This is my first public video with the new Pixhawk board revision 2.4 and for "par condicio" a new one with VR Brain, both install "APM Copter V3.1" code.
After intensive testing the stability of the system is impressive, with this release the APM Copter Developer Team has achieved equal result, if not superior, to the companies that produce closed systems like DJI.
We have so much still to be improved, a small italian team is studying now a new flight mode called "Hybrid Loiter" that allow you to fly more smoothly as "DJI Position Hold", same feeling of flying with "Alt-Hold" mode, just wish we could have something ready i'll post a video with the final result.
I often read of unwanted crash or fly-away, personally with the V3.x code i've hundreds hours of flight without ever having had a single crash, if the hardware is well-balanced/assembled, and the tuning is done as it should be "APM Copter" provides excellent stability and security.
My special thanks to the whole APM Copter Team for having opened the new year with this milestone release, and to 3DRobotics and Virtual Robotix Italia.
Enjoy your flying and fly safe!
Bests, Marco

thanks julien for your work
@Julien: i'm ready, when you have some of "stable", thanks for your work!
@Luc Maximilien: since i'm the lead tester of both the board, the avertising is normal, is not a battle... ;-)
@Crashpilot1000: the "APM Copter V3.1" porting for VR Brain board is here, 1:1 aligned with the related commit, but with a different progressive number (3.1.13):
http://code.google.com/p/vrbrain/source/list?name=Arducopter_3.1-final
Excellent setups, tuning and flying Marco!
@Luc Maximilien I am not sure about pricing but I wouldn't be so convinced of Pixhawk hardware, it may sound pessimistic to you but I wouldn't rule out that VR stuff too soon it may come in handy if price/performance ratio is good and the exact code is available.
BTW: Do you have a link to the exact sourcecode that is running on VR Brain?
That site: http://www.virtualrobotix.com/page/vr-brain-v4-0 is not so keen on linking to the source.
SBUS shouldn't be too hard since many projects have that code:
Autoquad: http://code.google.com/p/autoquad/source/browse/trunk/onboard/futaba.c
Aeroquad: https://github.com/AeroQuad/AeroQuad/blob/master/Libraries/AQ_Recei...
Mwii: http://code.google.com/p/multiwii/source/browse/trunk/MultiWii_shar...
Naze32: https://github.com/multiwii/baseflight/blob/master/src/sbus.c
etc.
Hope to be helpful
Cheers

Since there is now the Pixhawk , I do not really see the interest in another 32 bit board.
Thanks anyway for advertising it.
Some friends have asked me to share the parameters of my little kamikaze multirotor, here the link for download the parameters and the logs about the two flights on the videos in my opening thread.
The log of the flight with Pixhawk contains much more information.
If you double click on the *-fp.kmz" file you can see the two flights in first person with Google Earth.

Hi Cecil ,
on VRBRain 4.x is possible connect the external magnetometer as on APM or Pixhawke .
In last revision of code if you connect the magnetometer on pin 7 and 8 the cpu found it and use the pin 7 and 8 instead as PWM OUT as i2c bus . Then if you use a ppp_sum radio you can continue to fly also with an oktocopter. If you have hexa or quad you fly also with PPM receiver . Now is under developmente the SBUS driver.
Best
Roberto
