Helicopter part taken from Cairo to Rabat (5)
I believe the answer is:
rotor
'helicopter part' is the definition.
('rotor' is part of 'helicopter')
'from cairo to rabat' is the wordplay.
'from' says the answer is hidden in the clue.
'ROTOR' is hidden within 'cairo to rabat'.
'taken' acts as a link.
(Other definitions for rotor that I've seen before include "Turning part of a mechanism" , "device for lifting a chopper" , "... and another" , "Turning component" , "Part of electric motor" .)
