Radio controlling an arduino aboard an RC aircraft.

How feasible is it to remotely control an arduino using radio at the ranges you'd expect for an RC aircraft? What components would anyone with experience recommend and are there libraries for transmitting basic data easily or would I have to be very involved in getting that to work?

Thanks for any advice you can give :D

Are you planning to control the Arduino with signals sent by the standard aircraft R/C system - for example the Arduino could decode the pulse width from one or two spare channels.

If you want to use a separate wireless system for the Arduino you could probably get an nRF24L01+ system to work.
