EDF Ducted Fan Wemotec Mini Fan evo / HET 1W-30 4400Kv

Description

Modern high efficiency multi bladed fan unit. The fan unit comes completely mounted with a HET 1W30 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 4s setup for models weighting 1.8 - 2.4 kg.
Since current can reach up to 110 A readily installed, we recommend 2.600 mAh cells 30 C or better and a good 130 A speed controller. Throttle management is recommended to reach a good flying time.
Set comprises:

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.
