The bearhawk is a high wing, 4 place aircraft with a tube and fabric
fuse, and metal wing.
The ridge runner (and 2 or 3 other very similiar planes built in the
same region) series are 1 or 2 place (tandem) high wingers, taildragger
or trike, just barely out of the ultralight class (some are done as
ultralights).

The T-18 doesn't fit my "mission" at all.
