NML files with GIMP and they seem to work as expected, but nothing I do changes the shininess of the objects in XP. I have also tried applying black layer masks in GIMP with the transparency set at around 30 - 35, it doesn't seem to make any difference. So, I have tried manipulating the textures and surfaces in AC3D and, in the app the objects appear exactly as I want them, i.e. I also use GIMP 2.10.32 and have become reasonably comfortable with it. I use AC3D for all my 3d development and texturing (don't suggest Blender please, I have been using AC3D for years and my efforts to migrate to Blender have been an abject failure. For the life of me, I cannot work out how to remove the shininess from my liveries. One point I'm not happy with, is the livery. I simulated a full engine failure and was able to execute a pretty good autorotation. This allows me to control the engine RPM and gives much finer control over the collective. I have a throttle quadrant, with the levers defined as: Collective, Throttle & Misture. It seems to be reasonably stable but, as most helicopters are, it is not easy to fly. I've worked my brain overtime and finished the AH-64E Apache Guardian, as requisitioned by the Australian Army, LAND 4503 Phase 1 to replace the Tiger Armed Reconnaissance Helicopter in 2025.

Thank you to for letting me know the background for the v.9.70 version: 'The S-61N was based (with permission) on the Westland Sea King HAR3 from a long time ago by s/Nils Danielsson/Ethan Teiger.' It does fly pretty well given its 9.70 roots. It's really just a project aircraft for those - as I hope to do at some point - who want to take a crack at adding a 3D cockpit to it, and do some major renovations to the passenger area.

I did make some minor changes to the instrument panel in Plane Maker: added an RMI, DME readouts, and swapped out the HSI. org account under which made this available.

I'm posting it now after discovering that the 9.70 one has disappeared and so has the previous. It is a fun model, but does reflect features that were available in v.9.70 and earlier versions of X-Plane. With his permission (see attached), I am making it available for the 11.50 community. IT HAS BEEN REPLACED IN XP12 BY THE VERSION IN THE LINK BELOW.
