Airborne toy (4)
I believe the answer is:
kite
'airborne toy' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for kite that I've seen before include "Flying toy; a quality mark" , "aeroplane" , "Flying toy on a string" , "High as a - -" , "Raptor - flying toy" .)
