Brengun has produced a photoetch improvement set for Eduard’s 1/144 scale MiG-15. There are parts to redo the cockpit interior, new landing gear doors, wing fences, a pitot, and antennas.
The project begins with the cockpit. The Eduard cockpit front is cut away, and the rest is thrown away. The PE kit contains the cockpit floor and sides, consoles, a seat and instrument panel. Also, you get seat belts. Wow. And there are two extra panels which are inserted on the cockpit sides after the fuselage is assembled.
I made a mistake here. I thought I should carve the plastic wing fences off and install the PE parts at this point in the assembly, before doing the landing gear. It turns out that the wing fences are much more susceptible to being knocked off than the gear doors or the landing gear. I had to put the surviving wing fences in the envelope and hold them after I knocked all of them off. The instructions are wise here, follow them.
