Hello everyone, MP 1.3.75, Cube Orange, Battery 12 400 mAh, 22,2V, 6S , Quadcopter Tarrot xs690, props Falcon 17*5.8", GPS HERE+, the weight is 5 kg, t-motors 4014 400 kv
First successful flight today!
I seem to have a vibration problem.
Sometimes the drone starts swinging and it goes away quickly.
This doesn’t seem to happen in RTL Loiter modes.
I was hoping someone could take a look at my flight log and see if there is anything that looks too wrong. Help me understand where is the problem? vibration, motor calibration, ESC, props?
As for the power supply, do not look at the errors, I eliminated them after the flight on the advice

tlog file after access control remove
That link has access control enabled. Remove that for help.
That’s a Tlog, need the .bin flight log from the flight controller.
Thanks, will send .bin later
You have a very large mechanical Yaw bias on this craft. Most likely from motors not being level. It’s commonly seen on these frames with round arms.
And the tuning is poor. It doesn’t look like you have not followed the Initial Tuning Parameters guidelines. Connect to Mission planner and use the Alt>A plug-in and make those changes.
You need battery voltage logging at a minimum for the thrust scaling parameters to function. Fix that.
Auto Analysis is not up to date and mostly useless.
Thank you very mach! I have your plan of setup.
I had aligned the motors and arm of the quad.
Is it necessary, before updating the parameters as you advised, to re-calibrate ESC, motors?
No, you don’t have to do that.
Good afternoon, I started today.
The wind was 7 m / s, so I tried to control in loiter mode, sometimes switched
on Stabilize. The drone hung steadily in the air and tilted correctly when moving. There was no previous swing, like last time, even with such a wind. The ascent and descent of the drone is smooth, the motors start to work at the same time after the ESC calibration. Besides balancing and vibration of motors, what else can be improved?
I understand that my drone balancing is not perfect, I will have to think about how to improve it.
Do I need to set the parameters (MP tip after Alt-A, ATC_THR_MIX_VAN = 0.5 PSC_ACCZ_P = MOT_THST_HOVER, PSC_ACCZ_I = 2 * MOT_THST_HOVER) ?
Thank you very much for your help, you give me hope.
Yes, you can set those parameters but your Tune is not good. You should configure the Dynamic Notch Filter then tru Auto Tune or manual tuning. Set INS_LOG_BAT_MASK to 1 and make a short hover flight in AltHold and post that log for Notch Filter configuration review.
Today I flew in AltHold mode for 5 minutes in a light wind, I had to adjust the flight to hover over one point. The drone hovers and moves in the wind - very beautiful. My only not smooth control of the stick spoils the whole picture. Please look at the flight analysis, what would you advise further to improve flight stability?
Thank you very much for your attention.
Best regards, Sergey.
OK now eneable this and refresh the parameters and set the rest:
Then set this and make another short hover flight to check if the filter is set correctly:
What difference can I see in flight for INS_LOG_BAT_OPT,2 ? what to expect?
No difference in flight. This simply logs the post filter data so we can see if the notch filter is working.
I made refresh parametres. Why I see INS_Notch_Enable =0 in Parametr List? This is correct ?
I undestand - this is Static Notch now =0 we don’t use it now
I made two flights. I made changes before the second flight -INS_LOG_BAT_OPT,2. Unfortunately, I didn’t think that the controller would write this data as one file.
Please see what happened. I look forward to your comments.
I like to fly.
No, you really needed to make one flight. The Notch filter is working but there is still a prominent spike ~120Hz. It’s attenuated but still there.
Either make another simple AltHold Hover flight or call it good and fly and have fun.
Please tell me what reasons can cause such a noise burst at a frequency of 120 Hz, according to your long-term experience?
