Mini Fan 480“ has been designed to accept the wide range of 29 mm motors, although it will gladly accept the SPEED 400
types as well.
The glass reinforced five bladed rotor comes in one piece, which makes assembling of the unit quite easy.
With a standard SPEED 480 race motor on eight cells one can achieve thrust figures in excess of 400 grams.
With the Plettenberg 200-20-6 or similar, thrust figures of 600 g and more are easily achievable, and with brushless motors
from Aveox, Hacker, Kontronik and Lehner thrust figures up to 10 N have been measured.

The standard for 90 mm ducted fans! Our Midi Fan follows the same design philosophy, that made the Mini Fan 480 a world
wide success already. It replaces both, Eco Fan II (EJT 540 unit) and Eco Fan pro (EJT cobalt unit). The new Midi Fan
stands for:
- maximum static thrust
- high efficiency at all speeds
- optimised sucking capability even in extreme ductings
The fan can be driven by a simple 540 can motor on seven cells, or by brushless motors running on more than 20 cells.
Depending on the motor used, static thrust in excess of 700 grams can be achieved at 200 W input only, but the fan can be
run on up to 1000 W input delivering 20 N of thrust and more.
The fan unit comes nearly ready to use. Just the rotor and motor need to be mounted.
Eco Fan II and Eco Fan-pro can easily be upgraded to the new standard by changing rotor and adaptor only. Costumors
reported, that the mangaged to upgrade fans of other manufacturers as well.

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.
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.
