Yup ~ Airmail, last I checked according to my Aircrafter Utility manager I had over 4,800 Aircraft in my FSX,,,,
took me a year to get them in there too,,, 1 X 1, individually, mostly, with a lotta Tweaks to them , time consuming.
about 80% freeware and 20% Payware is what I've got.
now if I can just make Video's of all them, kinda a Video history Vault, I'm workin on it, but its a process, and time consuming.
