We have just been to the Phoenix website (phoenix-sim.com)
We keep finding new models and flying field for free. This is really impressive.
We also own the realflight G3.5 but are a little dissapointed to find that they have introduced a whole new sim version 4, which has a totally different transmitter and no downloads are available in line with Phoenix.
As far as we have found, the real flight does offer other official models, but these are in the form of upgrade expansion packs with a fee.
Phoenix have done much the same as realfight in that they have improved on their graphics and use water to great effect. Their latest reflection are wonderful.!! A few screen shots below.
