I have the exact same problem, with tiller in the neutral position the aircraft veers to the right during taxi. I have no combating hardware assignments, no AI assist, no throttle variation on engine 1 and 2, etc. I corrected the issue by setting/mirroring my rudder pedals axis assignment to the nose steering axis assignment. This corrected the veering issue but it’s not the ideal solution. Hopefully iniBuilds can recreate this problem on their end in order to find the proper solution. But I’m ok for now.
Unfortunately B-LDD and B-LDN registrations expired in November and May 2023, respectively when the aircrafts were transferred from Air Hong Kong to EAT Leipzig and ASL Airlines Ireland. As of 2/15/2024, Air Hong Kong are have A306F registrations: B-LD(A,B,C,E,F,G,H)
