Find the Holystone HS200 on Amazon here: http://amzn.to/2gTw0b4. It has altitude hold, wifi FPV, auto-takeoff and auto-land. It comes with everything you need to get in the air.
The only thing you need to provide are the batteries for the controller. I’ve had this quad for a long time and finally got around to doing a video review. This is a really good altitude hold flyer with pretty good pitch and speed. It does have a weird ‘hitch’ when doing high speed turns. Otherwise, its right on par with the gazillion other wifi altitude hold quads out there.
