 HDT = High Dynamic ThrustThe 65mm fan for highest dynamic thrust 
The DS-26-DIA HDT is based on the DS-30-DIA HDT and is with 65mm diameter our smallest fan unit. Its aerodynamic characteristics are a perfect match for small and fast EDF jets. The rotor has only 3 blades which however have a big depth for an efficient airflow. 
Unlike other ducted fans of this diameter class its short rotor unit runs very smoothly and does not even overload a thin 3.17 mm shaft with undesirable resonance vibrations. Like his "big brothers" the DS-26-DIA HDT is also fully made of carbon fibre. 
All ducted fans of the DS-XX-DIA HDT series come fully assembled, fine-balanced and quality-checked, you simply have to install your motor and the system is ready to fly. Technical Data:- Diameter: 65mm
- Fan swept area: 26cm²

- Static thrust range: tbd
- Max. motor diameter: 29,3mm
- Speed range: 22.000 - 50.000U/min
- Power input: tbd
- Static efficiency: tbd
