Raghav,

It is perfectly legal to sell copies of flightgear, however I would advise
you not too. Flightgear is built entirely from the generosity of its users
and I'm sure they won't appreciate you taking their hard work for your own
personal gain. My suggestion: add your improvements to flightgear for free!
Please try to understand.

Thanks
