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.

APM 2 correct? 

Looking forward to flying this!

I am using an APM 2 but it will work on the APM 1 too...

Thanks JL for your first "cavia" test... :P
Excellent results, but it is too early to declare victory.

Your flights are always so rock solid JL that I dont know what to think... you are a master at PID config! 

This is a really good news and we need to test the heck out of it to be sure there is no other introduced bugs... do you have a video to go with this wonderful graph? 

Of, course, Marco, I agree with you, we need to push the flight enveloppe, but after this 1st test flight, I am very confident about the soon results. Now, I have the feeling that this (very) old problem is cleared...


Sounds good dear JL... tomorrow my tests/video with the latest Tridge patch! :P

Brilliant! Well done every body!

Standing by... :)

In other news I got 2.4.1 to loiter in that tiny little garden i showed you - yes, 3m*3m, 1 metre off the ground, great fun, and it took some weird and wonderful tuning, but I suppose it's almost irrelevant now :)

Guys, I'm sorry, I know this is a bit off topic, but for those of you who fly or have flown more than one type of multicopter, with approx. same dimensions, a hexa or a octo has any kind of benneficts compared to a quad besides heavier payload ? Thanks.


So does this version use the software filtering of the accel and gyros in order to reduce the effect vibration has on the sensors?  I believe that's what I read in the GIT, but I am not entirely sure.

yeah they look cooler..

:) yes but I would like to know if regarding stability they are more stable or doesn't show great difference. I think there should be some difference because there are more motors trying to stabilize, but I 'm not sure since I've never seen one "live".


Absolutely more stable, Rui!
Just watch my videos with quad and octo, you can see a lot of difference in stability.
