Hi,
i need help to confirm if i have now a faulty ESC - i got 2rd (rear left) motor to melt previously, for reasons unknown - very odd, so i replaced all motors on the bird. i then ran an autotune, all seems fine EXCEPT that now upon giving max speed, of just forcing drone to go above certain speed i get a consistent yaw rotation (clockwise, i think) happening. it did not do it before, ever.
while in simple mode it still maintains correct sense of the direction - so i presume compass is not really affected and yaw is not mag induced, and the log analyzer agrees - mag interference is 21% or so, not too bad.

If anybody could find 5-10 min to take a look at this data and may be see something - i would really love to understand what causes that yaw rotation now - i had there in log a pos.hold back and forth movements and a straight up movement in stab mode - that all causes yaw rotation now.
ESC is the Holybro Tekko32 35A 4-in-1 BLHeli32 3-6s ESC, updated to latest blheli32 code,
which is a pity it is went bad on me.
i would really like to confirm that it is indeed the ESC before trying to swap it out. thx!
