Just finished this one for the Great Patriot War GB, and build thread can be found here:

This ICM 1/72 kit was built straight from the box, but did add a Quickboost control stick (from the I-153 set), along with brass rods for some details, and some light bombs cobbled from another kit.
This early 1930's fighter was pressed back into service to replace losses suffered during the opening stages of Operation Barbarossa. While factories geared up to produce modern equipment, the I-5 would be employed mainly in the ground strike role.
