This completely new fan is another design by Ulf Herder, utilizing CAD/CAM techniques. It has a 50 mm inner diameter and accepts motors up to 25 mm in diameter. The rotor is mounted on a prop adaptor which fits onto the motorshaft. Adaptors are available for 2.0, 2.3 and 3.17 mm motor shafts to fit all commonly available motors. Default supplied with a 2.3mm adapter, others can be purchased seperatly.
The fan unit was designed around the Graupner SPEED 300 motor, which gives about 200g of thrust on eight (small) cells.
As the rotor is glass reinforced, it is rigid enough to accept the power brushless motors, as delivered by Lehner, Halcher, Astro and other manufacturers. Because the rotor operates at extremely high rpm, we recommend the use of ball race motors like Multiplex Permax 280 BB or similar.
For the battery we recommend N-500AR cells with single engined models and CP 1300/1700 for use with twin engined models.
The fan unit comes without an intake lip, which therefor needs to be part of the model.
