3D LABPRINT Nakajima Ki-43 Hayabusa

This fully 3D-printable RC model recreates a classic aircraft and is specifically designed to be affordable, easy to build, and stable, making it ideal for everyday flying. Numerous scale details, such as realistic airframe paneling, allow for highly authentic paint schemes. The model is optimized for PolyLight LW-PLA 1.0 active foaming filament, enabling even small printed aircraft to achieve weights comparable to traditional RC construction methods.

These are among the first fully printable airplane files created for home 3D printers that deliver flight performance comparable to—and in some cases better than—conventionally built models. Simply download the files and print the entire aircraft or individual replacement parts whenever needed, at the cost of filament alone.

Advanced 3D-printed structural reinforcement ensures excellent rigidity while maintaining a lightweight airframe and accurate airfoil geometry. This level of precision is only possible through additive manufacturing, offering a true next-generation approach to model aircraft design.

Assembly is straightforward and requires no specialized tools or hardware. Printed parts are glued together, simple pushrods are added, and standard RC components—brushless motor, ESC, servos, and radio—are installed. Comprehensive step-by-step PDF and video instructions are included. The finished model delivers efficient performance with flight times exceeding 15 minutes, smooth scale-like cruising, and a low stall speed that makes landings easy and predictable.
