Best torque and performance within reasonable and safe temp. If you gear a lower kv motor to have the same top speed as a higher kv motor it will obviously run hotter but several times now I've read "the 1700kv runs hotter". It doesn't, it's just being run in an over-geared condition to attempt to get the same top-speed as a 1900-2000kv motor when it's not supposed to be as fast.

Accept a couple less mph. less top speed and enjoy the extra run time and controllable torque.

It will be interesting to see what the sweet spot power system will be with this new chassis. It'll be light enough to possibly open up some other, more mild options while yielding good performance. Anything we can do to strain the electronics less is a good thing for E-1/8.
