The cogging is from the sensorless vxl motor. It's just the nature of sensorless setups. The esc can't detect the rotor position upon startup.

Speed passion has some inexpensive sensored setups for $99 on aMain hobbies site when in stock. 17.5t perhaps.

Another option is just getting a sensored motor and wire for the VXL esc you already have. It supports sensored motors with the port on the front of the ESC.

That's good to know. This is the first brushless that I ever owned. I guess that sensorless setups are fine for other types of cars, but why does anyone produce/use them if the sensored motor combos don't have this issue?

Castle has a good explanation:

OK, now I’m confused. Is Sensored better than Sensorless?
The answer is that for most users, Sensorless operation is still better.

Castle’s Sensorless controllers offer best in class start up and braking which are fine for most users. Sensored only motor operation cannot deliver maximum efficiency.

Sensors are terribly inaccurate for motor timing purposes as the motor’s magnetic fields change under load or at speed; that’s where Sensorless operation shines.
Sensorless is also just more dependable. There are fewer wires and connections that need to survive the incredibly rough treatment most RC cars and trucks endure.

Some guys do need sensored operation, mainly because the racing world’s rules require it, but also because it can offer slightly better start up and braking performance. Mamba Max Pro offers the ultimate in flexibility: use it with all your 1/10th motors, sensored or sensorless!
