Yaw Inconsistent 155 degree
I have a octacopter prop size 30 inch
When I fly my octacopter on stablize mode it’s continus yaw
CCW Motor high pwm
Cw motor low pwm
Check list
All motor are level 
Radio trim in middle
Radio calibration
Motor test success all motor are rotate in same pwm
Issue
Ahrs unhealthy
But I don’t know it’s really ahrs issue
Log file
Search this forum for “yaw imbalance”
Yes I also search on it and I do any possible solution but error isn’t solved
That why I also create check list
Can you change the FC? If not them:
Backup your parameters to a file.
Use mission planner to reset the parameters to their defaut value.
Download and use ArduPilot methodic configurator software and follow the instructions.
Right away I see you need to set these:
ARMING_CHECK,1
BATT_FS_CRT_ACT,1
INS_ACCEL_FILTER,10
INS_GYRO_FILTER,20
MOT_THST_EXPO,0.77
There could be more, so run through the methodical configuration process.
That log definitely shows there is motor mount twist, or frame twist.
Apart from checking all the props are spinning on exactly the same plane, us MissionPlanner motor test to ensure all the motors are in the correct order and spinning in the correct direction.
Use the “All in sequence” button.
Also compass calibration can be improved, so when you do get it airborne do some circles, yaw, ascents and descent then use the magfit utility to discover the correct calibration.
Actually I have more than 1 copter but we face same both of octacopter
First of all that’s alot
My octa frame is EFT G20 octa
Is just like x frame
Can we put frame class + is it working well?
All your CCW props are rotating at a way higher speed than all your CW props. The CW props are going down to idle speed at times. Are these all the same motors, ESCs and propellers? Are the CCW props really CCW and the CW really CW props?
Any way you could get ESC telemetry?
Why would you use Octa + if it’s an Octa X?
@Oli1 yes all motors are same
And actually we use motor esc combo
So CCW prop fixed on CCW motor and CW fixed with CW motor
Do you have a log with Octa X?
Yes I attached with my post
The 8.bin log you posted is configured for Octa +
And update the firmware to latest Stable.
Yes brother I also send a picture of my octacopter
That frame
And also use class x
But i don’t use a latest firmware
So where is the log configured as X?
Octacopter class X logs
No it isn’t. That’s the same log.
Review the log for yourself before posting again.
Downloading and analyzing logs
I pointed out that it’s Octo + only because that’s how you have it set in paramaters.
Going by the picture you supplied afterwards it should be an X config.
