High flyer's current motors outside for all to see (6)
I believe the answer is:
icarus
'high flyer's' is the definition.
(Icarus flew too close to the sun in Greek myth)
'current motors outside for all to see' is the wordplay.
'current' becomes 'I' (symbol for electric current).
'motors' becomes 'cars' (I can't explain this - if you can you should give a lot more credence to this answer).
'outside' indicates putting letters inside (some letters go outside others).
'for all to see' becomes 'u' (short for Universal film certificate).
'cars' placed around 'u' is 'carus'.
'i'+'carus'='ICARUS'
Can you help me to learn more?
(Other definitions for icarus that I've seen before include "High-flying son of Daedalus" , "foolish high-flier" , "Flier with wax wings" , "Legendary Greek youth who flew too close to the sun and was killed" , "Excessively high flier" .)
