Some echo the advice for a Spitfire (7)
I believe the answer is:
hothead
'a spitfire' is the definition.
(thesaurus)
'some echo the advice' is the wordplay.
'some' indicates the answer is hidden within the clue (some parts of the word are used).
'HOTHEAD' is hidden in the letters of 'echo the advice'.
'for' acts as a link.
(Other definitions for hothead that I've seen before include "An impetuous person with warm cranium" , "Daredevil" , "Tearaway" , "Headstrong type" , "Excitable person" .)
