EDF Ducted Fan Wemotec Mini Fan evo / HET 1W-45

Modern high efficiency multi bladed fan unit. The fan unit comes completely mounted with a HET 1W45 motor. The unit is assembled and checked at factory, precision balanced and harmonically tuned.

This Pack, composed with the EDF unit, the motor and the assembling and balancing service, is precisely set, harmonically balanced and tested by us.

This is an extremely strong, yet affordable 5s or 6s setup.
Since current can reach up to 110 A readily installed, we recommend 3.000 mAh cells 30C or better and a good 100 to 150A speed controller. Throttle management is recommended to reach a good flying time.

  • 1 x Intake Lipo
  • 1 x HET 1w45

Readings:  We measure with a constant voltage of 3.7 V / cell. Current and thrust are measured with a small intake lip (r=6 mm) at 21° C, 50m asl and standard pressure. Depending on battery, controller and installation you may see higher or lower figures.The controller should be chosen 20% over rated due to the long lasting load.
LV = low voltage controller up to 6s, HV = high voltage controller above 6s.
Battery should be chosen about 15/ - 1/20 of the max current for 4-3 minutes WOT. 30-40 C is appropriate.
