Above all, HK have a great post quality service with HK post, very fast,
I received the motor within 10 days, more than 2 weeks with swiss post.
anyway, I received the motors, for a mk XL quad, all in good condition, but looking at the motors in details, there is some metal dust, probably machining parts, in each motors.
I tested all motor one by one (got four, waiting for the last one) and no one works like the other, even after a 5mn test, one is really smooth, 2 correct but with some vibration, and the last will not go on my mk, too much vibration. I test and test for CW and CCW for the best results.
Also, Motors have a good ball bearing on the top, but very small one on the bottom.
Ok, it is only 14usd motor but what a pity, it just need a little more attention in control and test.
buy it, only for cheap applications.
