HIGHLY DETAILED EXHAUST NOZZLES SET R15B-300 FOR MIG-25 RB/RBT 1/48

R15B-300 engine nozzles for the MiG-25RB, 1:48, from Temp Models

The set replaces the exhaust nozzles of both engines on a MiG-25 model in the RB and RBT versions, in 1:48 scale. The resin 3D print manages the thin petals of the variable nozzle and the internal detail that an injection mold cannot deliver because of the parting line. For the interceptor versions the manufacturer keeps a separate set.

The real subject

The R15B-300 is a turbojet with an afterburner, developed for the MiG-25 and its flights at great speeds and altitudes. The exhaust nozzle is variable and is made up of moving petals whose cross-section changes with the operating mode. The RB and RBT versions are the reconnaissance and bomber variants of the MiG-25, which differ from the interceptors in the nose and in their equipment. On machines in service the mouths of the nozzles tend to be strongly heat-discolored.

Building and painting tips

Wash the 3D-printed parts in warm soapy water first, to get rid of any print resin residue. Cut the print supports off with a sharp blade or a fine saw as close to the part as you can and sand the marks away with respiratory protection. Resin does not bond with polystyrene cement, so use cyanoacrylate glue. Apply a thin coat of primer before painting, otherwise the paint will not hold well on the smooth print. The inside of the nozzles comes alive with metallic shades and a dark wash that brings out the petals and the actuating rods.
