Which ESC is suitable for this motor?
The testing (with 3S Li-Po, 10A ESC and both 5030 2-Blade & 3-Blade Propeller) shows that this motor demands between 7.5 - 8.5A during full load (100% Throttle). So a 10A ESC is preferred to avoid overheat if you plan to drive this motor hard. The temperature of ZMR 10A ESC was only a little warm after a continuous full load after 5-6 minutes.
ZMR 10A G Series SimonK (better option)
ZMR 10A SS Series SimonK (economy option)
A wholesales customer reported that the motors work beautifully which he used 4S 2200mAh 25C with 12A ESC on 5030 Props. But we have not yet tried so it is not guaranteed but you are welcome to report.

Why this motor has *R and without *R?
When you run your Quadcopter, you need Two Clockwise and Two Anti-Clockwise motors. So the design of this motor is that the Clockwise motor is spinning with counter-clockwise thread to avoid the Nut (the top bullet head) loosing off from the motor. So in most case, you should purchase one with *R and another one without *R to make up one pair.

Bearing, Circlip, Prop Mount Nut (Bullet Head) and Motor Case (with Shaft Installed) can be purchased separately. If the motor is not running smoothly, it is properly due bad bearing or bad motor shaft so you can just replace the bearing or the motor case. Bearings and Motor Shaft are common replacement parts for motor so you need them from time to time (please keep some for spare). You will also lose the Circlip easily when you repair the motor.

Washer Needed?
Depends on the thickness of the frame which you will install this motor, you might need to use a washer with the screws because they might be too long if your frame is thin. So you need to check this carefully during the installation (to see whether the screw is too close to the motor wire inside. If yes, then you need to use a washer).

The Washer needed is M2 Washer. Beside using washers, you may also consider to use shorter screws eg. 2*5 or 2*4 depends on the thickness of the frame.

The thickness of the frame that this motor was originally designed for is 2.2mm. The screw is about 2*6 (Diameter is about 2mm and the total length is about 5.8mm). So in that case if the thickness of your frame is less than 2.2mm, then you might need to use a Washer, and you need to check carefully during installation whether the screw is too long which touches of the wire inside the motor.
