Dear friend,
This is last video doing by Marco with his Marcopter HV2 Full Carbon
yesterday we release last revision of Arducopter rev3.1rc5 for VRBrain with no OS the AP_HAL_VRBrain is very similar to APM.
more tech info about vrbrain here : http://www.virtualrobotix.com/page/vr-brain-v4-0
The name of our revision is APM Copter rev 3.1.11 this release is without OS , We have also available the NuttX-PX4 revision of code but only in alpha revision for dev team test.
see here for more detail on nuttx os on VRBrain : http://www.virtualrobotix.com/profiles/blogs/vrbrain-4-5-last-updat...
On VRBrain the Arducopter code use use only 6-7 % of cpu resource .... on APM 2.x use from 70 % to 95 % of cpu ... so we have a lot of resource available for doing reliable test of advanced functionality . The code need only 480 kbyte we have available 60 % of flash for develop new functionality .
Last revision of code work very well ... we are very happy of these fly result ... in italy a big community of user start to switch to VRBrain from Arduflyer or Cirus Board AIO.

Update in 3.1.11
- SPI BUS speed for MPU6000 increased to 8MHz
- ENHANCEMENT of MPU6000 enabled by default (MPU6000 @ 1KHz and gyro full scale @ 1000dps)
- update to latest 3.1rc5 of arducopter code
- Corrected bug in Dataflash log download
- Yellow led on board now show Scheduler activity.
THe Gyro and Accels now are sampled at 1KHz instead of 200Hz and main loop averages 10 samples every main loop.
This has imprved flight performance, but it is still in test, so use accordingly. With this version you can try to rise the INS_FILTER partameter to 42Hz or 98Hz, but you must have vibration under control.
Have fun and fly safe!
Best
Roberto

Really nice! ;-)
Thanks for the info guys. Looks like the VRBrain and Pixhawk are about the same price and similar in capabilities. Are there any major differences between the two?
Hi Bill,
yes Marco disable on board compass for use external compass , on VRBrain there are a lot of option for add an external compass ... 1 hardware as apm 2.5 cut the sda wire on onboard magnetometer the other software .... use external spi magnetometer connected to spi expansion bus the other is to use the i2c magnetometer on second i2c available on pin 7 and 8 if you use quad or hexa configuration .
The spi magnetometer is experimental but the new HMC5983 have better resolution respect of HMC5883
Yes, the compass is selected via a user settable parameter. For multicopters, the best choice is to use the external compass in the GPS.
Nice flying Marco!
Nice!
Looks like it has an on-board compass. Is this disabled for use with the 3DR uBlox GPS with Comapass kit?
