The most stable and maneuverable Quadcopter

It's perfectly stabilized,
fast, very maneuverable and easy controllable. Enjoy flying!
A, D and vertical slider - control, F - on/off, G -automatic brakes, horizontal slider - angle and acceleration control.
PC controls:
A, D, F and G - the same, W and S - fly up and down, Space - set speed of movement up and down, (controls vertical slider)
There is a limiter in acceleration control, so if you need more acceleration just hold horizontal slider or E.
Numfeed shows speed of movement along X-axis.

Maybe it's will be the best flying thing you've ever seen. Seriously, it PERFECT *-*

UPD1: added automatic brakes, numfeed

UPD2: increased maneuverability, discreased angle while low speed, improved auto-breaks

UPD3: angle and acceleration control

UPD4: horizontal slider also controls max.speed, quadcopter's angle returns while flying

Well... Yeah, it wasn't copleted. I hope NOW it's really completed
UPD5: progam tiltmeter and gyroscope, physical ones are deleted; now you're able to land without deactivating (F)

UPD6: improved controls from PC
