It's been discussed here previously.

Long story short, it's possible, but expect latency issues with the XBee (comm drop-outs lasting several hundred miliseconds or more, depending on the model and the band it's operating on).

As far as I know there are no regulatory requirements explicitly stating that you should use an RC controller to control your aircraft. It's OK as long as you're in charge, no matter what means you're using (RC, radio modem, leash, whatever).

Thank you for the link. Yeah, I was worried about latency... Are there any other options? WiFi, Bluetooth and the like won't cut it.

I'm not aware of any similar modules with low latency. You could turn off all the error checking and re-transmit functions of the xbee and handle the error detection and correction yourself, that might help in your specific application.

Or you could get a pair of digital radios and do all the networking yourself (something like these), including all the error checking. It might not help at all though. YMMV :)

I found this article regarding latency with Xbee. It might be of some use to someone.
