The Halcyon 36 and 45 wings both have the expanding panels at the bottom of the wing on the OUTSIDE.
The 27 does not.
The Oxycheq 30 does not have the panels at all, and the 45 has them on the INSIDE, centered on the wing near the tank mounting area. As such the Oxycheq expands closer to the center of mass and buoyancy, and as a consequence the trim does not materially change.
It DOES with the Halcyon wings (speaking from ~100 dives worth of experience with the Halcyon Pioneer 36 here.)
