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.

The CF-104 starfighter is going to be back on sale as soon as work is completed to make it compatible with the latest X-plane release 10.3
