I decided to try making a Rahkshi kaita that could be made with three copies of the Stars Rahkshi set.
It turns out that, since the set contains 2 of the Light Bluish Gray Technic pin blocks, this was probably the best Stars set to try to make a kaita for, as the six connectors provide plenty of opportunity to connect the torsos together. The model even features rudimentary waist articulation:
Of course, this model leaves a bunch of parts unused, so I also did a render with more arms and weapons:
I think the armless version looks better overall, but I like the arms simply from a combination model point of view, since, with them, the combiner uses every single pieces from the three sets besides the 3 10L axles and the golden shields.
At the very least, I like to think I at least made a better combiner than Gaardus.
