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 RCX 10A ESC was only a little warm after a continuous full load after 5-6 minutes.

RCX 10A G Series SimonK (better option)

RCX 10A SS Series SimonK (economy option)

Are Washers 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.
