EDF duct fan for 20mm diameter DC motor

pinshape

This 50mm EDF is built for small DC motors. I was surprised that a motor of this size could be powerful enough for flying models, but it's perfect for driving slower models such as cars and boats. Specifications: - The fan is a 9-blade design with a 45mm diameter. - It's suitable for 130/180 DC motors or similar motors with a 20mm diameter shaft. - The motor should be at least 20mm long to make disassembly easier. Assembly Hints: When working with different-sized motors, it can be tricky to insert them. To make the process easier, I recommend heating and softening the model using a hair dryer before inserting the motor. Always wear safety gear when handling these models, as high-speed blades are extremely sharp.
