In Rule (92).A, there is a general statement that you can use Tetrix Components. There appears to be no limitation, and they have a 180 deg. and continuous rotation servo in the list of Tetrix components, along with a servo controller. It would seem to me those are allowable within the aforementioned constraints. Please correct me if, and why I am off base.
In addition, I commented on the Hostbot servos as I am sure some teams would be looking at this thread that want additional servo information.
