IIRC the one I downloaded for AFPD doesn't say "FlyingThingZ.com" on it?
Who do you think provided the CADS for the design. We also paid for the model to be developed for AFPD. Read the Readme.txt, read the plug for FlyingThingZ on the download area. We don't have to put the URL on the design since we are the ones who had it created and it's our model, we can do whatever we want with it!
So how would this apply to other models like an Extra or a Giles or a Shockflyer would I need to contact the respective copyright holders of each of those aircraft and ask permission?
It's the same. Lets see Knife Edge make a ShockFlyer without permission from Ikarus. You WON'T be seeing it happen. As far as Extra or Edge, they are monsters of a company who do not have to worry about having their models copied.
Thank god I am done contributing stuff their is just waaaaaay too much BS involved -not worth working for free anymore!
What's the BS? It's a matter of courtesy to the respective designer. I remember a certain person who copied a certain QQ scheme of yours and you about had a fit. What's the difference?
