"I'm running an APM2.0 so I haven't bothered with foam on the barometer. Maybe in vertical climb the barometer is picking up a higher pressure?"
Looks like I'm getting some altitude overshoot that causes the throttle controller to oscillate. See log graph below. It's most noticable when I execute the Takeoff 20m command but I can see evidence every time the copter climbs to a programmed…
"Wish I had your weather!
Maybe something is resonating depending on your banking.
I had my electronics stack cover do wierd resonances once....
I assume you ruled out the easy stuff
1. Loose motor
2. Bad motor bearing (Hint: Use CLI "motors"…"

I noticed with my quad, normally, all the ESCs give out the 123 (self test) then 3 beeps (3S battery ) and finally 2 beeps ("I'm ready to arm").
At -5C I got a case where 1/4 ESCs gave out the double beep about 1 second later than 3/4…"

"Did you confirm your X vs + configuration and prop rotations are correct?"
"ESCs : Tie wraps
Motor wiring: Ditch the bullet plugs and direct solder . Enclose all wires in 1/2 inch plastic cable loom. See photos below:

"Welcome to the Bent Motor Shaft Club!
I didn't have much luck straightening shafts unless I dissassembled the motor. I found a little trick that seems to work for me.
1. Carefully remove the "E" Clip from the motor bottom. (Hint: Do your work…"

The ESC has a built in +5V regulator so the servo plug Red is +5V output from the ESC. see below
On the 3DR PDB your red/black cable connects to one of the ESC +5 volt output pins. The red/black cable powers the APM board. …"

Auto land does not cut off the motors but rather puts the copter into a decent. The pilot has to flip back to Stabalize and manually cut the throttle. I got a gust once and did a ground roll in Autoland mode so I like to land manually....

That happened to me once because I accidently had the throttle up high.
Did you look at the logs?

Here I thought I'd put the 'copter away for the winter. Maybe we'll start a "Nov- April North of 45" blog!!
btw your photo is fabulous. I nominate you for the drone photo of the year ...It's art! (Wait- is there a DIYdrones Drone photo of the…"

"Emile.
Great video. I presume you are still using same equipment as your vacation blog i.e. APM 2.0 (modified)?
Did you "cold soak" your equipment prior to flying ?
Here in Ottawa, I flew my 3DR/APM2.0 a few weeks ago at -5C. Seemed like there…"

Thanks for taking the time to do this. Very helpful to see what is going on with the power.

1. Caribou herd counts
2. Polar Bear Monitoring
3. Various Arctic Development jobs"

" Perhaps your barometer is getting faked by higher pressure when travelling at higher horizontal velocity. A test method to see if this is happening would be to set Alt Hold mode and fly manually at high speed and see if altitude droops during…"
"Handy trick: Go to your local hardware store and buy some rubber 3/4 inch diameter furniture feet. Push them onto the 3DR "toes" . No more snags and much more robust to landings with horizontal velocity...."
