GeminiJets JSX ATR 42-600 GJJSX2404: N400JX 1:400 Guide

GeminiJets item GJJSX2404 represents JSX ATR 42-600 registration N400JX in the carrier’s white-and-red livery at 1:400 scale. The finished regional-airliner model uses diecast metal construction, pad-printed markings, permanently extended landing gear and twin turboprop detail. A display stand is not included.

This is the compact 1:400 release, not the larger GeminiJets G2JSX1506 model at 1:200. Match manufacturer item GJJSX2404, registration N400JX, the ATR 42-600 body, JSX livery and barcode 763116424046. Three exact Muncle Mikes gallery images show the aircraft and package.

Why the JSX ATR 42-600 matters

JSX built its public-charter network around a premium, simplified travel experience using smaller terminals and regional aircraft. In 2025, the carrier announced plans to add ATR 42-600 turboprops so it could reach more underserved airports while retaining a 30-seat premium cabin.

ATR and JSX marked the start of the type’s public-charter operations in early 2026 after service began in December on the Santa Monica–Las Vegas route. JSX planned four ATR 42-600s in early 2026, each configured with 30 premium seats. GJJSX2404 captures that fleet transition in miniature through registration N400JX.

The model does not reproduce a working passenger cabin or certify the current route assignment of the full-size aircraft. Its exact product identity is the external aircraft, registration, livery and 1:400 format.

How to confirm the exact GJJSX2404 release

1. Read the item number. The package should identify GJJSX2404.
2. Verify the type. The aircraft is the shorter ATR 42-600, not the larger ATR 72-600.
3. Match the registration. N400JX should appear on the model and package.
4. Check the operator. The livery should carry JSX branding.
5. Confirm the scale. This release is 1:400.
6. Inspect the landing gear. The gear is fixed in the extended position.
7. Check the package contents. A display stand is not included.
8. Compare all three images. Review the fuselage striping, tail, registration, propellers, gear and box.

ATR 42-600 versus ATR 72-600

The ATR 42 and ATR 72 share a family resemblance, but they are not interchangeable subjects. The ATR 42-600 has a shorter fuselage and smaller overall footprint than the ATR 72-600. At 1:400 scale, the difference can be easy to underestimate in a wide product photograph.

Use the aircraft type printed on the package and the registration rather than relying only on the red-and-white JSX livery. A future JSX ATR 72 model would require its own product page, dimensions and article.

The 1:400 footprint

Exact-item listings place GJJSX2404 at approximately 2.23 to 2.25 inches long with a wingspan of roughly 2.42 to 2.5 inches. That compact footprint makes it practical for a regional-airport scene where several commuter aircraft need to share an apron.

The landing gear, propellers and wing tips extend beyond the main fuselage and need additional clearance. Measure the usable space between terminal structures, service vehicles and neighboring aircraft rather than using the fuselage length alone.

• Leave room beyond both wing tips.
• Keep service vehicles outside the propeller arcs.
• Do not place a jet bridge against the forward fuselage unless the scene is intentionally stylized.
• Leave tail clearance near terminal walls.
• Lift the model when repositioning it instead of sliding it across the apron.

Protecting the twin propellers

The six-blade turboprop assemblies are among the most delicate visual features on the model. They identify the ATR silhouette and can be damaged by a sleeve, cleaning cloth or nearby accessory.

• Do not lift the aircraft by a propeller or engine nacelle.
• Do not force the blades to rotate.
• Keep fingers away from the blade tips.
• Use a fine, soft brush for dust.
• Lower the model vertically into its inner tray.
• Leave open space around both engines in a diorama.

If one propeller appears loose or misaligned on arrival, photograph the condition before attempting any adjustment.

Fixed landing gear

GJJSX2404 uses permanently extended landing gear. There are no alternate retracted-gear parts identified for this release, and the wheels are not intended to fold into the fuselage.

Lift beneath the fuselage, set all gear points down together and avoid pressing on the nose gear while positioning the aircraft. Fixed gear makes the model ready for a parked-airport scene, but the small struts remain vulnerable to sideways pressure.

