Modern high efficiency multi bladed fan unit.

This is an efficient 4s drive, which is used with small batteries (> 2.200 mAh), or where the MFE 2W20 is simply too strong.
It fits nicely into jets up to 1.4 kg AUW, or for example twin engined airliners up to 3 kg UAW.

The fan unit comes completely mounted with a HET 2W22 motor.
The unit is assembled and checked at factory, precision balanced and harmonically tuned.
