Chopper landing revolutionary in China (7)
I believe the answer is:
machete
'chopper' is the definition.
(blade for chopping things down)
'revolutionary in china' is the wordplay.
'revolutionary' becomes 'che' (Che Guevara the Marxist revolutionary).
'in' indicates putting letters inside.
'china' becomes 'mate' ('China plate' is rhyming slang for 'mate').
'che' placed inside 'mate' is 'MACHETE'.
'landing' acts as a link.
(Other definitions for machete that I've seen before include "Cheat me over broad heavy knife used in jungle" , "The mace (anag.)" , "Broad heavy knife common in Central America" , "Teach me with large jungle knife" , "Broad heavy knife used in S American jungles" .)
