Cogging does not occur in sensored motors because the sensor always knows what position the magnet is in at all times, which allows for low amounts of current to be applied to the magnet for smoother operation. The opposite can be said for a sensorless motor. The commutator has to locate the center of the magnet and then apply current to the motor depending upon which phase or position the magnet is in at that precise moment in time, the resulting feel is the magnet "jerking" into position as the current is applied to create movement.
The actual jerking you see and hear is the magnet inside the can moving into phase so that the commutator is able to measure back EMF and within a range know what position the magnet is in so as to start applying voltage. A sensored motor always knows what position the magnet is in at all times making initial response and throttle input more responsive resulting in a more linear feel to your sensored set up!

---My question is that is there any company that makes an aluminum front part of the center diff mount. The only complaint i have about this buggy is that everything comes loose so quick on me. And i cant stand the fact that you really cant "Lock" the screws in when they attach to plastic. Any help would be great!! Thanks
I believe KingHeadz and Fioroni both make split center diff mounts for the RC8 line of vehicles. However, if you have not already done so the first thing I would recommend you do is remove that POS stock motor mount that comes with the kit and throw it as far away from you as humanly possible. I hate that thing. Quite frankly it's the only poorly designed part on the car. Get yourself the Elite RC or Grid motor mount and your life will get exponentially easier when it comes to servicing your car at the track. Good luck with it and happy motoring!
