Looks like you are missing a texture file. The landing gear also appear black and are probably in the same texture file.

Black in FSX usually indicates that the part(s) is mapped for a named texture that does not exist or not in the proper format in the texture folder.
There is no Mark Rooks' D-18.
There is a Mark Rooks modified version of the David Carroll FSX native conversion (with permissions) from the Milton Shupe and team's D18S gmax source and released package.
I would appreciate less emphasis on anything Mark Rooks modifies and releases of other peoples work without permissions, and many times without credits.
Otherwise, good luck and have fun.
EDIT: By the way, no offense taken here for me. I just would prefer that David Carroll get the credit instead of Mark.
Yep, same here. Nothing good comes from anything he messes with.I won't touch anything with Mark Rooks name on it.
Don't know why David didn't talk to "Mark" in the first place on this and correct him as the one who did the conversion.
That way, people like me, and others I'm sure would not get the same impression as I did.
Yep, same here. Nothing good comes from anything he messes with.
Same here, I got the OH-6 SOAR he passes of as his and found that not only were textures missing so was the instruments in the VC. Only then did I find out from post at SOH that A) his name is poison and B) he has the creative talents of a soap dish and the morals of a Philadelphia lawyer. And my apologies to any Philly lawyers out there.
Because Mark does not ask permission before he modifies or re-releases a model.
Its a long story but just ignore any further models you see released by Mark.
Roger that thanks for the heads up mate
