Control Tower

The control tower was used to limit a drone's detection area to be within a thirty block radius centered around the tower, effectively giving it a "home" position. The control tower affects any drone with the control tower upgrade and a matching code.
With the overhaul of drone AI in R3, drones now have a built-in home position that rendered control towers obsolete. As such, the control tower was removed in R3.
This block can be returned to its crafting materials using the legacy wand.
