You manipulate the blades where they attach to the hub, manually pulling the locking pins on two of them and folding them back along either side of the third. “And this is the system we devised so the pegasus can still gesture and communicate normally. These two folded blades can be positioned at any point along this range of travel, and the entire assembly can still rotate at the hub. Along with each blade’s ability to tilt, this means these three blades can replicate the behavior of a pegasi’s first three primaries on each wing, which Twilight told me is the core of their wing body language.”
