Someone did that at defcon a few years ago.[1][2] I think it used a surplus army target drone, with an ardupilot flight controller, and either an n900 or openmoko cellphone as the base for the onboard computer and wifi, bluetooth and 3g radios. The general idea was you could connected to the drone via 3g or wifi to control it, and use the other radio to intercept signals. If necessary you could offload heavyweight computation to servers on the ground.
