It's destiny is to rip HARD!
Those DYS Samguk motors are very nice on Fushi bearing. Low budget best choice.

Maybe will instal a GPS to measure speed :)

It's commonly known that these motors came out from factory with cheap crappy bearring.
Now they are great :)

Now we've got the best of both worlds and what..
