I have built the Eduard 1/48 scale Mirage IIICJ in the Weekend Edition boxing (Mirage IIICJ Kit Review), and while it is a nice model out-of-the-box, it actually can be enhanced by using Eduard’s supplemental photoetch set. The single-fret set concentrates on the cockpit interior and adds just a handful of exterior details.
As you can see from the pictures, the cockpit looks much more realistic and has a great depth due to the sandwich of photoetch parts representing the instrument panel. While it might sound complicated, it is actually very simple to assemble. I only used a pair of tweezers and a #11 blade to position the parts. I used Future as my glue, which also provided a bit of a glass look to the dials.
