Chosen Solution
I crashed with my brothers drone and after one of my motors was not working as we’ll as the others so it would not take off. I checked the battery and it was fully charged but the motor would be slow to spin when started. My brothers drone sustained no damage . How can I fix it and how much would it cost to get someone else to.
You can get a new motor with this kit. However, it requires basic soldering. I have the X11 with same symptoms. A new motor should fix it.
The link given by @pccheese is broken. Try AliExpress. Make sure you get motors of exactly the same length and diameter.
