Hi guys,
I have several Craziflie 2.0 and i have a problem with one. The problem is just one motor work, spin, the other three are completely dead. I followed the link https://www.bitcraze.io/getting-started ... yflie-2-0/ to put together all the CFs. This particular CF passed the self-test. I checked the power connectors and they looked. Also I replaced one of the "faulty" motors with a new one but nothing change. Could you please help how to debug this issue?
Many thanks,
Robert

The problem was manufacturing defect, three points without soldering which create a open circuit for the motors.
Thanks

Hi Robert!

Manufacturing defect sounds bad!
Please drop us an email on support@bitcraze.io, we will help you there.
We would also like to understand the reason for this problem and how we can avoid it in the future. Would it be possible for you to include a few photos in the email?

Sorry for the inconvenience!
