Product Features

1. Mechanical Elastic Propulsion: Powered by a simple, replaceable standard rubber band twisted along the central fuselage frame to drive a high-efficiency front propeller.
2. Optimized Flight Geometry: Engineered with slightly swept main wings, rear horizontal stabilizers, and vertical tracking fins to maximize glide time and maintain steady flight stability.
3. Ultra-Lightweight & Tough Frame: Features a minimalist structural central spine that keeps weight exceptionally low while ensuring the aircraft survives high-velocity landings.
4. 100% Support-Free FDM Printing: All components—the fuselage, main wings, propeller, and tail fins—are designed to print completely flat on standard build plates without wasting time or filament on structural supports.

Printing & Assembly Recommendations

1. Filament Choice:
2. Main Body, Wings, & Propeller: Standard PLA or lightweight PLA (LW-PLA). Keeping the print as light as possible is essential for optimal flight performance and longer air time.
3. Print Settings: * Print the wings and stabilizers with a single wall loop (perimeter) and a very low infill (or 0% infill with top/bottom layers) to keep the weight minimal.
4. Ensure your print bed is perfectly leveled for a smooth, aerodynamic finish on the wings.
5. Hardware Required (Not Included):
6. 1x High-elasticity standard rubber band (easily sourced from office supply or grocery stores).
7. A small piece of thin metal wire or a paperclip to fashion the front propeller shaft hook.
