This is a really nice flying plane and I am still flying it in Northern Australia and heading for Indonesia and Papua New Guinea! I don't know about other customers, but when I buy an aircraft add-on, and like it, I want to keep it in my PC Hanger for years! Regular upgrades and compatibility issues would be welcome. This particular add-on is not a "study-level" aircraft, but gives you a real chance to practice navigation using VOR, NDBs and there is a GPS for those so inclined. One thing that would really help sales on this plane and other older add-ons - make sure it will run on FSX Steam and other current and upcoming new simulators.
Happy Flying "UpYonder."
