NO drone can fly up to 3500. There are no hobby radios with that control or fpv range. PERIOD. Do your research before disparaging people. Amazon and others are fighting for our hobby airspace and the hobby is under duress. Please don't fall for this hype and defend what's been a mainstay of flying for over a century for heaven's sake!
This is baloney. There are no consumer options for this altitude. If it was up there, it was DOD or other classified event. You're disparaging an age old hobby that is passed down from generation to generation and from which, many serious and talented pilots come from.
