"You were flying that all in manual, so no auto, loiter, position hold?"

"Can you share your PID settings for YAW?
Thanks."

"Hi Erik, I see it like this:
Along the X and Y axis the quad needs to tilt in order to manoeuver around. Those system immanent and necessary movements you don't want to see on your camera, so you need at least to stabilize those two axis.
Yaw…"

"Hi Justin,
I did not know that the controller will have an influence on yaw stabilization even if I don't touch the stick. So the control loop depends on the controller settings?"

"Can you read out the temperature from your log?
Somewhere in the the barometer values there is a parameter baro temp. I would be interested in what that says in case of your flights."

"In addition. After I build up confidence, I started checking out the fail safe modes. In real conditions.
Switching off the transmitter, simulating loss of signal during a mission and during position hold mode.
Guess what. Works fine. No crash, it…"

"Hi Justin,
post your logs and we will have a look at them.
There is something wrong with your soft- or hardware. My best guess is if you don't replace some of the components or software you might have troubles again and again.
It won't help you, but…"

"Do you know what exactly the difference is between the yaw management in stable mode vs. loiter/pos.hold?
I guess in GPS modes the heading of the GPS will be taken into account which then leads to those twitches, which we see less in stab mode? I…"

"I forgot to update on the 433 Mhz telemetry.
Had some issues with the range in the beginning. In the meantime it turned out that it was mainly due to the reduced output of less than 10 mW, which was the standard setup.
Turning it up to max of 100 mW…"

"Ok. Will try stable mode as well. But I like actually the position hold to get better moves when i.e. climbing up.
I guess there is a way to activate pos. hold with a manual yaw like in stabilize. That could then be another simple way to get…"

"Update:
Still happy with it. In the meantime I installed the Tarot Gimbal.Today I tried out some failsafes in real life condition.Switched the transmitter off during an auto mission. The Iris+ did as she was supposed to - continue the mission.I also…"

"Isn't there a log for the temperature? Under Baro there is a point Temp.
I checked one of my log files and it reads temperatures between 38 when powering up and around 45 after the flight. Doesn't look concerning. I believe it is in degree Celsius."

"And if overheating would be a serious issue, I would be keen in knowing it. I am flying in a hot and humid environment. So far each time only two battery packs in a row, without issues."

"Does anybody knows how to interpret the fact that the RCout to the ESC went down?
Will the log show such behaviour in case the ESC overheats? My best guess would be if the RCout signal goes down, it's coming from pixhawk, thus from the software."
