Arduino, IMU controlling Airplane

Sbright33: As of the KK... googled it, really cool. I also have the same question: Does it also work for airplanes? Do you just plug the 3 servos (2 aileron, 1 elevator), motor(ESC), and a power source into the KK?
Also, how much $ would it be?
It is not a built-in BEC
What do you mean by using an "I2C sensor"? What is it? How would I use it?
