"I spoke with Christian earlier today because I thought that my recently ordered and received eRC 45A ESC was defective. Christian told me to see the trouble shooting video on your website which made all the difference. My ESC now works fine thanks to that video. I would like to make a suggestion that you refer and even emphasize to all customers in your literature/instruction sheet that comes with the product to consult the video or indicate somewhere in the instructions that throttle settings on different transmitters may have to be adjusted to calibrate the ESC properly. For your reference, my transmitter is a Hitec Aurora 9 which required that I bring the throttle trim to its lowest setting for the ESC to calibrate. Other than that, I am now very satisfied thanks to Christian's assistance and Jason's video."
