Absolutely. First of all we are happy to supply a pattern with your tail so you can chose your own coverings for it.
Also, if you want to "bulk" the tail up - by adding padding, to create different looks, that is also possible. The servos are reasonably powerful, and can move more weight than they are currently moving. So within reason, it should be easy to achieve that shape and keep the natural movement. We will be posting some video shortly of slower movements, so you can see the smooth action.
Shortening or lengthening the Tail is also possible - let us know if you need a slightly shorter Naked Tail and we will supply it. Longer Tails can be made to order for a (very) small additional pledge.
With a little imagination, we believe that almost any kind of Tail can be made - from rodents to dinosaurs!
