ArduCopter V2 in Action - Full autonomous flight

Here a video of a new serie of tests of my quadcopter (QRO) during a full autonomous flight in RTL and LOITER mode (GPS position Hold)  with the firmware Arducopter v2.0.54 + stability patch. The altitude is only locked by a barometric pressure (no sonar and no optical flow sensor).

The quadcopter autonomous flight is really stable and safe, the Jason' stability patch on the firmware arducopter v2.0.54 is a great improvement.

Wind: W-N-W at 13 km/h

 - triple axis magnetometer HMC5843,
 - 10Hz Mediatek GPS.
 - firmware Arducopter V2.0.54 (original version + stability patch)

 - Receiver: Turnigy 9X8C v2

Great video.

Do you know if the "Jason' stability patch" will be integrated in the next firmware update?

I expect it will be.  Seems pretty solid, the idea, execution and performance of it are pretty good.  And we've got a few more ideas too.

Nice video, arducopter just keeps getting better and better :D, looking forward to testing out the new APMv2 board wich should make for much better alt hold.
