I began designing aircraft in FS4 times almost 30 years ago and stopped after FS98. It became too much work for me alone then. I still work with aircraft.cfg, panel.cfg and Airport Design Editor. I like bush flying and airliner flying. Whenever I fly somewhere, I have to rework the airport there, either if it's a freeware or commercial product.
