Yes, as Ken suggested, glue it in. The most important part of this evolution is that you do not get glue either on the back side of the torque rod or inside the brass tube (if there is one) that guides the torque rod between the two halves.

Before you do anything, though, carefully inspect the two torque rods to make sure that they are both identical but opposite. One for the right side and one for the left side. The angles that the bends are critical. Any differences induce some differential in the ailerons and makes it a bit more difficult (not much more, but somwhat, and avoidable if set identically) to align the two halves after you are done.

Best of luck with this and let us know how it flys once you are finished.
