I'm new to this ESC....can someone explain a little more in depth about this trick. Is it legit and should I be running it? Thanks in advance.
Yes it is legit. What it is on radios the end point will wander a little and teh esc will not see full speed. What you are doing is setting the end point on the radio down and calibrating the esc and then turning the end point past were it was calibrated so it will for sure see full throttle. If you have a problem with turbo working then not working, this is almost always the solution.
