Details

The MAD SPIRO AW 15x4.8" features an anhedral winglets design, offering stability and silence. Its unique downwarped shape reduces noise and inertia. Constructed with carbon fiber filament and high-performance materials, it provides a lightweight and strong design. New arrival.

The image highlights a unique winglet design that enhances flight efficiency for longer durations. The downward-facing winglets reduce vortex effects at the wingtip, minimizing losses, noise, and energy consumption. This improvement in airflow generates higher lift-to-drag forces, optimizing propeller performance and reducing vortex energy losses.

The image highlights the SPIRO AW 15x4.8" propeller, which features anhedral winglets to reduce blade tip vortex energy losses, vibrations, noise, and improve efficiency.

The SPIRO AW 15X4.8 Folding Propeller has dimensions of 381 x 122 mm and weighs 28.5 g. It is made of composite carbon fiber and engineering plastic, designed for folding. The working temperature range is -40°C to 65°C, with a storage humidity limit of <85%. Recommended thrust/RPM is 1-1.5 kg at 4500-6000 RPM, with a single thrust limitation of 3.5 kg. The propeller features a central hub with specific dimensions for installation.

The image provides test data for a motor, detailing its performance at various RPMs. Key metrics include thrust (gf), torque (N×m), output power (W), and efficiency (gf/W). The data shows increasing thrust and power with higher RPMs, but efficiency decreases as RPM increases. The contents section lists two folding propellers (SPIRO AW 15x4.8) and four hexagon socket head screws (M3×8).
