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. Plans are being considered to overhaul this fine bird completely and bring it back on sale for the latest version of X-Plane.
