I build a S550 drone with Pixhawk 2.4.8(unbranded one)[The Firmware version of the FC is fmuv3 4.4.4
] and Now my drone flips at take off. The motor order is correct and I can clearly see one side of the drone don’t get enough thrust than the other.Please help me with this
here is the last .bin file

and I went through auto analysis in Mission Planner and the result was as below

The other componenets that I’m using are
Sunnysky 2212 980kv motor
40A skywalker XRotor ESC
5000mah 3s battery
Tx Flysky fs i6s.
I don’t use any telemetry module.
And also I need some advices to setup MOT_SPIN_ARM, MOT_SPIN_MIN, MOT_SPIN_MAX parameters also. And my internal compass is showing and error so I had to disable it.My external compass is UBLOX M8N GPS.As I said before when take off my drone flips and I can clearly see the thrust generating in one side of the frame is lower than the other. And also I would like to know the difference between HEXA X and HEXA CW X frame beacuse my esc wiring is according t HEXA X frame. The Firmware version of the FC is fmuv3 4.4.4

Please Help me with this.

Do not use the auto analysis in Mission Planner.

Go through Methodically tune (almost) any multicopter using ArduCopter 4.4.x instead.

I don;t have much knowledge on analysis
do you have any idea why my drone flips accroding to the above .bin file @amilcarlucas

4

Follow the guide, edit the provided .param files and post them

The motor order, or the AHRS_ORIENTATION is wrong

5

OK I will do it and let you know

@amilcarlucas
my motor order is correct and I have mounted my fc arrow to tha same direction that frame arrow direction

do you have any idea on my orientation error @amilcarlucas as per above charts

Massive yaw imbalance!

Fix it, there are many threads in this forum explaining it and it is mentioned on Section 1 of the Blog post I posted. Have you read that?

9

Not yet. I only had a quick look. I will read it clearly now

10

Will it cause the flipping

Make sure AHRS_ORIENTATION is set correct in the full Parameters list !
Just because you have the Fc arrow facing forward doesn’t mean the Parameter has the correct setting listed !
Also make sure motors are spinning in correct direction and make sure you have the Props on in correct order!
Fc orientation, motor direction and props in correct order are usually the only things that will directly cause a flip over on takeoff!
Check your compass direction is correct in Parameters list if you have one and make sure it is calibrated correctly!
Good luck and safe flying to you!
