This particular setup is extremely light weight with moderate power.
It is typically used in relatively slow models like airliners.
Twin engined airliners may weigh in at up to 13 kg, and four engined airliners even up to 25 kg.
Modern high efficiency multi bladed fan unit.
The fan unit comes completely mounted with a HET 700-68-900 motor.
The unit is assembled and checked at factory, precision balanced and harmonically tuned.

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.

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.
Attention:
If not mounted within a proper ducting, the fan nees an intake ring. An intake ring is not part of this set.
