sounds great! hopefully someone will translate your tutorial.
i'm wondering if an arduino quadcopter was possible (see mikrokopter.de (german project page), they're using an ATMEGA644 for their flightctrl-board).
did you look into this option or do you want to stick to your helicopter?i asked a friend who's currently visiting korea to see if he can get me some brushless dc-motors plus controllers as these are quite expensive here... hopefully he did not not forget about me
we should have a forum fork for aerial research and get arduino into the air! navigating autonomously :
great work!

Ohh yes, i readed it like 3 times jeje, actually the technology they use are infrared sensor like this: http://paparazzi.enac.fr/wiki/index.php/Sensors
, they use the IR to generate a virtual horizon to stabilize the helicopter, is better than accelerometer (alone), because the rotor vibrations make interference and the heli lose control.
Another option to create a virtual horizon is to use a combination of gyro's and accelerometer with kalman filters like this: MAV-blog : Kalman demo application
I able to do the same with arduino but... right now i dont have MONEY.. maybe santaclus bring me something :-[. But someday when is done, for sure ill post it... :
