"Hello, now i have raw datas and can log Gyro X,Y,Z and Acceleration X,Y,Z
but what can i do with those datas to analyze the good/bad behaviour of my setup ?

"Hello before hitting "download logs", wait in the Terminal window that the APM is fully connected.
It may take some times ... then hit three times ENTER and retry clicking "download logs".

First i was also unable to download logs until i realized…"

"Thans to Redemptioner, i had a response ( On tuning guide post ).
I wil ltry to add RAW datas on logs and see if it helps."

"Sorry to "bump" the message but anyone has informations or links on how to analyze logs about bad parameters settings on Yaw or any other channel ?

Thanks."

"Anybody knows how to analyze CTUN logs or else ?

Happy new year to anyone passing by here ... ;)"

"Hello, i've just found this on the wiki : http://code.google.com/p/arducopter/wiki/AC2_Datalogging

It looks like the CTUN logs are able to give datas on gain loops.

How can i use these CTUN logs to check gains ?

Here is a screenshot of my CTUN…"

"Hello, i'm following this post and have the same question ...
My need is to use the same APM on a Quad and a plane
but outdoor season is closed for me so i won't do it this year, for sure.

But i think it's quite simple. For me i would do that…"

"Awesome ..."

"Hello, i noticed on my APM 2 that if i connect the USB and also the "main" power battery it saves a log.
For example i get a log file when i make my calibration "on bench" ...
But i don't know if there is all the informations on those logs ( i…"

"Hello,what do you mean by "overlay map is xxx ft off" ? Points on Google maps are wrong ? misplaced ?
I also noticed i have a small offset on Google maps ( 5 to 10 feets maybe ... ).
If you think your GPS is right but the Google maps is wrong just…"

"Hello, everything is OK on second flight. No offset ...

"Hello i tried to find information a few weeks ago, too.
Here is the link on the wiki : https://code.google.com/p/ardupilot-mega/wiki/APLimitsLibrary
It's only a simple circular fence and an altitude limit that can be set with the parameters list on…"

"Hello. For problem 2, just know that you can "manage" motors rpms without using the APM
just only with your transmitter and "all the motors" leaded to the same "signal".
In a heli model on your transmitter you can use throttle curves ...
In a…"

"Hello, and what about props on the datasheet ?

40A surely means the motors have a certain output power, like 500W so they recommend a 40A,
just to exploit all the output.

If you use a very large prop with high pitch, the 20A will surely have…"
