I might be asking to get "flamed" on this one...no pun intended, but I am running 2x 2S LiPos in parallel on my 1/16 Summit. The motor gets hot to the touch, but I haven't hit the ESC thermal cutout yet. I have several questions. First, does the ESC thermal cutout take motor temps into consideration? Second, with my battery setup and stock gears/tires etc, do I need to run with a heat sink on the motor? Third, do the heat sinks with small fans make enough difference to justify the extra few bucks? And finally, will the fan quit working as soon as a little dirt gets into it? I tried a search on these topics but couldn't find anything definitive. Looking forward to your opinions. Thanks!
