Slight yaw movement

[Adrià]

Hi, I have experienced a few times a slight yaw movement without doing anything. Sometimes I am just hovering and with the mobile I can see a little rotation movement. Other times I pull the stick forward and it goes forward and a little bit to the left due to this movement. First I though it could be the wind but I tried without wind and also happens. Any suggestions? Thank you so much.

Recalibrate compass - how many satellites u locked into when this happens?

Oh, you mean like discussed previously in these threads?.....

Mavic air yaw 2019 FW .620

I had an issue with my drone yaw to the left. It yaws when ascending. Also tried to make it stationary with no issues. But when i flick the left joystick UP even just a little bit. It starts to yaw to the left. Tried restore default. Refresh firmware, imu, rc calibration and rc link. Worked...

Aircraft Yaw CW - Neutral Controller

Problem? Aircraft has a propensity to yaw clockwise with hands off the sticks Was unit in a crash? No What have you tried so far?: Full calibration in an electronic and metal-free backyard on grass (compass, IMU, RC, gimbal) What device are you using? Mavic Air RC with iPhone Xs Max What...

The Air graduated to a full 45 degree Yaw.

When I first received the Mavic Air, I test flew it out of the box with 0 (zero) involuntary yaw movements (without stick manipulation). After one of the updates it inherited a 6-12 degree yaw to the right.... I learned to live with that hoping an update would fix it.....nope....none avail. A 45...

Mavic Air yawing during flight

Hi all, You may recognise the video posted in this thread as I have posted once before but it went a little off topic, and I am still seeking some more advice. A few weeks ago I crashed my perfectly working drone and received a new one from DJI Care (DJI Refresh). On my first flight of this...

MA drifting in little wind

Hey guys, just a quick question. Got my new Mavic Air via DJI Care and all great until I noticed something this afternoon. Not sure if it is just me being overly picky or whether it is an issue. I was flying above my house at 40m and I noticed the drone turning in the wind without me touching...

Mavic Air False RC yaw signals, recalibration not helpful

Flying my Air since I got it in March. I've noticed it rotates slightly up in the air when hovering without any of my input. Also when I'm just ascending/descending and going forward, aircraft yaws without me touching the yaw axis. This has ruined many shots. So I tried recalibrating the RC...

Recalibrate compass - how many satellites u locked into when this happens?

I will try to recalibrate the compass always as I am not sure that when this happens I had recalibrated previously. Another thing, when the drone is stopped I rotate the propellers with my fingers and realized that the front right one is "harder" than the others (like stronger magnets). Is this normal? Can this cause the yaw problem?

My motors are similar - don't think the motors are the issue - you can always do a test flight and look at the data for each motor - goto a ball field and do a real good compass calibration and then see how it is - also do a controller stick calibration too to rule that out.

I will do that. Thank you Moose.

Don't calibrate the compass often. You might actually "detune" the calibration if you do it in an area with moderate magnetic influence. Once you have it right by evidence of decent flight response, leave it.

You could try IMU calibration, though symptom suggests compass.

Motor could be an issue, depending how much different it is from the rest but flight control should compensate even if it is a bit sticky. Check for debris in the motor.

You could be experiencing an issue of the compass being magnetized and needing to be degaussed. If you store it near magnets such as a speaker, that could do it.

Don't calibrate often?
Both of my DJI Mavic Air require a calibration before I can take off at least 8 out of 10 flights.
Does not matter if I move to a clear of magnetic field area or not.
Sometimes I can reboot the craft and it will be OK.
But mostly, the craft will not let me fly without it.
