Yea, I definitely am thinking I have a motor issue, I have calculated all the roll out ratios and done my homework on what to use, 17 should be fast, I always turn my endpoints down on my m11x, but for this I have everything up to max, even the braking is crap, I have my brakes on the rx8 at 55%, and I always have to turn my endpoints down on my radio, but for this setup I have my endpoint for the brake at 100% and it brakes slow, guess I am going to send this motor back, rx8 is brand new, just frustrated
