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.

 

Enhancements:

 

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.

Nice... the problem has already been reported on the dev list.
I suggest not flying yet.
Thanks for you test!

Marco

Marco, my APM1 did this on 2.3 as well... just saying, this isn't new to 2.4 or 2.4.1, this issue has been around for some time now...

 Yes, it has been confirmed this existed for quite some time.

Feedback: on my hexa setup, X configuration., MP versoin of 2.4, no GPS fix, rotating nose up, 180degrees, several times like Marco's video and cannot reproduce gray screen. Same result with a 3D Fix.

Actually I did a lot of position hold tuning today (the arducopter is a component of a work experiment :) ) and it flew fine outdoors. Only observation I found is with 4S Lipos, gains are much more sensitive and less forgiving. Today was the 1st time I ran a 3S battery and flight was noticeably better.

Loiter is position hold + ALT hold. I tuned position hold, then alt hold, and then fine tuned loiter.

If you want manual throttle, that's position mode.

If the ALT dips are big (>1m) and it eventually goes unstable (e.g. bigger dip on next dip, such that it will eventually hit the ground), I decreased THR_ALT_I (alt hold) and then THR_RATE_P...

the characters look odd. when I check my DOS screen I see this:

May want to clear your log space (run erase) and log a flight and see if it happens again..

I successfully uploaded 2.4 via the MP to an APM 1.4 1280, thanks guys.

At the risk of nagging: is there any support yet for the X8 frame configuration in this release? Couldn't set it up using the MP Mavlink, can it be done via CLI? Thanks and keep up the good work.

BTW I can use Arduino but not clear as to what to tweak before uploading.
