"Without knowing what exactly caused my problem, I found the "solution".
Started right from the beginning.
Flashed the APM mini and calibrated and (auto)tuned everything all over again.
Flies fine now..........."
"EDIT:
By "mirroring" I mean that the NTUN.DPosX is the opposite of the NTUN.DVelX value.
I've (re)calibrated the external compass and autotuned the copter. GPS had 9 sats."
Hi,I have a weird behavior in loiter/poshold.When i'm loiter and I want to yaw my copter, it's drifting backwards for about 3-4 meters and than will slowly go back to it's position where it started from.Doesn't matter if I yaw right or left. It…
"Wow Randy, I'm learning a lot here......
Never to old (67) to learn, lol.
The Pixhawk is powered by a seperate bec (not by esc)
The Pixhawk is supplying power to only the FrSky RX and a 433 mHz module (for using Tower app).
The 433MHz 100mW module…"
""for example, are the ground wires from the ESC connected to the pixhawk's top rail"
Randy, I have all the esc GND wires at the top of the Pixhawk and the signal wires at the bottom.
I sense that you have more options for this problem.
Can you…"
"Thanks Randy for investigating my problem,
It's a bit hard for me to understand your explanation(s), because I'm not a programmer .(just a fanatic diy man)As far as I can follow you:Is it most likely the esc itself that's causing the spike?Do you…"
"Never heard of it either.
In the log I can also see that there is a huge spike at the end on motor #1.
But..............what is the cause if this spike?
I don't want this to happen at 50 meters high!"
"Yesterday my Hex (with PixHawk fc on AC V3.3.3) crashed.Luckily, there was not much damage. One prop and I lost one of the dampening balls of my gimbal.The hex was in POS_HOLD and I was decending slowly by lowering my throttle stick.When it hit the…"
"FINALY got it working your way:
"Signal wire of LG is in port AUX 3 of Pixhawk.
RC11_Function is 29 (LG)

"Think I'm loosing my brain by now.
The only way it's working is in MANUAL MODE.

"Hi Niels G.
I have it working this way also, but "auto" isn't working and should be when in "landing/RTL and/or auto flight".
Auto retract and deploy is implemented in AC 3.3.+
So my problem still is there.
Manual controled YES, auto controled NO…"
"Finaly got to do some testing..........
Still no luck though :-(
Please tell me how you connected everything.

Is…"
