I have the same exact problem right of the box. Just got as a gift this Xmas. Sad that it was defective right of the box. Warranty hopefully will replace the model.
Drone has been flying well for the past 6 months, I guess it was nothing ? Thanks to everyone that has responded anyway.. Please check out my tricopter videos. It makes my drone look like a childs toy ;)
cool thanks for the feedback. I havent flown for weeks since I have been building a tricopter (see my other videos) but a couple of days ago it was bobbing up and down a bit, maybe needs lubrication or could be a sign that bearings are wearing ?
The effect is called 'cogging torque'. It’s mainly caused by an interaction of the permanent magnets and the iron stator. The level of cogging torque and the number of cycles per turn is influenced by numerous factors, such as the number of magnets and stator teeth (they hold the coils) and, most importantly, tolerances…

…I assume that the device uses four ‘cheap’ brushless motors, where manufacturing tolerances are secondary. Cogging torque is undesired for several reasons, but in your case it will not influence the performance to a noticeable degree. The level of noise and vibration might differ between the motors however.
Are they magnet motors ? it could be the magnets snapping into place like alot of magnet motors do. Thats just my thought hope it helps and i hope you get it sorted if there is a problem

@jbalatutube
I have the same with my Drone but then with the right front engine, but i'm flying with it for over a year now without any troubles!

p.s Perhaps the one that is smooth is the one with a problem ^^

you dont have a problem with any of your motors, mine does the same thing and it flies perfectly.....

@bongbeltran - Thanks for that, I got my new motherboard from HK support and it is flying like new.. Hopefully that motor holds together !!

Looks like a dodgy motor to me! Well that's my 2 cents worth
