The major upgrade in this drone, is telemetry, and in flight mission augmentation. We could set it to return to take off location, auto land, linger, or go to specific way points. It used APM as the flight controller, and had nearly 17Amp hours of battery allowing it to stay out for about an hour. For a 6 ft plane, that's pretty impressive.
I do have some technical specs though, which I pulled out of my email.
