I wanted to use the kit decals for Boris Safanov, but when I put them on the kit they would not lay down. I used the stars from the I-15 and I-153 to represent an aircraft from the 67th IAP.
The undersurfaces are AK Interactive Real Color RC310 AII Light Blue with RC311 A-18F on some of the metal panels. The wheel retraction cable is Wonder Wire.
The MGs and pitot tube are Albion Alloys .7mm brass tubing. The kit provides an engine, engine mount and some internal parts if you want to display it with panels off.
