 Caracteristics / LIPO12S
 Voltage45.5 v
 Current132.2 A
 Power5012 W
 Thrust8.55kg
 Controller >=150A / HV
Recommended Battery (measured with Hacker 5800mAh) >= 5000mAh 35C

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.
Note: this combo is provided assembled and balanced. You can also buy both the EDF unit and the motor separetly with us without the assembling and balancing service.


About the Ejets JETFAN 120 eco EDF Unit

The brand new impeller Jetfan-120 ECO was developed by EJETS for the 120mm EDF class. The basic design is towards average beam speed with very good static thrust. Since the jet models in this class are becoming ever larger and therefore heavier a powerful and fast start-up is very important. The mean jet velocity also allows large-scale and fast flying over the airspace. The requirement of customers for a little more "punch and audible turbine noise" We achieve this through more leaves and the lowering of the speed. Thus we again have a distinctive sound, and were able to suppress the unpleasant high frequencies. 

EJETS have also paid particular attention the 50mm internal rotor motors up to 52mm outer rotors can be installed. 

The weight of the Jetfan-120 ECO is around 333 gr, with achievable thrust of about 10 kilos at even normal currents it is the only ones in this class. JETFAN Ducted fans are already balanced.
