Mainly for extra awesomeness lol. It's controlled by a 35kg servo so it does have a bit of power to help get itself free if other bots get stuck on it. All the joints are rubber mounted to it is designed to take impacts and keeps opponents away from the back of the machine which will house the rx and all the mechanism for the self righting arms. So it does serve a purpose however only a small one.

I do still have the original 0.6mm titanium tail which I was thinking of mounting to a base plate and attaching a servo to make it operational then selling.
