Hidden Side

LEGO® El Fuego's Stunt Plane

El Fuego's Stunt Plane belongs to the Hidden Side range, which pairs standard LEGO builds with an app-driven ghost-hunting story. With 303 pieces and three minifigures, the set centres on a stunt aircraft that works both as a standalone model and as part of the app's narrative, a dual role that sets it apart from conventional LEGO plane sets.

What can I build with it?

Description

A plane with two sides

Like many Hidden Side sets, this aircraft is built so parts of it can be reconfigured to swap between a normal look and a spookier alternate version, a switch that ties directly into the companion app. At 303 pieces the model stays quick to build, but its moving elements and transformation feature add more interaction than a static plane set typically offers. The parts list on this page identifies which elements handle the transformation and which are purely cosmetic detail.

Three minifigures, one story

Three minifigures give the set enough characters for a small scene built around stunt pilot El Fuego, whose name nods to the risky manoeuvres the plane is designed for. Dark blue and light bluish grey dominate the 139 unique parts, giving the aircraft a modern, technical look that stands apart from the brighter colours typical of classic LEGO City planes. Skipping the app entirely is no problem either, since the plane holds up fine as a regular building set on its own.

For fans of vehicles and mechanisms

Even without touching the Hidden Side app, the set works well as a vehicle build with more moving parts than its size would suggest, which makes it worth a look for anyone drawn to technical builds. The 139 unique parts point to a higher level of detail than the 303-piece count alone implies. The parts list makes it easy to spot the specialised mechanical pieces, several of which could suit other aircraft projects and give a sense of how the transformation mechanism works.

Building it and where it fits

At 303 pieces, the plane goes together quickly, making it a reasonable entry point into the Hidden Side range before committing to larger sets with more transformation features. Its colours and styling deliberately steer away from the friendlier tones of classic LEGO City vehicles, giving it a more distinct look within a wider collection. Anyone who owns several Hidden Side sets can use the parts list to check which mechanical elements repeat across the different models.
