IMU with Kalman filter

I found I am too lazy and almost over a year I didn't have any big junp on UAV development. even the bi-pedal robot as well. recently I found a WEB from belgium, This guy most probably is a student who have the same target as me and he also delay more than 2 years. But finally he work out the very pretty good UAV. I think I need to hurry up. here below is his WEB

As I mentioned before, Kalman filter is a necessary method for Aerial vehicle to minimize the un-necessary noise which induced by the shaking, vibration from engine or wind blow instantly. here show the captioned guy demonstrate the IMU with and wihtout Kalman filter.
