I saw your conversion yesterday! Very, very nicely done!
DH-106 and myself talked about giving that airport a face-lift hehe... (well I suggested it seeing that he does the same to all his TF1 aircraft models) but of course it's totally up to him if he wants this released... and from what I know he's having a little break from TF2 at the moment. Hopefully he'll be back very soon! I am also waiting for a reply from him.
Personal use is always of course permitted but I haven't been able to convert it myself in the past... so if you want... in the meantime you could send me the mod in the .zip....by priv message LOL...pretty please! that would be awesome!
