As successor of the well-known DS-51-DIA 3-ph the DS-51-DIA HDT benefits from its predecessor's excellent aerodynamic design and also offers the perfect synthesis of high static and enormously high dynamic thrust. 

Cooling airflow has been optimized (as for all new HDT ducted fans) by an enlarged opening of the streamlined fairing. The optionally available Secure Fan Fix System enables exact installation within the fuselage.

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.

We also offer a "plug and fly" solution with the motor purchased from our product range ready-installed.
