Part of whats happening is guy's have flown RF prior to the new RF physics, and are comparing it to Phoenix.
I started with RF Basic, and looking back it was more like a video game. But too judge the two sims you HAVE to fly RF6.5 to judge it properly. It is nothing like the previous versions.
I prefer Phoenix for just screwing around. Much better choice of Heli's, and I really like the ability to adjust my own transmitter. For a more realistic flight experience I fly RF6.5 It just feels more real to me.
Just my opinion.
