Quadcopter yaw during takeoff on ground(Solved)

I shall do that tomorrow

Attaching a photo of the mounting

Yes, I saw that already. You can try putting ear plugs into the centre of the blue silicon balls.
If you even need an antivibration mount for a Cube, and that’s a big IF, then this is the mount to use:

Your added 5Kg requires you to re-tune the altitude controller (repeat step 7.1 file 19 and 20) . That is causing your altitude oscillations.

Your GNSS is not going to like those voltage fluctuations at all. Your voltage is not stable!

So is the vertical altitude oscillations post quicktine because of low vibes/ and mount ?

Previously we have used the same mounting

Ok understood , shall repeat

Ok maybe this the issue gps still configuring errors

Not necessarily, but that’s one thing to fix.
The pitch and roll angles (AHRS_TRIM_X and AHRS_TRIM_Y) are quite important too.

All these things add up to make a big problem.

Yes, that is bad and is causing problems.

Whenever you change a component, or the weight of the copter you should do:

It explains the dependencies:

Now depending of the changes you made you will need to re-do some steps and can skip some others:

FC changed - Need to redo all steps
Frame and/or Take-off-weight - redo steps 19 and above
RC Controller - redo step 05 and the RC parts of step 12
RC Transmitter - Redo step 05 and the RC parts of step 12
RC Receiver - redo step 05 and the RC parts of step 12
Telemetry - redo step 06
Battery Monitor - redo step 08
Battery - redo step 08 and 19 and above if the weight changed
ESC - redo step 07 and 19 and above
motors - redo step 07 and 19 and above
props - redo step 07, and 11 and above
GNSS receiver - redo step 10

I just did a new ArduPilot Methodic Configurator release for you, with some corrections and additions.

How do I see the new changes that has been made any where I can see just the changes to understand

Sure: IMPROVEMENT: Updates from sauravhobyy (AirBus Pilot) · ArduPilot/MethodicConfigurator@970cac1 · GitHub

Green is new, red is old.

From the link I posted above:

The GPS antenna position is incorrect AFAIK.

Thanks very much , will read all this and then start over from step 19 and all calibrate level for ahrs then give you some updates in 2 days l.

Position of gps it’s forward facing, and AFAIK ?

AFAIK stands for “As far as I Know”.

You moved the antenna, but did not correct the position parameters in file 10

Your vehicle_components.json file is getting better, but you still have not filled all the fields.

Yes regarding this a question

My cube ap is 90* right (yaw right ) I have set in that pram for ahrs

Now when I calculate the position of gps 1 and gps 2 in reference to autopilot do I need to regard autopilot at forward facing itself since we have already told the Ap that’s its 90* right .

Assume AP is facing forward to make those measurements.

And fill ALL “change reason” fields!