• Use a level display surface.
• Do not bend a strut to correct an angle.
• Keep the nose gear clear of raised pavement seams.
• Return the aircraft to the fitted package for transport.

No display stand is included

The normal presentation for this release is landing gear down on a shelf, apron or 1:400 airport base. Exact-item records state that a stand is not included.

A missing stand is therefore not a packaging error. GeminiJets-compatible stands can be purchased separately, but the fit must be verified before use. Do not drill the fuselage or force a generic peg into an unconfirmed mounting point.

Reading the JSX livery

The white fuselage and red graphic treatment give the model a clean, modern regional-airline identity. Registration N400JX, cabin windows, cockpit glazing, tail markings and red striping should be read together as the exact release evidence.

Pad printing places the markings directly on the finished model. Avoid alcohol, adhesive remover and abrasive polish. Use neutral light so the white fuselage remains distinct from the background while the red graphics stay saturated.

• Handle the model beneath the fuselage.
• Keep fingers off the registration and tail graphics.
• Use a pale gray or blue-gray display base rather than pure white.
• Avoid prolonged direct sunlight.
• Photograph both sides when the model arrives.

No opening doors or cabin interior are promised

Printed passenger doors, cargo outlines and panel seams are scale details. The doors, cockpit and baggage compartments are fixed. Do not insert a blade or fingernail into a seam.

JSX’s full-size ATR 42-600 uses a premium 30-seat cabin, but the 1:400 miniature is designed to communicate the external aircraft and livery. It does not contain a usable passenger interior, movable stairs or working lights.

Building a JSX regional-airport scene

N400JX fits naturally in a small-terminal or private-terminal display. JSX’s operating model emphasizes quick boarding and access to smaller airports, so the aircraft can be shown at a compact stand rather than surrounded by widebody ground equipment.

• Use low-profile passenger stairs or a simple boarding zone.
• Keep carts and vehicles clear of the propellers.
• Use a small gate or registration placard.
• Pair the ATR with JSX Embraer regional jets only when the scale matches.
• Leave open pavement around the wings to preserve the turboprop silhouette.

A restrained scene is more believable than crowding the aircraft with oversized accessories. Check every accessory’s scale and height before placing it near the propeller blades.

GJJSX2404 versus the 1:200 G2JSX1506

GeminiJets also produced JSX ATR 42-600 N400JX at 1:200 under item G2JSX1506. The two models depict the same registration but serve different display needs.

• GJJSX2404: 1:400, compact airport-layout scale, fixed gear, no included stand.
• G2JSX1506: 1:200, larger shelf-display scale with its own feature and accessory record.

This article owns the exact intent for GJJSX2404. The separate GeminiJets G2JSX1506 1:200 guide covers the larger release. The GeminiJets JSX model and scale comparison helps collectors choose between JSX aircraft and display formats without replacing either exact-product page.

Boxed display versus loose display

Boxed display

The factory box protects the propellers, landing gear, wing tips and tail while preserving the item number. Store it away from moisture and direct sunlight.

Loose display

A loose display makes the compact ATR proportions and JSX graphics easier to see. Use a covered case or airport scene to reduce dust, and retain the inner tray for transport.

Arrival checklist

1. Confirm manufacturer item GJJSX2404.
2. Match barcode 763116424046.
3. Verify ATR 42-600, JSX, registration N400JX and 1:400 scale.
4. Compare the white-and-red livery with all three Muncle Mikes images.
5. Inspect the cockpit windows, cabin windows, tail and registration printing.
6. Check both propellers and engine nacelles.
7. Inspect every fixed landing-gear point for alignment.
8. Confirm that no display stand is expected in the box.
9. Do not force doors, wheels or propellers.
10. Photograph both sides, top, underside, package and barcode.

Who should choose this release

GeminiJets GJJSX2404 is a strong fit for JSX collectors, modern U.S. regional-airline displays, ATR turboprop lineups, registration-focused aviation collections and compact 1:400 airport layouts.
