Tips1:The numbers of different models represent different sizes of motors;
for example, 412 is 4mm * 12mm, 8520 is 8.5mm * 20mm
Type A is a red and blue line, and type B is a black and white line.
All motors can be CW or CCW.

There are propellers in our shop, and there are more discounts when buying motors and propellers together.
