Another RTU Overhaul

Back at the lab, the RTU had to be removed so that we could service it.


After draining the oil and opening the housing, it was clear that some of the bolts holding the stator had worked themselves loose again. This is a known issue, caused by a shortcoming in the design of the RTU.

For now, the only thing we can do is re-tighten the bolts and re-assemble the unit.
