Can someone break down this animatronic wing build?

I’ve been looking at this wing build for some time trying to understand its mechanics and how to streamline it, the creator was generous enough to include a parts list yet I can’t seem to identify and find all of the parts, the motors are seem to be gear motors with some type of screw arm, the description listed in the parts list has made searching for most of the parts unsuccessful. What are the end pieces on the screw arms? Are these basically linear actuators? The video showing a demonstration of the wings make the motors appear to perform significantly faster movements than your typical linear actuator and I would assume they cost a bit less.

Would their be anyway to achieve the same degree of motion that these wings have while streamlining the design to something more simple and cost effective?
