1:48 B-24 Liberator - propellers (2 types), engines & cowlings (closed engine bays) (4 pcs) (3D Printed) for HobbyBoss

Propellers, engines and cowlings for the B-24 Liberator, 1:48 scale

This is an add-on set, not a model of an aircraft. It holds four engine units with closed engine bays and two types of propeller, from which the modeler chooses according to the subject. On a four-engined bomber the cowlings are the most prominent feature along the whole outline of the wing, and this is exactly where injection molding runs into its limits: the leading edge of the cowling has to be thin, the finning of the radial engine fine and the propeller blades have to carry the correct airfoil, which twists along their length. 3D printing manages all of this at once.

The real subject

The Consolidated B-24 Liberator was an American four-engined bomber with a high-set wing of great slender aspect ratio. It was powered by four air-cooled radial engines in cylindrical cowlings, whose unusual oval shape is among the most easily recognized features of the type.

Usage tips

• Wash the parts in lukewarm soapy water; residue stays on the surface after printing.
• Cut the print supports off as close to the part as possible and sand the marks down; they have nothing to do with casting.
• Choose the type of propeller according to photographs of your particular subject; the set offers two versions.
• Bond with super glue, as printed resin does not react to cement for plastic.
• Dry-fit the cowlings on the wing and glue them only after checking the alignment.

Who it is for

The set is for modelers who are building the B-24 in a large scale and want engine nacelles that match the real thing. The work is not complicated; it only calls for patience in removing the supports and for exact seating of the four nacelles.

It is not a model of an aircraft. The base kit, paints and glue are not included in the package, unless stated otherwise.
