RS1103 motor is a micro motor designed for micro propeller (eg. 1.7, 1.9, 2 & 3 inches). This motor assembled with high quality Arc N52H Magnet, Genuine NMB Bearing, 0.15mm Nippon Steel Silicon Steel and 7075 High Quality CNC Material. Furthermore, the motor has been balanced by Motion Balancing
Machine so you will see the colored balancing mud in the motor.
Quality Motor Best for 80-110 frames
RS1103 With Micro Grub Screw
It uses a grub screw on locking the motor shaft from being slipped out to make sure the motor bell will not loose during flight. Almost all 11XX micro motors in the market were not installed with a grub screw to lock up the shaft securely which could cause vertical play on the shaft. The top bell was designed ticker in order to install a grub screw to make the motor more secured and durable during crash.
Neat copper wire winding
This RS1103 motor made with Japan Imported Copper Wire, Genuine NMB Bearings, 0.15mm Nippon Steel Silicon Steel.
All RCX RS1103 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 RS1103 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 SE-Motors, it is the proof of *balanced*.
M2 - Φ9 Motor Mounting
Install the T-Propeller using two M2 screws
You can mount the mini propeller directly using two pieces M2 screws easily and securely. The motor also soldered with Soft AWG Cables to make you easier to solder.
With 9mm mounting in M2 screw size, it will fit most micro frames in the market.
Thrust Test Table
Please refer to both Thrust Test Table and the Video Thrust Test (by Third Party) below. You must be careful when the temperature is over 80°C after each flight because the motor might be overused.
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.

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.
