Problem with configuring APM and absolut unstable Loiter

Hi i´m new with APM and i have big Problems to calibrate APM

in Stable Mode or Alt Hold the copter is absolut perfect to fly.

but in all other GPS Modes…like Loiter it fly like “drunken Elephant”

what i didn´t understand…why my IMU and MAG is everey failed.

I have now Reset APM to default…and complete new installed…but in the new Log (not flying this time) it shows me Errors

what to hell is wrong?

please help…before i throw it in garbage

APM is an under powered flight controller and logging is set low. You need to set logging higher so that there is information that can be analyzed. … og_bitmask

Yours is set to 894 and needs to be like NearlyAll 45054.

Then run the test on the log and you will get more information.

Set the logging back when everything looks good.



the last days i have do all clear…downgrade to older FW…and do complete new calibrate…

i load Frame Config for “Camera Plattform”…and do yesterday testflight.

yesterday it was looking good in flight…but i dump has forgete to prgramm “Autotune” to Channel7…lol
