thanks for the reply ive taken it apart, and the slipper pads (or " those white things" as i called them earlier lol )are about 1mm thick, not sure if thats worn or not, i can order new ones so thats no biggie, unless its the diff, then im not sure
ive attached a vid of the motor running freely without spur gear, seems very loud to me, tho its the first brushless motor ive heard in the flesh
also when i run it off the ground and hold one wheel the other spins super fast, (tyre balloning) . Without holding the wheel there is no ballooning at all on either wheel,
when ive seen vids of people running this setup on a stand it seems to go way faster, and sound very different
