Toys that fly (5)
I believe the answer is:
kites
'toys that fly' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for kites that I've seen before include "aircraft" , "They're flown in the wind at the end of a string" , "Birds of prey - flying toys" , "Small hawks" , "Large hawks or flying toys" .)
