Version 2.6 of the ArduCopter code is now available in the AP Mission Planner and in the downloads area!
Updates to MavLink 1.0 means you will need to use "ArdupilotMegaPlanner10.exe" to connect. If you've updated your mission planner recently you should find this executable in the directory where the mission planner is installed.
The above video is done using a prototype 3dr ublox GPS which seems to have better accuracy than the standard mediatek.
Improvements over 2.5.5 include:
- MavLink 1.0 support (use with ArdupilotMegaPlanner10.exe) [Tridge, Craig]
- Stability improvements especially during level hover [Jason]
- throttle range improvement (higher min and max) [Jason]
- improved standard Loiter PIDs [Alan, Heino, Jason, Angel]
- dataflash erase speed up ('+' messages removed but it only takes 6 seconds now) [Tridge]
- Copter LEDs [Robert Lefebvre]
- RTL loiter stage target set to home to improve final landing position [Jason]
- flip & acro improvements [Jason]
- circle mode target improvement for ground station [Jason]
- Auto Approach [Adam Rivera / Marco]
Bug fixes include:
- UBLOX driver fixes (lock should now be more reliable) [Tridge]
- enable mavlink messages during dataflash erase which resolves issue in which new APMs fresh from the factory appeared unresponsive [Tridge]
- proper printing of lat/lon values in dataflash logs [Randy]
- removed duplicate GPS reads [Jason]
- resolve flooding of telemetry link with low-battery warnings [Tridge]
- RTL bug would land if rtl_approach_alt was more than 1 [Jason]
- WP Radius could not be set larger than 1.3m [Jason/Randy]
Tuning:
PIDs are optimised for the 3DR/Jdrones quad with 850 motors and 10" props. If you're using more powerful motors/props and are seeing bad flight behaviour in stabilize, start by turning down Rate Roll P in 25% steps.
This time we spent some time optimising the loiter PIDs. Tuning loiter can be tricky so please refer to the discussions which will appear below for more community feedback on what parameters work best.
All feedback welcome below. Enhancement requests and bug reports can be put into the arducopter issues list. When possible please include logs (tlog and/or dataflash) and tell us whether you're using APM1 or APM2 and what version of the software you're using (presumably 2.6 but tell us anyway!).
Happy flying!

I tried to run and auto pilot mission last weekend. Im not sure I have the settings correct. The plan basically was to auto take off to 5 meters then after 30 second to go up to 20 meter, then 100, back to 40 then 20 and then land. But all it did was take off to 5 meters and just stayed there.. Can someone please look at the file and let me know whats wrong with it?

Just had a look at some old logs.
This is what my mag log looks like:
Is this how it is supposed to look like?
Seems like a lot of noise to me.
What’s the LED_MODE parameter? I noticed that on 2.5 the default is 0 and on 2.6 it’s 9?
I still have an issue with GPS... I get a solid blue light on the GPS Unit, but the mission planner (connected via Xbee) does not pick up GPS signal. 0 satcount, but solid blue light... My GPS location does not show on the mission planner.
I am running APM1 with 2.6 (modified for octo quad)
Any help would be appreciated.
Thanks
Having a strange RTL issue with 2.6 : when activated, my tri always bank toward an apparently stochastic direction and maintain it's angle until I switch over to stab. I have the APM2 with stock MTK GPS, and a well tuned loiter. MinimOSD should display an arrow showing home direction and distance but doesn't, so I don't know if it's osd-related or AC having trouble to set the home point. Is there any way to tell where the home location is with telemetry and MP ?
Hi,
I have some problems with logging.
Some time is working, most the time not.
Usually I get following messages:
Init ArduCopter V2.6

I erase all and get:

After flying get again first message...
Any ideas?
I have an issue with GPS...

0 satcount, but solid blue light...
Im at a loss!
look at the video.. my problem video result still not smooth.
my quad frame X650, 2.2kg (included 4s , vtx,gopro), APM2 FC, v2.6
i use MC6500PRO camera gimbal and MP set gain set to 3 (faster response for camera gimbal)
quad all stock PID except STAB ROLL / PITCH "P" value is 3.5.
the quad seem flying smoothly.
question:
1) is it i need to lower my STAB ROLL / PITCH "P" value to let says 2.0? to get smooth hover/flying so that my gimbal will stabled and not to push to hard?
2) i have no idea how to set YAW setting. when STAB mode, push YAW stick slowly and quad bounce back
thanks for answer..
Just built my first Octo. Hobbyking F-30A , Turnigy SK3 3530-1150. (2)Turnigy 6000mAh. APM1-2560, with firmware 2.6
During a calm flight everythng is fine. If I bank hard, it seems like the ESC's go nuts.
You can hear the strange sound in the video

Do you guys think this is a ESC problem, flight controller problem, or something else? Any advice would be awesome.
