EXPERIMENTAL
Linux support is being provided as a Provisional Trial and as such you may experience bugs more often than other Operating Systems.
Gizmo64 products will should "work" on Linux now.
Built with Ubuntu 12.04 LTS 64bit
Gizmo64 and X-Aviation are separate entities.
A Linux plugin does NOT imply full commercial support.
Please read and understand the product information pages before making any purchase.
Users are expected to be patient and resourceful if experimenting with the Linux build of Gizmo64.
The next public release of Gizmo64 will include a Linux XPL plugin.
As SkyMaxx Pro is not a Gizmo only product (meaning it uses only small pieces of it), the answer would be "no" to Linux compatibility. Ben is simply providing folks the opportunity to use Gizmo in an unsupported form. As of this moment there are no intentions to support Linux on the X-Aviation commercial product line. You can purchase products at your own risk, but you'll need to ensure these would even potentially work with what Ben is providing you, and you should expect to not receive support should issues arise.
As a short list:
MU-2
Saab 340A
C400
DC-3
