Aires has come out with a nice upgrade for the Trumpeter MiG-23 MF / ML kits with their Correct Tail Fin set. This set is specific to early MF / ML variants that did not have the leading edge extension (LEX) added to the front of the ventral fin. There are two parts in all, cast in a durable resin material. The Aires parts provide improved ventral fin detail especially for the pivot point that is exposed when the ventral fin is folded (landing gear extended) There are no supplied instructions; you simply swap out the kit provided plastic parts with the new Aires replacements. I’ve included photos of both the Trumpeter and the Aires ventral fin inserted in the Trumpeter fuselage.
Aires has molded the stabilizer and elevator perfectly in light tan resin with no apparent bubbles. The Aires stabilizer and elevator are supplied on a single resin sprue with thin resin attachments to the parts that should minimize any cleanup.
