 Thrust 8.85kg 
 Controller >=160A / 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 PRO EDF Unit


The new carbon-120 JETFAN-120 PRO has been developed by Ejets for even more thrust with the same input power and better suction even with small and poor inlets. Ejets even achieve a weight reduction of 88 grams, and thus a total weight of 246 grams without heat sink, and 767 grams with mounted HET-800-73-590 KV engine! The basic design has been tuned to 50mm engines that are airborne with your full surface and bring up to 10 kilos of thrust under test bench conditions at 14s. The customers' requirement for a little more "audible punch and turbine noise" is achieved by more blades and lowering of the speed. Thus, we have again a distinctive sound, and could suppress the unpleasant high frequencies.

JETFAN ducted fans are already balanced.
