1:32 HIGHLY DETAILED EXHAUST NOZZLES SET AL-31FP ON SU-30SM

AL-31FP engine nozzles for the Su-30SM 1:32 from Temp Models

The set replaces the exhaust nozzles of both engines on a model of the Su-30SM in 1:32 scale. A resin 3D print can manage the thin petals, the external linkages and the internal detail, which an injection mold does not render faithfully because of the parting line. It is not a model of an aircraft but a replacement part for one.

The real subject

The AL-31FP is the version of the AL-31F turbofan with a vectoring nozzle added. The whole mouth of the nozzle swivels, which gives the aircraft extraordinary agility at low speeds and allows maneuvers an ordinary fighter cannot perform. The Su-30SM carries this engine in a pair and on a parked machine the nozzles tend to droop, each turned differently. That is exactly the detail by which a finished model is easily recognized.

Building and painting tips

First wash the 3D printed parts in warm water with a little dish soap, so that they are rid of the residue of printing resin. Cut the supports off with a sharp blade or a fine saw as close to the part as possible and sand the marks down with your airways protected. Resin does not bond with cement for polystyrene, so use cyanoacrylate glue. Lay a thin coat of primer on before painting, otherwise the paint holds poorly on a smooth print. The inside of the nozzles comes out best with metallic shades and a dark wash, which brings out the petals and the linkages.

Who the set is for

• The exhaust nozzles of the AL-31FP engines for a model of the Su-30SM in 1:32 scale
• An engine with a vectoring nozzle, which droops on the ground
• A resin 3D print with fine resolution
• An accessory set, not a model of an aircraft
• Calls for cyanoacrylate glue and a primer under the paint

The set is supplied unassembled and unpainted. Glue, paints and accessories are not included in the package, unless stated otherwise.
