Maybe I'm missing something, but where can I find more information about aerofly pro? I have tried both sites:
http://www.aerofly.de/
http://www.ikarus.net/

What models does it have?

What is the difference between aerofly and aerofly pro?

I can't seem to find an answer to these two questions in particular.

Thanks

The 21 standard models are depicted in the left-side bar links "screenshots 1" and "screenshots 2."

There are many more available for download, more all the time. I have 45 aircraft in my Aerofly Pro directory.

see:

I don't know the specific difference between the versions.

Regards.

Aerofly Pro is an improved version of its predecessor Aerofly. The Aerofly cannot be upgraded to Aerofly Pro. Go for the Aerofly Pro interface version which allows you to use your own Tx. What Tx are you using ?

I have a Hitec Flash 5. (computer radio)

If I use the GameCommander I assume I will lose the mixing, and exponential? Or is that available (via software) with GameCommander?

I don't speak German will that be a problem?

Use your computer radio features so that you'll get used to it and be able to explore it to the fullest. The software and manual are in English and German. The aerofly forum is also in English and German.

And there is software mixing in the program for the game commander. If you have the game commander and a transmitter, two can fly, split screen.

And it's all in English, French, German or Spanish, your choice.
