The DS-30-DIA HDT is the successor of the very successful DS-30-DIA 3-ph and has the same "aerodynamic genes" as its predecessor. It converts the shaft power of the motor very efficiently thus providing very high thrust in the whole speed range. Once again the all-molded DS-30-DIA HDT with its high efficiency and improved cooling system sets the benchmark in the 69 mm ducted fan class.  

A special feature of this fan is the short and ultra-lightweight carbon-aluminium diagonal-rotor unit running resonance- and vibrationfree. The smooth performance of this rotor enables us to build this ducted fan with a very low tip clearance, thus increasing the total efficiency even more.

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.
