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…"
"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…"
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....
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…"
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…"
" 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...."
