"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?"

Hello All,I was playing around with the camera stabilization features in 2.45 and wanted to know how to adjust the end points of travel as well as the angle rate. Outputs 5 and 6 work perfectly fine…Continue

So I finally worked up some courage to go outside in 120F heat and test my loiter and RTL modes since I was so impressed with the stability of the 2.45 code...it really is a much bigger improvement…Continue

Ihab Ali replied to Randy's discussion ArduCopter 2.4 released"So I had similar issues JL, and since I was loading the HIL firmware through MP I didn't really ahve to reconfigure anything in APM_Config.h. The problem was that the AeroSim plugin included with MP didn't get recognized by AeroSim…"
Ihab Ali replied to Randy's discussion ArduCopter 2.4 released"Very nice JL! so this fix is basically going to be in the official 2.4.2 release once it comes out?
Sorry for the repeat question but there have been many posts and I got confused: Can you please also confirm that loiter is now…"
Ihab Ali replied to Randy's discussion ArduCopter 2.4 released"So compass problem now gone with 2.4.2?"
Ihab Ali replied to Randy's discussion ArduCopter 2.4 released"Hey Randy...thanks your replies
The "not healthy" issue was something unique to on the 2.4.1 GIT loads that I've done...I haven't seen it on the MP version or seen it again since i reloaded again from GIT. I can confirm there…"
Ihab Ali replied to Randy's discussion ArduCopter 2.4 released"yeah I understand...didn't make sense to me either but I also changed my declination from east to west(same value but negative) and forgot to mention that...could be a combination of things...but the fact is it doesn't yaw anymore and…"
Ihab Ali replied to Randy's discussion ArduCopter 2.4 released"Did you try waiting a couple of minutes before the first arming(basically until the compass stops rotation on the display)? I just tried this a few times and it consistently works everytime. Somehow got to do with arming the copter before or…"
Ihab Ali replied to Randy's discussion ArduCopter 2.4 released"Cool...thanks Marco...Now that I got some good night sleep I was able to make more accurate observations: the compass reading always starts at N and moves -50 degrees and then stops at 310 degrees. If you arm the copter in the meantime, the copter…"
Ihab Ali replied to Randy's discussion ArduCopter 2.4 released"but does this reading keep moving? so on the flight data tab it would start at north then it would constantly move..."
Ihab Ali replied to Randy's discussion ArduCopter 2.4 released"Paul I have the exact same issue...do you mind going into CLI and going into test>compass...see if tells you "not healthy""
Ihab Ali replied to Randy's discussion ArduCopter 2.4 released"loaded 2.3 from AC downloads...compass works fine in CLI test."
Ihab Ali replied to Randy's discussion ArduCopter 2.4 released"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:…"
Ihab Ali replied to Randy's discussion ArduCopter 2.4 released"Just tried that...compass off, compass on, declination, declination 1.45
still when I connect...it always starts at north and slowly creeps to south...compass stationary on my table and nothing metal or magnetic around it
i'll…"
Ihab Ali replied to Randy's discussion ArduCopter 2.4 released"Yeah it's on, declination is set correctly...now that I check on MP...something very strange...I connect with MP on the HUD page...compass starts on N then I after 10-20 seconds it starts to drift in the exact same direction I…"
Ihab Ali replied to Randy's discussion ArduCopter 2.4 released"Hey Marco...so you think this yaw issue maybe related to the MP vs GIT versions of the code?"
Ihab Ali replied to Randy's discussion ArduCopter 2.4 released"Hey Guys,
I figured out my problem...had a couple of bad servo cables that were causing some sort of a short, as soon as I replaced them everything worked fine...sorry about the earlier post.
Now on to flying 2.4.1: All I can say is OMG!!!! I…"

Arducopter 2.3 tuning Stab_P for Nav video scenarios
Posted on February 6, 2012 at 9:30pm 9 Comments 2 Likes
Hello again everybody,
Round two of "organized testing"...today I decided to keep my Nav settings from last time(see previous blog post) and only play around with the Stab PID parameters to see what kind of effect they have on Loiter. I started off by increasing my Stab_P from 3.5 to 5, then to 6, and finally to 7. I noticed a significant improvement…

Hello,
This is my first blog(and I mean first ever anywhere) so please excuse the lack of the "bloginess" quality :)
I've been in testing mode with APM1 since the release of Arducopter 1 code. After a couple lost and crashed quads, I decided that my strategy for testing arducopter from now on is to start with a cheap frame/motor/prop combo, basically to…
