OK, so i went and downloaded the freeware version, keep in mind i don´t have the payware one, BUT based on pics posted here:
The Icarus version have a more advanced virtual cockpit, freeware version, well, it stands as it is, but most definitely not MY cup of coffee, i´ll say Icarus nailed, big time.
Exteriors, well, the freeware version "feels" like it was intended for fans to make new paint schemes for it, while the Icarus version seems more "complete".Either way, both are great as they are, and i really think you have to be a Dragon Rapide fan in order to acquire the Icarus version, if you´re like me (not a rapide fan, for that matter) well, the free one will do, I for one, deleted it after a few hops, but just because is not my thing.
Best regards
