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.

Hey Marco...so you think this yaw issue maybe related to the MP vs GIT versions of the code?

Yeah it's on, declination is set correctly...now that I check on MP...something very strange...I connect with MP on the HUD page...compass starts on N then I after 10-20 seconds it starts to drift in the exact same direction I saw physically until it reaches 190 deg S... very strange, any idea what's going on?

Try to disable and enable again the compass... make a full turn with your hands to your quads and tell me if you still do.
Here is ok (latest GIT).

Just tried that...compass off, compass on, declination, declination 1.45
still when I connect...it always starts at north and slowly creeps to south...compass stationary on my table and nothing metal or magnetic around it
i'll test with GIT code but it's 4am here :) so tomorrow...will let you know

Excelente, a qualidade de imagem é muito boa, apesar de poder ali amortecer um pouco as vibrações que estão a passar para a camara :) parabéns.

Caro Rui,
Agradeço o seu comentário. A questão que colocou é o assunto que ando agora a trabalhar para obter uma imagem com melhor qualidade.

Getting compile errors with current git version? (have pulled new version (and libraries) from git, I'm using 0022-relax or 0100-relax)
In file included from ArduCopter.cpp:93:
GCS.h:129: error: 'ParamToken' in class 'AP_Param' does not name a type
ArduCopter.cpp: In function 'void update_trig()':...
Something I'm missing?

"sudden-death" lean - firm foam mounts.
Red & green lines shows sensor out, pink & green shows attempted stick correction (pink is greater as it was coming straight towards me!)
This only happened on the first flight, subsequent flights had the slow accumulating 'lean'.

The AMP-2 has a MPU-6000 Digital six axis mems motion processor, It has 4 variable output sensor sensitivity settings i.e. +- 250 deg/sec going up to 2000 deg/sec and the Accel starts at +- 2g going up to 16 g.
So my question is this. When I receive my APM-2 does it come with a preset sensitivity setting? If so what is it?
How do I change it?
