Generally speaking, it is better to get FlightGear for free and buy a good flight stick and/or a pedal. Therefore we have no responsibility for providing any support for such products. However, we have never received any donation or single penny on your payment for such paid product.
It's totally up to you for paying some amount of money for software and scenery that you can get for free. We have heard that there are some paid products that use FlightGear, and their web site or a starting box seems leading you to this site for either downloading the binary or support.
This is a download page for FlightGear Mac OS X, a free / open-source flight simulator. Important Notice from FlightGear developers
