Flyer produced by master with Napoleon complex (9)
I believe the answer is:
monoplane
'flyer' is the definition.
(monoplane is a kind of aircraft)
'master with napoleon complex' is the wordplay.
'master' becomes 'M' (common abbreviation eg MA, Master of Art).
'with' means one lot of letters go next to another.
'complex' is an anagram indicator.
'napoleon' anagrammed gives 'onoplane'.
'm'+'onoplane'='MONOPLANE'
'produced by' is the link.
(Other definitions for monoplane that I've seen before include "One-winged aircraft" , "Single-winged aircraft" .)
