Following my recent attempts at maintaining stable flight with my wee remote controlled helicopter, it occurred to me that it would be significantly easier for a computer to fly it than a human A few minutes on Google returned the ChRoMicro - Cheap Robotic Microhelicopter HOWTO. A great site with information on how to have a robotic micro-helicopter for under 500 Euros. I’ve not quite got that cash to spare these days, but I wouldn’t mind giving it a shot when I do :-)
