The DS-75-DIA HDT is based on the larger DS-94-DIA HDT and constructed in the same way with its outer diameter being reduced to 110mm. The smaller DS-75-DIA HDT can be used in models of the former 7.5cm³ ducted fan class.

Such models can be powerfully flown with motors of the 460g class and a power input of 2.9KW. The use of slightly smaller drive components and batteries results in an excellent price-performance ratio for our 110mm fan.

But our DS-75-DIA HDT even provides more potential: This fan can also handle power inputs of far more than 5KW thus being ideal for classy speed jets. Exhaust speeds of more than 96m/s provides best chances for new speed records.

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.
