"Over the years Meyer has tinkered relentlessly with the program, producing some 140 new versions. His obsessiveness has kept him competitive. While several rival sims have withered in Microsoft's shade -- including Pro Pilot, Flight Unlimited and Fly -- Meyer has kept plugging along. But there are disadvantages to being a one-man show.

As stated in the article the simulator actually tries to model what's happening with the aircraft instead of using look-up tables based on full size aircraft, making it much more useful for modeling model... (small scale) aircraft.
