The motor has been balanced by Motion Balancing
Machine so you will see the colored balancing mud in the motor. There are lots of brands who claimed their motors are balanced but in fact it is only static balanced (this means just to filter the highly imbalanced CNC out), its balancing quality is far away from real Dynamic Balancing. If you do not see the balancing mud inside almost all motors, that means their "balanced" word is just a joke. Be Smart & Buy Smart! Dynamic balancing is the most time consuming part when manufacturing a motor so factories don't like to balance the motors due to saving of labor work. RCX always cannot catch up the supply demand due to this reason (production quantity is limited by the balancing work). If a factory can supply heaps of motors to the market, do you think their motors are balanced well? If RCX does not need to balance the motor, the production would be much faster.
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, EZO 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.
With both 12mm mounting in M2 screw size, it will fit most frames in the market.

Bearing and motor shaft are common consumable parts of a motor. You are recommended to replace a new one from time to time after a period of flight time. Replacement of bearings and motor shaft could sometime fix mirror issues. It is better for you to keep some for spare.
