I ran 5s on my Quark for the most part and it did fine. The only glitch I had was going for about 15min, then if I let off the throttle, it would not go again until I bumped the brake. This tells me that it's not a thermal issue, the Quark was not even hot (98*), so not sure. Have not tested the 4s in the heat yet, so we will see what happens with that. Other than that, I never had issues with the esc saving the settings. I have been told that if you use the lowest setting on all the settings, you will have better luck with the issues of heat and performance.
