The XPFW aircraft do not have exterior objects, only interior VC objects. You are likely exporting the acf as an OBJ and comparing that in Blender/AC3D, claude181. As Michael has stated and credited, his files utilize the exterior objects from Hiroshi. Permission for this has clearly been granted and shown. You are suggesting that the FLIGHT MODEL obj (.acf file) is likely copied and made for his aircraft, and is in violation of copyright. Perhaps this is correct, but I'm going to throw a wrench in this one... As the founder of XPFW, and a person who knows the people at XPFW all on a face to face basis, I'd say no one cares that the aircraft file was used from 2008. That SAID, credit should be given, so if such is the case, Michael, please consider making that part of it right. End of story. We don't need to debate and point fingers in here all day. Lord knows the community could use some free aircraft that make the sim look better anyhow.
