I never installed this mod. ( ..of the three downloads in quote, select/install ONE: ..third one looks good.. ).
But since no one else has answered:
- I bet it is a complete aircraft.
- it has no slot, therefor it takes over completely the other mod/aircraft.
- I would not recommend having both set of files present at the same time. Remove or neutralise any previous A1H files.
- Drop in the 3 files from within one of the proposals (1of3), but do not try to install static entries of the first file , until much later.
- IF AH1 statics already exist, an equivalent/or first file of the trio must absolutely be present. Take no further action for statics.
- be sure to use air.ini entry line of the regular A1H mod ( add only if not there already ):
AH1-Cobra air.AH1 1 NOINFO usa01 SUMMER
...see in the read.txt of second file, there is also an entry line for an AI driven version.
If you ever find skins, current folder is AH1-Cobra; you can eventually rename/create UH1-HueyD skin file, using this edit instead:
UH1-HueyD air.AH1 1 NOINFO usa01 SUMMER
...don't forget to actually create the UH1-HueyD file in skins folder, after that.
...purely cosmetic actions follow...
- Add/replace into Plane.properties this edit of the info:
AH1-Cobra Bell model 205 UH-1D "Huey", 1963
...or, if a new skin file was renamed/created, only add the new line:
UH1-HueyD Bell model 205 UH-1D "Huey", 1963
...be aware a Huey-D does exist with it's own slot. Behavior, skins, sounds et.c might be different in that case.
