The AIRES Mig-15bis engine replacement is a model kit in and of itself. It replaces the 3 part “engine” of the Eduard 1/72 kit. The AIRES kit is made up of 30 resin and 19 photo etch parts. The kit gives you a complete Klimov K-1 engine! The resin is fantastic with great detail and is very easy to remove from the pour plugs. The photo etch is very fine but has strength, so it doesn’t feel flimsy at all.
Build-wise this engine goes together very well and the instructions are pretty easy to follow. The only thing they don’t provide is a list of colors to paint the parts. There are many photos though on the web of Klimov K-1s, so it isn’t too hard to find the color scheme, but it would be nice if they told you what colors each part needed. I used Alclad aluminum, burnt iron, steel and, dark aluminum along with Model Master flat black.
