ClassicJetSims in partnership with Simultools released back in December 2009 the CF-104 Starfighter aircraft payware addon for X-plane 9 and X-plane 10.
The work done by Simultools includes model-polygon optimizations, UV creation, ambient occlusion and normal maps passes, paintkit generations, main liveries painting.
To date the CJS CF-104 is the most sophisticated starfighter simulation available and one of the finest military addon available on the market.
How to get it:
The CF-104 starfighter is currently not on sale, it is going to be brought back on sale once upgrade works are completed in order to make it compatible with the latest version of X-plane.
