This is the Naked Based version of NK2204 manufactured with Arc N52SH Magnet, Japan EZO Bearing, 0.15mm Nippon Steel Silicon Steel and 7075 High Quality CNC Material.
Many people are looking for light weight motor with better efficiency such as RCX H2205 motor. This NK2204 is the upgraded from H2205 with light weight design plus EZO Bearings, N52SH Magnets, Tight Air Gap and Titanium Alloy Hollow Shaft (easy maintenance).
Important Information on pricing
The key components that would affect the cost a lot are Magnets and Bearings in the motor. The N52SH magnets and EZO bearings are much expensive especially the Japan EZO Bearings. You must compare these two components for the motors you would like to compare (at least same class).
Quality Motor Best for 160-250 frames
NK2204 With Screws
Grub screw to lock the motor shaft from being slipped out to make sure the motor bell will not fly off during flight.
Neat copper wire winding
This NK2204 motor made with Japan Imported Copper Wire, EZO Bearings, 0.15mm Nippon Steel Silicon Steel.
All RCX NK2204 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 NK2204 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 NK-Motors, it is the proof of *balanced*.
Φ16 and Φ19 Mounting Screw Thread
Standard 5mm Prop Shaft with Special Anti-Slip Pattern Circle Plate
This motor designed with standard Φ5mm Prop Mount together with Slip-Resistant Locknut so this can lock up the propeller pretty well. The circle plate has special anti-slip pattern.
Easy To Change The Main Shaft
Unlike traditional style motor. The shaft of NK2204 is very easy to replace when it is damaged during crash. You only need to spend minimum cost for maintenance.
With both 16mm and 19mm mounting options in M3 screw size, it will fit most frames in the market.
Thrust Test Table
Please refer to both Thrust Test Table and the Video Thrust Test (by Third Party) below. You need to monitor the color of copper wire. If the color changes to more deep brown (too hot), that means the combination of battery, propeller and motor does not match, then you need to reduce the battery cell or propeller size.
Where can you get a such high quality motor for such a low price? We are losing money to sell this motor because we want to beat our competitors. We may adjust (raise) the price anytime so you are better to buy as many as you can to save money now.
