Drone log analysis for smooth flying

Dear All,

Thanks for making this wonderful community.
I am building the hexacopter drone and having some problems in making it stable.

I want to know you all experience guys feedback on it.

I have done the flight in Althold mode and found the drone is drifting away faster without any pilot stick, I done the log analysis and found out that anticlockwise motors are running faster.

This is the log link for your reference: 2025-03-25 08-35-22.bin - Google Drive

Logically all motors are run almost same in Althold hovering. I think this is related to some leveling problem. But I want all your opinions and if this is the leveling problem then I did my best to do the motor and level calibration and I don’t know what more I can do so please suggest me the best way for motor leveling.

Really looking forward to hearing back from you all.

Thanks

@Vkk01 welcome to the community.

ALT_HOLD mode will hold the altitude, but not the position. The vehicle will drift in the wind. That is normal and expected.

Continue to follow instructions and tune the PIDs. After that you can start using loiter mode that does hold position.

Hey @amilcarlucas

Thanks for the quick response. Yes, vehicle should drift in the wind but I flown in the No wind environment and it was drifting very fast.

I am expecting it is more of level calibration, in Althold with no wind it should not drift that fast.

It is not the CG issue because anti-clockwise motors are running faster than clockwise.

Dear,

I hope you are doing good.

I am unable to solve this leveling issue, so I moved to the tuning phase.

I have tried the tuning and it seems the roll tuning was successful but for the pitch tuning, the drone went into the loop and it did not finished the tuning. I need to stop it as it was again and again doing the same tuning.

Here are the logs, can you please check it and give your feedback on the tuning:

Hey!

I hope anyone will see my posts and help me out in figuring the issues with my drone.

I have done the auto tuning and found the result very sluggish and not smooth at all.

One more thing, for the compass calibration, I have drawn the 8 figure and using magfit tool. Can anybody help me to do the compass calibration as well?
