Since the stock planes are considered commercial software, it's most important to ask for permission from IPACS or Ikarus direct. They have contact info on both of their websites. In most cases they will say yes, they just want to know who you are, have your contact information and that your intentions are in the best interest of AFP or AFPD.

If you just want to post a skin for any plane commercial or not, you can of course. But not the original model. Just include a readme file that explains how to add the skin to the model. This is the safest way.

By the way Rick ... where is that Blackbird for AFPD you made a while back?
