My initial thoughts

First, I don't have a pilot license. However, I have been doing some flying around in a PA-28 Arrow II and therefore have some feel of how it behaves.

I think this add-on is exquisite! The 3D model is absolutely perfect. The sounds are absolutely perfect. The systems are perfectly simulated. This is my first 3rd party aircraft add-on that I've bought so I can't compare it to the other ones, but it feels so... real!

These are the most significant differences between this model and what I experienced flying the Arrow II:

When turning "the ball" (slip indicator) stays dead in the center. In the real aircraft it took me a while to learn how to coordinate the turn so that I stayed level and kept the ball centered. In the simulator I just have to apply some aileron and elevator to get a perfectly coordinated turn. I checked my assistance settings to see if I had auto rudder or something enabled but I didn't so I think perhaps the flight model needs some tuning here?
Just before I reach rotate speed the aircraft gets super twitchy in yaw and it's almost impossible to keep it straight, especially with some cross wind. I remembered having to use the rudder pedals on take off to keep the Arrow II straight, but it wasn't anywhere near as twitchy. I have my rudder pedals mapped in FSUIPC with a 6 unit slope and once in the air it feels fine, but on the ground with some speed it feels very strange
The model starts rolling with idle throttle. Even though the Arrow II is a bit lighter I clearly remember having to apply some throttle to get it rolling.
This may have to do with my yoke or my sensitivity settings (have linear mapping on the axis), but the elevator authority feels a bit on the low side. In the Arrow II the elevator had a very direct response, but then again it's a lighter aircraft so that may be perfectly fine.

All in all it's a great add-on. There are some problems with the button mappings stated by others on the forum and FSUIPC identifies 4 instead of 3 flap detents, but I'm sure the developers will adress those issues in the near future.

If you are just a little bit interested in GA flying I strongly recommend buying this add-on!
