[Olivier] told us about this great job where he developed his own RC airplane. The airplane itself is nothing special, it is the controls that are worth paying interest to. He utilized an Arduino Diecemilla , some XBee transceivers, as well as a SparkFun Wee. The primary site is a general overview, however there are links to a lot more in-depth breakdowns of exactly how to develop a few of the parts. There are a number of videos of him flying it as well.
