Stocks of Wemotec Fan units have finally arrived again
after a long break due to manufacturing problems.
The mini fans are now dynamically balanced at the factory to
7/1000th! This means no more having to balance the rotor yourself
and much smoother fan running straight out of the box.

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 motor shaft. Adaptors are available for 2.0, 2.3 and 3.17 mm motor shafts to fit all commonly available motors.
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 engine models and CP 1300/1700 for use with twin engine models.
The fan unit comes without an intake lip, which therefore needs to be part of the model.
