Judging by a pic on Sarna, i'd say it has a recognizable axe but not a rules-compliant one, no hand actuator...
Once I knew the Scarabus had a hatchet I went back and decided that it doesn't have a "hand actuator" in the sense of a manipulator, but it does have an extra swivel below the elbow, and the blade is in a slot, so there are ways to fine tune the blade position. In a person, the power comes from the hips and shoulder. Gross aim comes from the shoulder and elbow, and fine aim comes from the wrist/hand. The Scarabus takes the very logical step of skipping the traditional "hand," with its 15+ separate joints and FSM knows how many components, and bolting the blade to a modified "wrist." So, with a bit of abstraction and mental gymnastics, the Scarabus does
look rules compliant, at least if ****** my head and squint a little.
I can't make the Nightsky work, though. That blade is just bolted to the vanbrace. No two ways about it.
Interesting detail. Pity the upper body looks terrible.
No argument, although neither the hatchetman or axman is exactly the belle of the ball, either. Although the art in later versions manages to massage the proportions so both come out looking a bit better.
