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.
I tested 2.4.1 this afternoon with little wind, personal configurationX: weight 1542g, 600mm oc, 880kv motor, propeller 12x4.5
Pid with normal
Stable: good (setting a polish up!)
Hold Atl: really bad (suremment setting a polish up!)
Loiter: impresive! very stable with slight drift crosswind but the wind is in 1m2
unfortunately I could not use because of problems APM1.42connections?? (working at home?)
presence of a high voltage line is this the problem? in your opinion?
good evening to all
We need DMP on AMP2 as soon as posible....
digital motion processing. My understanding is that the new MPU-6000 sensor package on the APM2 supports it, but that it requires software licensing from the manufacturer to enable it.
Guys, we missed 2.4.1 from the downloads section. It never got uploaded before new changes when in for 2.4.2. However, I managed to find it, dust it off and upload it for you. ;) You can download the 2.4.1 zip if you want. It is pure 2.4.1 and does not contain any of the changes that have happened since. It's exactly the same as what you get from MP currently.
ArduCopter V2.4.2 (incoming, daily GIT fix of 2.4.1) - Loiter improvements test:
My daily video with loiter test, after some improvements by Jason Short and Andrew Tridgell.
Now NAV parameters not affect the quality of loiter.
I also tested "unwillingly" the solidity of the i2c bus, flying for a few minutes without a compass with the i2c bus in shortcut due a little bastard microball of tin.
My loiter parameters:
LOITER P: 0.2
LOITER I: 0.01

Yes, very impressive, no overshooting, let's hope this can be replicated by all of us :) Jason, Marco and all the devs congratulations.
Oh, now that is truly lovely!
The errors just seem to be purley gps based, when it gets where it wants to be it stays there! It's got the same sort of pattern i see on my traces when my quad is sat on the ground!
And hilarious proof of point frisbee Marco, and i see you have the sonar working well. Great stuff.
Did you try with just baro? I'm finding it tricky to get back to 2.3 levels of alt-hold without the sonar.
Any chance i could try this out then? At my own risk of course ;)
By 'mistake' do you mean that the slight (very slight) wander is because of GPS wander, or that I'm mistaken and it's something else?
Maybe all we need now is a tuning guide and support for the dji gps unit ;)
