Quality Motor Best for 130-160 frames



NK1407 With Grub Screw
It uses grub screw on locking the motor shaft from being slipped out to make sure the motor bell will not fly off during flight.



Neat copper wire winding 
This NK1407 motor made with Japan Imported Copper Wire, NSK Bearings, 0.15mm Nippon Steel Silicon Steel.



All RCX NK1407 Motors Are Factory Balanced!!
Unlike most other brands who do not balance their motors (or just lie that the motor has been balanced). All of our NK1407 motors have been balanced by Dynamic Balancing Machine. It takes time so the production quantity (bottleneck) is limited. You will see the balancing mud in most of RCX RS-Motors, it is the proof of *balanced*.



Standard Φ12 in M2 Mounting Screw Thread



Standard 5mm Prop Shaft with Anti-Slip Aluminium Locknut
This motor designed with standard Φ5mm Prop Mount together with Slip-Resistant Locknut so this can lock up the propeller pretty well.



AWG Soft Cable for Easy Soldering
This motor was soldered with long soft #24 AWG cables for easy soldering and wiring. Shorten these cables if you do not need them that long, it will help on losing weight.
