For the ultimate heavy bomber diorama, this mixed 3D-printed set allows you to display your 1/48 HobbyBoss B-24 undergoing flight line maintenance. The set includes four exquisite Pratt & Whitney R-1830 radial engines. Two nacelles feature closed cowlings for a standard operational look, while the other two feature completely open engine bays, exposing the complex rear accessory sections, engine mounts, and intricate plumbing. Also included are two styles of propellers to match different production blocks. It is an absolute show-stopper for detail-oriented modelers.
