I kinda wondered the same thing when I was looking for a sim... They were the only ones that had the E-Flite Blade 400 already modeled. Since I was getting a Blade 400 at the time, I figured it would be perfect! But unfortunately, they were out of stock on the cable/sim software bundle I needed for the DX6i transmitter, so I wound up getting Realflight G4 instead.

People say Phoenix is better, but as a newbie, I can't tell the difference. All I know is G4 was instrumental in my going from an initial crash-n-burn attempt to get off the ground to hovering and forward/reverse flight in 2 weeks. There were subtle differences from the sim compared to the "real world", but it was minimal.

Now, if someone would just model the Blade 400 in G4, I'd be a happy camper...
