As Taobao some of the restrictions on second-hand goods, this product is actually used disassemble, second-hand disassemble, second-hand disassemble.

1: disassemble the goods, cut the line Qigen, Fun need hands-on ability, will be welding players. Weight 38g, gear box are plastic, work well, without any oil, the buyer opened the white grease on the lip, it is estimated that the resistance and noise will be better. Although there is no packaging, but because it is brushless, gear plastic self-lubricating, as well as the use of value, do electric (brushless controller or brushless ESC, can not be directly inserted), can also be used to generate electricity, hand Shaft can send about 5V three-phase AC (available three-phase rectifier bridge or a number of diodes or two single-phase rectifier into DC, the higher the voltage the higher the speed).

2: 2-stage planetary deceleration, the first stage reduction ratio 39: 6, the second stage 39: 9, the total speed ratio of about 28.2: 1, planetary deceleration output power, gear long life (3 or 4 teeth at the same time, Ordinary deceleration single tooth force)

3: With 3 switch Hall, but such a small brushless generally do not needHall. With no sense of driving only then the ABC coil,Hall circuit is not connected.

4: low clearance
