My DJI Phantom does show air speed, altitude, and pretty much anything else I want to know. My cheaper quads do not show that info... there are laws about flying near airports... typical cheaper quads will fly to a max height of 400-800 feet... my DJI phantom by default has a max celing of 400 feet, but it can be modified... the record holder for height is just shy of 5,000 feet... But I'm going to be honest, that's too high and you aren't going to see it at that height anyways, nor will a standard 2.4ghz remote be able to contact, and once it falls out of range, it either flys home or just shuts off and falls out of the sky until it regains signal.
