First clarify FADEC. Old B3 not fADEC-single channel EECU, B3+ FADEC-twin channel EECU. EC120 has no EECU thus no FADEC. She carries a FCU as said before similiar to the AS350B2/Arriel 1 thus hydromechanical fuel control unit. Will she ever get the Arrius with EECU or newest with FADEC? Your guess is as good as the rest of ours. Personally I think she will be unbeatable with the new Arrius with FADEC but will it warrant the extra cost?????
