Aviatik, 'the new high-end magazine for aviation history'. The first issue's cover story is a feature on the Sänger spaceplane.
The publisher, Uwe W. Jack put out a small-format magazine under the same title back in the late 80s or early 90s which ran for about five issues (or that's as many as I got). From memory, its emphasis then was on projects, unusual prototypes etc.
(Credit where it's due, this new publication was flagged up over on
