I intend to use this Quickboost seat to replace the kit part in an Airfix A-4B.
The seat is molded in super nice bubble-free resin, with sharp, molded detail of the lap belts, shoulder harness, and oxygen hose. The primary and secondary ejection handles are molded separately and are located on the pour stub beneath the seat pan.
The stiffening corrugations on the sides of the seat are correctly portrayed as standing proud of the metal surface, whereas the kit part has them indented. This is a moot point, since when the seat’s installed they won’t be visible anyway.
When I placed the Quickboost seat into the Airfix cockpit tub, it was apparent that it was too tall---the canopy would never close. Compare the photo of the Airfix seat in the fuselage half on the left, with the Quickboost seat in the fuselage half on the right.
