In most cases a flight sim is your first or second investment into the R/C hobby world. Some people will buy a "parkflyer" have a bad experience and then get a sim to help them out. Others will go straight to the sim. G3 was my first flight sim and it modelled P-factor and engine torque quite well, if you gave a model full power and little to no correction it would veer off the runway. That no longer happens in G3.5 or G4. The P51 in G3 had a pronounced tip stall, that no longer exists in G3.5 or G4.

The "aircraft editor" is a great tool and you can "fix" most of the bad features that the stock models no longer dispay - except P-factor and engine torques. But, you have to know how that planes flies in real life to be able to do that. Beginners don't have that knowledge. And unfortunately, too many of the model creators that contribute those great models on the KE Swap pages don't have that knowledge either.

Getting a model to fly correctly doesn't seem to be a difficult issue for most sim producers. But getting that same model to handle correctly on the ground seems to be rather difficult. Yet, it wasn't so difficult just a few years ago when G3 was introduced to the market place. What changed? Or better question, who was influenced to change and why?

It's my belief that KnifeEdge was asked to change and GreatPlanes - they're customer - asked for the change in an effort to make RealFlight more of a sales tool for their airplanes.
