What Flight Data Does a Custom Propeller Manufacturer Need?
A custom propeller manufacturer needs accurate flight, aircraft, motor, and operating data to design a propeller that produces the required thrust efficiently and safely. For Rayi, this information supports blade geometry, diameter, pitch, airfoil selection, material choice, balancing, and validation. Providing complete data helps a custom drone pr

Why Mission Profiles Matter in Custom Propeller Design
A drone can have a powerful motor, a high-capacity battery, and an advanced flight controller yet still underperform if its propeller is designed without a clear mission profile. This is one of the most common causes of excessive vibration, poor endurance, unstable payload operation, and premature drivetrain wear. When a propeller is selected only
