I don't live anywhere near a track right now) which is a lot of WOT acceleration and running with some hard braking in large parking lots and grass fields. The drive train is very smooth, the gear mesh is nice with just a littlespace in the gears for chassis flex, and I blow all the in's and out's till they're spotless with an air compressor after every run. (Translation - I am a anal obsessive compulsive clean freak
)
I know that the MM won't support 6S so that means either moving to a Quark or a MMM hen available. There is also a substantial capital investment involved in moving to 6S as my balancers only work to 5S and I will have to get 6S packs (which are to $$$ in the 2200mAh-2600mAh range) and may break down and get a TP 1010C charger with 210V balancer (been checking them out and like how they can work together). I've been using a TP 205V balancer up till now and all my packs have TP balancing connectors.
This is why I'd like to hear from some more people that the investment will pay off to some extent (other than that it becomes an expensive experiment, but I'm dying to try something new with spring here not having spent much $$$ on RC over the winter). Plus I expect the 6S investment to pay off when the e-revo is available as I hope to get one towards the end of the year.
