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.




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.

Thats why the hash is relevant. Not to worry though...

Ok then, just nobody mess with it in the next five minutes ;)

Ok Robert i agree, next and this time i put the hash for reference!

Marco, you gotta get a dog to play frisby with. ;)

Today there a dog at the airfield and I had to stop testing because he wanted to bite the quad on the fly! :P
Freesbee launch is a nice blow for electronics and software, if the quad can return to where it means that works well.

I had a very interested husky at the park the other day, i let him sniff around as he seemed a friendly chap, however when he cocked his leg at my quad I had no choice but to give him the scare of his life... it took a while to stop him barking...  

Oh and before you hit the hay Marco, any chance of your params in that vid?

Many thankings

Sure Dave but i'm sorry, don't have the quad here, tomorrow i upload here!

Yes. Also generic GPSs in NMEA mode, although we don't test and certify them.

Oooh really, I've got a NMEA holux unit that i used with my phone before i got one with built in gps that was accurate to about a meter 10m inside the main doors of a shopping centre, It knows when i swap from one sofa to another, and its bluetooth.

Here a video of a test flight of the latest firmware ArduCopter v2.4.2 (beta) with the new fix on DCM and the magnetometer setup. This version tested in flight include also the AUTO-LAND and Helicopter type H1 (HIL) mod XP2 (JLN).

Wind: 15 Km/h from N-W

The LOITER (baro only) is very stable in spite of the wind and there is no drift in the yaw. The flight is very stable.

Stay tuned, this new version 2.4.2 will be soon on line for download in the official repository...

Regards, Jean-Louis

Hi JL, do you know if the repository version will have your auto landing mod ? Thank you.

I was making a small test about 1h ago and loiter is without a doubt much more stable and willing to hold position. Strange though, how you having a lighter and smaller quad than mine (with higher thrust/weight ratio), you can still use LOITER_LAT and LON P so high, mine at 2.8 still overshoot a lot, I had to lower it to 1.5 and will try 1.7 tomorrow.
