Eduard has released a PE exterior and interior upgrade for their new 1/144 MiG-21bis. I’ve reviewed the kit separately.
The “Kit”
Inside the envelope, you get a 2 ½ by 3 inch PE fret, cockpit and canopy detail, decals, and the instruction sheet. There are enough parts on the PE to do one of the two MiGs in the kit, and some “extras” which could be used on the second aircraft, such as the two different sets of chocks or the tailpipe interior which doesn’t need to be installed if you’re using the exhaust cover.
