ArduCopter 3.0 is ready for widespread use. To make the transition easier, this time we are asking people to voluntarily upgrade from 2.9.1b for the next month or so before we make 3.0 the default firmware downloaded by the mission planner. The new version can be found in the Mission Planner's Beta firmware's link, firmware.diydrones.com, GitHub and the new Downloads Area.
Warning #1: A bug was found in the FENCE in which if you lost GPS it could lean at extreme angles as it tried to maintain an invalid position. This is fixed in AC3.0.1-rc1.
Warning #2: This release has not been fully tested on Traditional Helicopters
Warning #3: GPS glitches can cause sudden and aggressive position changes while in loiter mode. You may wish to reduce the WPNAV_ACCEL to 100 and Loiter PID to 0.2 (from 1.0) to reduce aggressiveness.
Improvements over 2.9.1b include:
WPNAV_SPEED, WPNAV_SPEED_UP, WPNAV_SPEED_DN, WPNAV_ACCEL allows configuring speeds and acceleration during missions
How to upgrade:
1. Make sure you are using Mission Planner 1.2.59 or newer.
2. Click on the MissionPlanner's Firmware screen and click the "Beta Firmwares" link on the bottom right. The version numbers should update to "ArduCopter-3.0.1rc2", then click the appropriate frame icon and it should upgrade as per usual.
Note: Nav parameters have been combined with Loiter so do not be concerned if you can't find them.
4. If you purchased an APM prior to March of 2013, update your PPM encoder to the latest firmware.
5. Try out the new version in stabilize mode first, then alt-hold, then loiter and finally RTL and Auto.
Special Thanks to Marco, DaveC and the rest of the beta testers for putting their copters at risk during the extended testing period. Some of their videos can be found here, here, here, here, here and here. Thanks also to MichaelO for the MP changes required for this release.
All feedback welcome. Please put your questions, comments (good and bad!) below.

Please watch Randy's videos on setting up and flying APM-Copter 3.0 before you go flying. They are excellent!
Mine is 148% and it loiters ok at P0.8.Seems "fidgety" though...(not a DJI frame)
I believe Raw is now IMU with 3.0. Try "enable IMU".
Do you have foam covering the baro? Is it in the 3dr case? I've read about this happening before with regards to prop wash throwing off the readings.
With the new version 3.0, RAW is renamed to IMU. You should use enable IMU.
I moved my ESC farther away from the APM, and got it down to 87%. Haven't tried a test flight yet, but will soon.
Just checked if the motors are still working. I had still the same behaviour. Just a little throttle on the stick make the motors spin full power. So i did the following - i deleted the logs. After that, the motors are working normal again. What the hell is that?
Hi Martin. This thread is dedicated to version 3.0. You should post in the 2.9 thread for help request.
I think you did a big error, rate pitch and rate rool P gain are set to 1.0. This explain why the copter was fully uncontrollable.
Normal rate P gains are Between 0.09 and 0.15. So here you are more than 6 times higher !
Very nice, happy flying Erwin !
Mine is at 360 after rewiring it to bring it down from 260ish. Doh! It's really such a small quad that it begs for the external mag.
