Open-Box ReviewFinally, I got my new Team Trinity Kill Shot RPM 13.5T Motor yesterday.
Motor Shimming TipsOverall, The rotor spin very smoothly, but I feel that the rotor has no tiny bit slop movement, which means it has been shimmed very firmly. I have to re-shimmed it for better performance.
Be caution with handling those shims, if you accidentally drop them on floor, they may bounce to no where that you can never get them back.
Please note: motor shimming may vary because of manufacture deviation. In my case, I have put three 0.3mm and one 0.1mm shims on the back.
Why we have to do this? Because your motor can gain a little bit more torque with correct spacing between rotor and sensor unit. leave a little free play can also help motor produce less heat.
