Hello,

I recently built a drone using a kit bought from Arris Hobby, and one of the motors is having issues.  

While looking for the serial number, I noticed that the motor and prop do not appear to match the design of the M10 on the web site.  It's a plastic top and doesn't have the DJI logo or serial number on it.

Is it possible this is counterfeit, or does this match an earlier design?

Hard to say from just a photo

Mabie tinker with it and it might work
