Product Description

these are genuine T-Motor OEM SHAFT replacement parts SH025 for 2300kv Navigator MN1806 motors  (be careful of fakes from other sources) - Some people ask why they have to replace shafts? the answer is that if you crash doing hard and high risk FPV racing the forces in the crash can bend the shaft internally - the rest of the motor may be fine.  (for FPV ALWAYS wear eye protection!  We NEVER fly without PPE)


  • 2 x MN1806 Motor SHAFT set as per photos

Installing shaft - remove the circlip and release the shaft/bell ; undo the 2 small grub screws locking the shaft ; tap the shaft out ; to assemble reverse the procedure.



  • Excludes tools ; 0.9mm hex tool for grub screw ; circlip pliers ; loctite™
  • Excludes 1806 motor
  • Excludes training - see YouTube

Motor care and set-up 

  • apply 1 small drop of Oil/INOX silicon electrical lube to bearings every 3 hrs with a syringe & dulled-down-needle ; use new clean motor - wipe away excess
  • DO NOT pull on the lead wires - not ever - nothing good comes from breaking wires internally
  • Before pushing the GBC gold connectors into the ESC put one drop of inox Lube in the female ESC connector - INOX is the best for this HERE
  • Do NOT bend lead wires back and forth - risk breaking
  • Use short M2*5mm screws - long screws will go in too far and CUT the windings !!! - risk - cutting insulation
My motor suddenly stutters - was ok before? - Cut throttle - don't fly - Motors won't just stop by magic unless they are damaged/wiring compromised by mis-use
  1. Motors are wound Delta - so each GBC has a pair of 2 inner wires ; most likely one has been broken-pulled-bent internally if the wrong (too long) screws did not cut the windings 
  2. use a DMM  http://www.carbonbird.com/products/uni-t-pen-sized-dmm
  3. check the internal resistance Ω between all 3 input wires - 2 at a time - 3 readings should be identical 0.150Ω - what do you get Ω?
  4. check to see if a lead wire has been broken - pulled - snapped off inside - visually look in
  5. check to see if your lead wires & GBC are compromised - check you have not bent/snapped the ESC outlets off
