[Old Driver]

This is a dji phantom 4. The camera comes with, they older versions used a go pro option. I bought it for the wife who loves taking picturesbut somehow I ended up (stuck) with it. Very easy to fly so far. Once it's 400 feet in the air you pretty much can't even hear it. The video does 4k but my computer can't even play that quality.
