WOW! So does it run smooth and quiet besides the minor cogging? I agree that turning it to 'outrunner' will probably treat the cogging issue. I hope you get the programming figured out..
Move throttle to 'min' position...
Turn 'on' esc switch...
Press and hold the esc program button and move the throttle to 'max' and hold..
Release the program button after 2-3 seconds...
Now move the throttle until you hear recognition beep...
You should have entered advanced programming mode... the LED pattern should be the two inside LED's (green and yellow), move the throttle to change, yada yada yada.
