ArduCopter 2.4 released
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.
Enhancements:
- massive reduction in memory use (>2k saved!) due to Parameters change and APM2 baro lib fix. TradHeli code can again advance in hand with the quad code
- improved throttle range in stabilize mode. You may find that it takes slightly higher throttle than previously during hover but hopefully you'll find that you have more useable range of the throttle stick as well.
- added TUNE_LOW and TUNE_HIGH for CH6 Tuning (I.e. to set tuning range between 2 and 6 set TUNE_LOW to 2000, TUNE_HIGH to 6000)
- new ACRO_P gain for those who like to fly in ACRO (aka Rate) mode
- Loiter improvements including scaling of X speed
- Easier to use motor testing. see the videos for quad and octa-x-coaxial.
Bug fixes:
- remove unnecessary block for next GPS value before saving home loca...
- remove wobble on take-off
- turn off camera pitch control (which uses channel 6) when using cha...
- reduced rate of decent when landing using sonar
- Add support for CH_10 and CH_11 for APM2 users
- fixed Log_Read_Control_Tuning so that it doesn't read too many bytes
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.

Yup, very slick. Drill holes large enough for the hose OD, and insert the little hose pieces.
Then attach those stud things, and push the plate down so the studs do into the hose pieces. The hose is now locked in place, and provide the damping.
Sorry to keep barfing out ideas. Just brainstorming.

So silicon it is then?

And those little studs look an aweful lot like helicopter canopy mounting studs cut down.

Just APM1 atm, but it's in prep for my v2 - are there any in the UK yet i wonder?
I'm not using tubes like above, although that's a nice idea, but grommets, they are 12mm OD, then 1/3 of the way down they have a 2mm deep by 0.5 mm wide channel cut out, the bottom of the trench of which has an 8mm OD.
I just opened up the holes on my stock ardu plate to 8mm, popped them in with a bit of silicon grease and some shiny new washers also greased up and i think i could sit it on the washing machine with little protest...

Auto-Level not working in 2.4/2.4.1
Could somebody else please try this before I report it as an issue? I have done this several times now, on my QuadPod indoors a few times and just now on my 3DR outside when the wind dropped enough, disarmed it and then changed the battery. Every time it seems that auto-level inputs a correction that is at least twice as much as it should be. On my 3DR, when I plugged in the fresh battery, my artificial horizon in MP had a distinct lean, and it flew as if it was completely untrimmed as well. I did a manual level in MP so it is sorted now for my frame for the moment, but auto-level is a great tool, wind permitting. Cheers, Bill

Hey Guys,
just loaded the GIT 2.4.1 code in an attempt to trouble shoot the compass problem that was causing the slow yaw I observed yesterday on my initial 2.4.1 flight loaded from MP. I still have the same issue on MP Flight Data display: everytime I connect to the APM, it starts off at north then slowly creeps clockwise to S. I decied to do the compass test from the CLI and all I get when I try this test is "not healthy not healthy not healthy not healthy not healthy", any clue what's going on?
