Hallo friends.
My name: Yohanes, from Surabaya Indonesia
I am still new in this forum, but I've played a quad copter since 2 years ago.
Lastly I tried Arduino (I usually use 2.0 kk). I use apm 2.5, arducopter 3.0.1. Setup and all calibration has been successful (include compassmot only 18 % result). Quad can maneuver well in a stable mode and auto mode and rtl.
My filght mode settings are: 1 Stabilize, 2 alt hold, loiter 3, 4 circle, 5 stablize with simple mode, 6 rtl
Problem I faced was, at the altihold or automode (circle, loiter, etc.), sometimes the throttle cut off by itself instanously (in few seconds), which sometimes could recover itself, sometimes not (being crashed).
I've tried analyse the log graph, but I could not found the cause of the problem, why it could happened?.
For whom my friends who are already experienced in APM and arducopter, please help me to analyze the log data that I include (attached) in this discussion.
I very apreciate your help and hope to be able to find the cause of problem.
Thank you very much
PS: This has happened three times in 2 days in same location area.

Here's a useful plot:
-Channel 7 was activated, commanding an RTL
-Channel 3 (throttle) was set to minimum
-Channel 5 was set to stabilise shortly thereafter (to rescue the copter I assume)
Is this what was happening on your RC controller?
