Version 2.4 of the ArduCopter code is now available in the AP Mission Planner and in the downloads area.  Although not as big a change as the 2.3 release, it still includes a respectable number of enhancements and bug fixes.




Bug fixes:


The default PIDs are optimized for a 3DR/Jdrones quad with 850 motors and 10" props. If you're using more powerful motors/props, start by turning down Rate Roll P in 25% steps.


Thanks go to the numerous contributors including users and their detailed bug reports, developers and testers.  Hopefully all together this will add up to a nice smooth release!


As per usual, please post your comments, issues in this discussion.  For enhancement requests for future versions, feel free to add them to the issues list.  Note:  you can "star" an issue to receive emails when someone comments on the item.  On the dev side it helps us because we can get an idea as to which feature requests are the most popular by sorting by the number of people how have starred each issue.

Just uncomment the // # define CONFIG_APM_HARDWARE_APM2

Everything else you can do in mission planner if you have a fairly stock set up.

Thanks dave. wish me luck.

Bon voyage :)

Just flew the latest GIT and can confirm it flies smooth.

First flight I noticed that yaw was going from left to right about 15°. I then recalibrated the compass through the MP and it worked great. I'm using the sparkfun magn.

ALthold reacts slow. Wlst te other mention quick reactions?

Hopefully tomorrow some more tests.

Using X650 value frame with apm1, MT2812 710Kv motors with 11x4.7 APC SF and 3000 up to 5000 mAh batts.

How does the compass calibration work? I just got my APM2 yesterday and I noticed this feature on the latest MP...tried it and after it's done it says to write down some offsets for manual entery...where do these go?

Robert, "by no real problem" what you mean actually ? Did the heli hover handsfree for long ?

Which heli it was ?

An Align 600 clone.  I didn't do much loiter because I haven't figured out how to tune it yet, and my sonar is broken.  It didn't do anything stupid though.  

The heli does pretty much hover hands-off in stabilize mode if you don't mind the wind blowing it around.

By real problems, I mean, things in the code.  My not real problems are, sonar signal is garbage, and I had some kind of glitch in my ESC or something I'm not sure yet.

I used MP 1.1.52 and calibration was automatic after I turn the quad for 30sec in the different axes.

It seemed to work though.

Yup, I used that too with 1.1.51.  I like the feature.  It's optional, but I like knowing that I have a successful calibration before I fly.

double post
