AMK’s 1/48 Mig-31 is a kit that, once you see one built, it grabs you. Phenomenal engineering of a large subject is a real show stopper. Even as well designed as the kit is, there is always some room for improvements. Aires to the rescue with a set of speed brakes and pistons as replacements.
Inside the package, you will find a left and right speed brake (they are handed so watch for location) and two pistons for support. There are no instructions as these are direct replacements for the kit parts.
Preparation consists of freeing the pistons from the casting block and webbing which is easily accomplished with a sharp knife. You can see that the Aires parts (also available from Quickboost as a standalone set) are cast finer especially in the piston parts. A small difference but noticeable.
