Important Notes

  • imperial 0.05" hex tool required - not included
  • Always heat the motor to 120°C to soften up the loctite first - then use an imperial 0.05" hex allen key
  • Make sure the grub screw is no attracted to the inside of the motor bell.

QUESTION - One of my motors stops before the others on shut down? How can i adjust it?

the shaft depth can be set any time in a few secs - this controls the friction setting - by varying the distance slightly between the circlip end and the grub screws (2)

a slight difference in friction has no real effect on flying - but can be set any time if needed
  1. leave the motor connected to the copter - prop and all
  2. - use a 0.05" hex tool - undo the 2 black grubs 1 turn  CCW - 
  3. loosen the axial play of the bell by 1/1000" (freeplay) - pull the bell slightly out toward the prop 
  4. re-tighten the 2 grub screws.
