After a lot of testing and experimentation, we’ve come to the conclusion that we either have to make the tail a lot shorter than we want to, or we need to add a support in the middle. We’re going with adding a support and then swapping springs out for door hinges on the portion of the tail before the support. The end segments of the tail should still be more fluid and floppy, like a cat’s twitching tail, and the part closer to the body will be more stable. Here we’ve added some thickness to the tail pieces to hold the hinges. These will get cut out to work visually with the cut-outs in the tail, but we wanted a successful test on it holding the weight first.
