Announcing: ArduCopter 2.7

In just a short while, ArduCopter 2.7 will become available for download in Mission Planner. As we worked on ArduCopter 2.6.1, we saw that it had several new and compelling features (as well as many bug fixes and improvement) so it was decided to make this a major version release. 

A full list of changes is here, but they include:

 

New and Improved:

  • NEW: 3-axis camera stabilization
  • NEW: AP_Limits library: Altitude limits and geofencing.
  • NEW: Automatic Flip (Roll axis) is now enabled on Channel 
  • NEW: GPS lag estimator
  • Better altitude control in ALT_HOLD and better altitude transitions
  • Better loiter, especially with the new 3DR uBlox GPS. Check out the video from Marco above!
  • Better yaw control
  • Better DCM implementation, resulting in noticeably smoother flight
  • Better velocity control in Auto missions
  • Etc

Bugfixes:

  • Fix to dataflash erasing, which should resolve an issue some users were having
  • Fix some MAVLink commands
  • Fix Circle command
  • Fix some units
  • Etc

Notes:

No more 1280 support (out of program space)

Yeah John write that blog. I've come accross this very question at least 3 times in the last few days. Lots of people want to do it. I think Tridge made a post a while back - but that might be out of date now.

Just gets better and better! Congrats go the development team!

Fred_fr, I've asked question about "toy" mode in two places, no answer yet. Sounds like a mystery we should solve by our own ;-)

Toy mode is still under development I believe.

Working well down under. Using a 50cm X quad frame, 924kv motors, 10inch props.

It seems smoother all round including descending.

Using apm2 and optical flow sensor. Xbee900 for telemetry. 

Well done guys !!

Yes, Toy is still under development. It's flyable but I just realized it has a sign error that really limits performance. The idea is it's a simplified mode that flies from only the right stick. Yaw and roll are coupled. 

Fix is this:

roll_rate = -(g.rc_2.control_in * (yaw_rate/100)) / 40;

3-axis stabilization.. interesting. Any video results with this implemented?

Can anyone point to where in the code this camera mount stabilization is located?  My brief search of the changes didn't find anything significant.

Pitch and roll camera stabilization stops working upon loading 2.7 firmware :(  Its probably just one of the new settings I have been overlooking?

I just switched from 2.6 to 2.7 on my dev quadcopter.  The copter is a custom built frame with 3530 1100kv motors and APM2.  First impression is that attitude is very good with stock PID's. 

Loiter is holding within 3 feet with stock settings in my backyard....and that is with 15mph wind (18mph gusts) today! 

Altitude hold is not holding as well.  It's probably just that I need to adjust my settings a bit. 


Camera stabilization on pitch and roll is completely inactive.  I checked in the settings and it looks to be set correctly.

Good job guys. Problem is I flashed to Arduplane (to run an experiment I got here) and it will not connect to MP 1.99, no heartbeats being sent from the APM. CLI on Arduplane works fine though.

Reflash to a quad and works fine so far. (but need Arduplane working...)

No more 1280 support  :(

I guess it's time to start developing on the VBrain board I have here...
