Construction Features

This hobby kit uses a no adhesive required assembly method. Parts are cut from the frame with specialised tools, then bent and connected according to the manual to form the three-dimensional structure. The connecting tabs are inserted into matching holes and folded into place to secure the build.

The process calls for precision, focus and patience, as the parts are delicate and small. For experienced hobbyists, that challenge is part of the appeal, making it a rewarding metal model kit to build step by step.

Model Steam build assessment

Work slowly when shaping the metal and check each tab orientation before folding it firmly. Repeated bending can weaken a small connection, so dry alignment matters more than speed. A tidy work area and suitable fine modelling pliers help with access to the narrow parts. No glue is required. The completed model is intended for display, with metallic colour detailing already present; a numerical scale is not stated.
