So today I was flying my S800 hex with APM 3.1.3 and pixhawk, I did 3 short flights. The purpose of these flights was to test my new gimbal. For gimbal control, I'm using mission planner, 3DR data radios, and a PS4 controller. For flight i'm using a taranis Tx with dragonlink UHF module and a 12 ch receiver. The Tx and Rx have passed a range check, so I do not think a receiver failsafe was activated. I did not have the battery options properly set on my laptop, and after some flights, after landing I noticed the laptop was asleep. :/ Not sure if thats related, but worth mentioning I guess.
The first flight, I noticed the heli seemed "twitchy".. like it would fly smoothly and suddenly twitch in one direction regardless of my input. I landed.. the motors and esc were all normal temperature.
The second flight went smooth, and without error. I landed a few times to adjust my gimbal.
The third flight.. towards the end of my flight my heli became unresponsive for about 1 second. It began to gain altitude and then control was re-gained and I was able to land safely.
I've never had problems with APM before, so I've never had a reason to read my log file. Today I am trying to learn to understand the logs but it is very overwhelming for the first time.. I'm not sure what to look for. I notice in log 46, ctun, towards the end of the flight, throttle out becomes very erratic, while throttle in remains the same. I'm not sure why this is... Also, In log 48, the last flight. my log file seems to end before I ever land, like the log stopped recording? Is that right?
Anyway. I'm pretty lost as to why my copter is behaving like it is. Any help would be really appreciated.
