Aires has come out with a nice upgrade for the Eduard Bf 108 series of kits with their horizontal control surfaces set. There are four parts in all, cast in a durable resin material. The Aires parts allow you to alter the position of the elevators and provide improved stabilizer to elevator detail. 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 Eduard and the Aires horizontal surfaces inserted in the Eduard fuselage.
Aires has molded the stabilizer and elevator perfectly in light grey 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.
