HackRF Controlling a Quadcopter

Over on YouTube user Mike has uploaded a video showing a quadcopter being controlled by the HackRF, a low cost transmit capable software defined radio. Mike uses a Hubson X4 quadcopter and controls it with a USB joystick coupled with GNU Radio. According to a tweet by Micheal Ossmann (the inventor of the HackRF), there were initially USB latency issues that caused problems, but have since been fixed by Mike.
