Opinion changes of small flappers (6)
I believe the answer is:
swings
'opinion changes' is the definition.
'swings' can be an answer for 'changes' (swing is a kind of change). I'm unsure of the 'opinion' bit.
'small flappers' is the wordplay.
I cannot quite see how this works, but
'small' could be 's' (abbreviation - e.g. clothes size) and 's' is found in the answer.
The remaining letters 'wings' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'of' is the link.
Can you help me to learn more?
(Other definitions for swings that I've seen before include "Moves back and forth or from side to side while suspended" , "What you might lose on them, you could gain on the roundabouts" , "Moves in a curve" , "What you lose on these, you'll gain on the roundabouts" , "Pieces of playground equipment" .)
