And, you will also read about simulator trials where the aircraft was taken off, with full NL rudder trim, and how difficult this was for the pilot to sustain.
Actually the report says:
" The yaw on take-off was manageable......After takeoff the aircraft was manageable but challenging up to about 140 knots..."
The aircraft didn't get above about 112 kt. So, on the ATSB's own evidence, the yaw from full LH rudder trim was manageable.
