There is Ryzen Tello, which can be controlled by gamepad + smartphone, but on their FAQ page they said that they support only Gamestir controllers and video quality is not very good (though I've seen videos where people was able to control it with some latency using other controllers).
Can't say about preferable price range, but affordability is appreciated.
And quality of video: my smartphone has more pixels than one good model of photocamera, though camera of course has better quality of images. But I would say starting from 720p would be ok, if video-quality is not smartphone-like. Or may be I could attach lighweight camera to the cameraless drone.
For people who already have a gamepad compatable with Android (MADCATZ CTRL Z for instance)?
