try the version now, you only need to download the FlightGear-1.9.1... package.
I have renamed the original fgfs and replaced it with the wrapperscript that forwards all parameters to flightgear itself.
I'm having a problem showing the icon in the menu, let me know if this is a problem for others as well.
I included a -quite fancy- function - the terrasync system - please test it as well and let's see if we let it be included. There is a menuitem that start Flightgear with terrasync.
Terrasync downloads automatically the scenery from the web, whereever you are or are flying to. A fun way of using it is to find the airport code (ICAO code) for your local airport, and either edit the menu item or in a commandline type:
fgterrasync.sh --airport=EKCH --aircraft=777-200ER
this command will place you in Copenhagen airport, Denmark in a Boeing 777 - without you need to download scenery. First time you visit a new airport it is boneflat, let it download some terrain, and then restart the application (exit, a reload is not sufficient).
Arlanda in Sweden airport has the code ESSA by the way, and Heathrow in London has EGLL - find the codes with google/wikipedia. Great fun :-) I check with the developer of Kfreeflight that this function is enabled in the new version of kfreeflight:-)
Please do test on and send corrections if you find anything,
