My Hubsan X4 has a camera, but it doesn't have a way to transmit the video live. Since it also doesn't have the lift to carry the necessary hardware to add a transmitter, I knew I would need to upgrade my drone. After shopping around I settled on the MJX400. This drone had the live wifi transmitter I was looking for, with an android compatible app to view and record the live video, in side by side format, and all for a price I could deal with. $79.99 on Amazon for the DBPOWER MJX X400W FPV Drone with Wifi Camera Live Video
unfortunately, the MJX FPV app does not have a setting to adjust the display, to suit your headset. The result is that the Gear VR lenses zoom in on the image, providing a narrow field of view. I've found I get the best image, using a $15 Cardboard ready headset, from Walmart.
