According to a post on HPG’s Discord, the H145 V1.00 has the keyword “Helicopter” in the aircraft.cfg file instead of “Rotorcraft”. For now, you can edit the file manually, looks like future versions will have it fixed. Have to do it for every Livery you use.
I am quoting the Discord post:
The file is
aircraft.cfg. It’ll be in every livery. The line in there isui_typerole="Helicopter". It needs to becomeui_typerole="Rotorcraft".
