ArduCopter 2.4 released
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:
- massive reduction in memory use (>2k saved!) due to Parameters change and APM2 baro lib fix. TradHeli code can again advance in hand with the quad code
- improved throttle range in stabilize mode. You may find that it takes slightly higher throttle than previously during hover but hopefully you'll find that you have more useable range of the throttle stick as well.
- added TUNE_LOW and TUNE_HIGH for CH6 Tuning (I.e. to set tuning range between 2 and 6 set TUNE_LOW to 2000, TUNE_HIGH to 6000)
- new ACRO_P gain for those who like to fly in ACRO (aka Rate) mode
- Loiter improvements including scaling of X speed
- Easier to use motor testing. see the videos for quad and octa-x-coaxial.
Bug fixes:
- remove unnecessary block for next GPS value before saving home loca...
- remove wobble on take-off
- turn off camera pitch control (which uses channel 6) when using cha...
- reduced rate of decent when landing using sonar
- Add support for CH_10 and CH_11 for APM2 users
- fixed Log_Read_Control_Tuning so that it doesn't read too many bytes
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 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?

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.

Here a video of a test flight of the ArduCopter v2.5 firmware (offical GIT version Revision:1ed94f0064f5) done with a F450 DJI Flame Wheel quadcopter and the ArduPilot Mega v2 board.
There was a medium wind of 21 Km/h blowing and gusting from the left. You will see that the Loiter mode works well and that the quadcopter is able to fight itself against the strong gusts. In some others tests flights, I have also tested the RTL, super simple mode and off course the stabilize mode without any problem.
Regards, Jean-Louis

Gustav - I couldn't do GIT, but its really easy, i was over thinking it.
Just follow the instructions in the wiki to install GIT and download the whole repository to a local folder on you machine as instructed.
Then quite simply copy the arducopter and libraries folders out to your arduino sketch folder, compile and upload as normal with arduino 1.0 relax patch.
As you are not going to be uploading anything in GIT you can forget about the rest of it.
It's well worth it, see my report and vid to follow within the hour ;)
