Honestly, I don't know... Are you in the US? If so, try Squadron Mail Order, as they seem to carry almost everything. Haven't seen a Fujimi catalogue for years, and I'm not sure what is currently being offered, but in the past those choppers came and went with the years. Heller's are I think more difficult to find, possibbly because of their fairly unpopular scale (Europe is still very much 1/72). E-Bay might be a good source. E-Bay France also if you are happy to do e-payments... Other than that, there are a numbe of other companies producing or having produced 1/48 copters, including Monogram (Mi-24), Trumpeter (HH-65),... Those should be easier to find.
