I've recently purchased a used Karma off eBay, that didn't come with a camera. Since I'm still in the process of bidding on some Hero 5 blacks (the GoPros I currently have are Hero 2s!), I was curious and can't seem to find it anywhere - can I do the in-controller simulation and learn how to fly while waiting on a camera? Or do I have to have a camera installed in the drone to even do that?
