The richest selection of deflected surfaces goes to quarter scale. 1:48 aircraft control surfaces are listed here as resin castings of flaps, ailerons and rudders, each made for the kit named on the set. Swapping the moulded-in parts for resin changes how a Spitfire or Bf 109 sits on the hardstanding, and the fine rib detail stands up to close photography.
Before ordering, confirm the set matches your kit from 1:48 aircraft model kits, because resin will not seat on another tooling. Cutting, sanding and seating are covered in the aircraft control surfaces overview. Have cyanoacrylate ready from the adhesives listing before you start.
