Is it possible to control/fly a Phantom using a transmitter attached to a PC? I'd also like to know if anyone has figured out how to program the NAZA to fly and land at a specific GPS location. Basically, how to hardcode the "home" location so it uses auto-pilot to fly to a different location than where the Phantom was powered on? I'm having fun with my new Phantom and looking to add non-conventional upgrades such as "grippers" to carry a ball. Thanks.
