Hi guys! I've Got an MJX bugs3. IT flew nicely at first but now it got a bit wobbly or or how to say it... When i try to just hover with it, it's going up and down and if I can make it stay in one place it kinda Shakes. I found a video with similar problem:
Some people said they swapped the main board or or so called receiver but it stood the same. Could you guys give me advices?

Sorry for my broken english, and If it's a bad question :)
 
It's Done. On the quad and the transmitter too. It's kinda horizontal shake. Like one of the motors works too much or not enough and IT jumps a bit. And it's much harder to control.

On the video it's near 12 secs when wou see It.

It became realy hard to hoover, and IT changes the direction of the front ( so yaws )

Take the prop off and inspect the motor. Sometimes even a piece of thread or other debris wrapped around the shaft can cause this issue
 
I wouldn't, a visual inspection should be enough. Does this motor spin by hand as freely as the others?
 
It's brushless (if that matters) all of motors can can be spinned by hand with the Same easiness I think. And i dont know which motor malfunctions...
 
It might be propwash. It looks good. Could probably use some PID tuning, but from the video it doesn't look bad. Have any first person video or blackbox data?
