For the price the quadcopter in the above video would be a great option to keep the kids away from your Mavic. Could also be used as a trainer drone to fly with before investing into a professional setup like the Mavic Pro.
The video pretty much speaks for itself, so I don't need to post a bunch of info about it here. I stumbled across the video and thought I would share it for those that might be looking for something like this now.
Enjoy....
