One last thing. I had the RS on the car.. when I used throttle it seemed whiny.. I did not like the sound out of the geartrain.. did not seem like mechanical to me.

Swapped a Trackstar 120amp genII esc in.. and I am much happier, the fan still dips a bit, but not as bad, and the "noise" or whine is gone.. sounds normal.

The Tekin RS seems to be working right.. but maybe its not? I have contacted Tekin, no idea what "repair" is worth.
