Some cogging is normal,with sensorless the controller can't sense the rotors position until it's spinning,if it's just on take off then it's ok,it shouldn't do it once the truck is rolling though.It's less noticeable the lower the gearing,if you ran more cells and lowered the gearing to hit the same speeds it's running at now then it will be less noticeable.Goes with the teritory with sensorless,think of it kind of like turbo lag,a PITA but worth it.
