The other day I sent my Phantom 3 Pro in to get fixed. I got a quote back totaling over $900. I am just a teenager so i don't have that kind of money. My dad is very experienced with drone repair and i just want to buy the singular part(The drone had some minor scratches and broken plastic). Does anybody know where i can get parts? The part I need is atached via photos.

There are loads of outlets on Ebay here in the UK, I'm sure you'll find something there.
What specifically were you after?
You can get a good second hand complete P3P for way less than that sort of money!! Again, get on Ebay

Yeah I bought a refurbished P3P quite a few years ago for $550 something.  Warranty and everything!  $900 for a repair seems a bit high.  Look at eBay for used parts.  Good luck.

@Mark The Droner  @chedder-man I still don't want to spend that much money. I am looking for quote on quote, "Phantom 3 Professional Gimbal Yaw-axis Video Downlink Main Board". I can't find this.
