today fly after all reset default all tuning setting default
but same issue only stabilize mode work
poshold,althold,land mode going high vibration after roll/pinch rc input
Foam tape is insufficient for this craft, you need something much more compliant like a ball mount. Even Zeal Gel would probably not work but you could try it.
My 2cents…years ago we used a hex copter where clearance between props tips was 1" or less… it was horrible to land and would eratically move up and down as it neared ground…it is partially why i started building my own copters…my designs are all run through ecalcs…the x8 and quads are all ±18" square to motor center with 12 1/2 to 13 inch props… ecalcs flags a couple of these because they miss clearance by 1/2" or less… i.e. they all have 5" or more between prop tips…i have yet to see any of them have issues with ground effect… not sure the reasoning… or if this has an effect…but with the help of this community all 4 of my uavs are still flying with no major issue to date
There is a bit of spread to the frequencies though because you have some sort of weight or yaw imbalance causing motors to run at all significantly different RPM. Best tp carefully check your motor alignment.
To use throttle-based notch you would
FFT_ENABLE,0
INS_HNTCH_ENABLE,1 // set this then refresh params to see the rest
INS_HNTCH_MODE,1
INS_HNTCH_REF,0.224
INS_HNTCH_FREQ,74
INS_HNTCH_BW,40
INS_HNTCH_FM_RAT,0.7
Looking at the second log “13 fft off”, the result is the same - you would use the same throttle-based HNOTCH settings.
The broad spread of frequencies is still there, so definitely look at the motor mounts and alignment.
If you can fix that you would be able to refine INS_HNTCH_FREQ and INS_HNTCH_BW
No matter which HNOTCH method you choose, set this in all cases INS_ACCEL_FILTER,10 (I see you did this in the second log)
There must be something in your log it doesnt like. You will have to use the MissionPlanner FFT graphs for now, but ensure you have these settings for future flights
I have done that and started auto tuning my drone, the aggressiveness was 0.05. But it crashed.
Then again repaired it and trying to manually tune the craft. @xfacta@dkemxr can you help me with this.

Kindly help. It was almost again going to crash. Suggest something.
