There are already 802.11 drones with video and cell phones that can act as a wireless hot spot. Combine the two and I don't think latency would be bad enough to prevent you from flying it remotely.

I would be more concerned with battery life or dangers of mechanical failure on something large enough to use liquid fuel.
