Flight-tested STL design package engineered for repeatable printability, modular structure, and real-world performance. Includes all print files, hardware reference, assembly guidance, electronics fitment list, and baseline print settings.
Compact 3.5" multirotor airframe purpose-designed for interior reconnaissance, confined-space navigation, and pilot training. Set up for analog FPV with a 19×19mm camera and built around durable PA612-CF nylon — ships ready to install electronics.
Platform-specific structural replacement arms. Validated fitment, same print settings as the original frame. Back in the air fast.
Field-replacement structural components for the Picket-7 ISR platform. Available at launch.
Platform-specific replacement components for the QR-31. Available alongside full platform release.
Compact 19×19mm analog FPV camera mount. Designed for the D-71 — compatible with most standard analog cameras.
Extended GPS arm for the D-71 platform. Optimized placement for clean magnetometer readings away from power electronics.
Purpose-built VTX mounting solution for the D-71. ASA material for heat resistance near the transmitter.
Complete hardware references, print settings, component specs, and step-by-step assembly logic. 26 pages.
Next-generation tactical multirotor. PA612-CF construction, ISR-ready, field-serviceable.
