Rebuild 450TH



The magnets are prone to loosen on crash. Without taking out the bell, you can still CA the magnet back in place but is quite difficult.

Open up the bell:




  • place a 1mm thick metal between the bell and the stator base.


  • Use a 2.5- 3mm pin to hammer out the bell pin from the end of the bell. This requir a heavy hammer.


  • The bell side bearing will usually be damaged.



Take out the stator fromt the stator base:




  • Use a pin to struck the stator slightly out from the base. This will have enough space to put in a bearing clamp and the whole stator is pulled out.
    use 0.25mm x 10wires x 4.5 wind per stator teeth.

Use a spacer (3mm x 5mm spacer from carbon blade) to support the pinion. Ne need to loctite the bearing for easy renewal of bearing later.
