Q250 4 Axis Quadcopter Frame Kit

Description

The NDK21 4 Axis Quadcopter Frame Kit from LOFTY AGROTECH is a mini-size drone frame designed with simplicity, strength, and performance in mind, making it ideal for drone hobbyists and DIY enthusiasts alike. Built from high-quality glass fiber, the main frame offers exceptional toughness while keeping the overall weight low. The arms, molded from ultra-durable Polyamide Nylon, come in visually distinct red and white colors and feature a unique downward angle design. This not only enhances flight stability but also promotes faster forward motion, thanks to the support ridges integrated into each arm. These ridges add structural strength, reducing the risk of breakage at motor mounts even during hard landings. With a lightweight construction and thick arms, the NDK21 ensures a balance between agility and mechanical durability. It is aerodynamically efficient and capable of maintaining stable hover at lower throttle levels. The entire take-off weight can be maintained around 500 grams, making it a perfect option for compact and responsive quadcopter builds. One of its standout features is the integrated PCB (Printed Circuit Board), which acts as a built-in Power Distribution Board, allowing you to directly solder ESCs to the frame. This eliminates the need for an additional PDB, making the build process cleaner and quicker. The frame also includes a camera mounting tab at the front of the bottom plate, suitable for FPV or action cameras. To streamline assembly, the frame uses pre-threaded brass sleeves for all bolts and requires only a single size hex wrench, thanks to its one-size bolt system—making both setup and disassembly quick and beginner-friendly. Whether you’re a newcomer or an experienced builder, the NDK21 is a smart choice for a sturdy, fast, and modular quadcopter build.
