I've been noticed that the installer has an issue and misplaces the files in the FSX folders (it places the model files into the SimObject folder, but they should go into the SimObject/Airplanes subfolder). If you know how to install FSX files manually, you are probably able to fix this.... but I've fixed the bug and an updated installer is being uploaded right now... sorry for the inconvenience!!!!
For one, calling the project "The Real F-35" is not an idea of mine, and I will ask SimMarket to change it. I believe it is a reasonable simulation - but it is far from being as "real" as other addons.
The product has still some bugs - sorry for that - but I hope that the quality level is acceptable for most users as the price - if my calculations are right, this will be just enough to cover the development costs. Again, this is not a job for me, nor I do not want it to be - still, I hope the F-35 is "professional" enough for most users to enjoy flying it. Have fun!
