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!
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.
Thanks dave. wish me luck.
Bon voyage :)
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.
... and the winner is........ the quad of JL! :-)
Nice loiter bro!
He is always a winner with his video's!!
Great job, as always ;-)
Very nice !
I can't do GIT, could you be so kind as to email me the firmware you used ?
I need to set up a friend's quad, might as well do 2.5...........
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 ;)
