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.
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!

Anybody else have a situation where, after booting up, the first time you arm the motors, they stay armed for some time less than a minute, and then disarm for no reason. When you re-arm, it then stays armed.
Not a problem for a heli thank goodness. I think it's just my APM board is messed up, but just checking.
@Robert: I have the same automatic dis-arming issue :) Running apm1 with 2.4.1
I'm not sure it's an issue. Sounds like a safety. It also happens here- 2.4.1(w/ DCM fixes) on APM1. (2.4.1 is flying awesome, BTW. I've taken some tips from Marco's parameters on tuning the Loiter_lat, lon values.)
I may be wrong but I remember sometime ago, a talk about a timer to auto disarm if motors armed and no input for 30 sec.
I have alos noticed when waiting for GPS lock , the blue Light on the media tek that says 3D fix goes solid a LONG time before the APM says GPS solid . any one else getting that ?
The blue led on mediatek goes solid after fix, not 3d fix. The board led stays solid after achieving 3d fix, that usually occurs a while after fix.
Do you have xbee's? If so you can watch the flight data, it tells you when you have a gps lock and 3d fix. Bizarrely my apm1 gps light keeps blinking even after i have a 3D fix. Seems still to work ok, I've got 2.4.1 in the air and am tuning a reasonable loiter :) I'll check it again shortly.
this new motors test does not work for me. first i have a APM 1 setup in X... now when i start the motor test motor 1 spins fast.. not like in the vid then motor 3 spins fast and dont stop.... i did test this last week with the old motor test and it was ok....any help
glenn: you're using 2.4.1 from the MP? I just tested the motors command and it works exactly as described in the wiki. Each motor spins slowly for a second, in order. Are you trying on a quad or something else?
ya i have a quad, if i run the motors with the radio they do spin the right way... just the auto test thing dont work...
Have you calibrated your ESCs?
Yes i did... i guess i will try to reload the software and reset it all up..
