The F70 is a rare bird anywhere now, only came to Australia with Alliance when the acquire nearly all the Fokker left in Europe due to some deals they did where they gave shares in their company to Austrian Airlines in exchange for the Fokkers
the 10 Alliance have are here, choose a rego that might be easy to do
http://www.aussieairliners.org/Alliance/f70.htmI know RichW Decals on FB has them listed, but I think only an F100, depends on the rego though I guess.
As Wal has shown pretty simple, I painted the Yellow and blue, just used the name and rego's on a sheet that is no longer available.
I would have thought it would be simpler to cut down the Revell kit than muck about with the Welsh fuselage, but each to their own.
