Well well well. Welly welly well. At long last, a solution to the tunnles problem. It's not quite as neat and compact as it could've been, but it can still be if my parts guy ever tracks down those 2 inch diameter connectors. Until then, this solution...is acceptable. Also, HamCopter is completed. Test flight without hamster to commence imminently, followed by a manned (hamstered?) flight. The big aquarium is also drained and cleaned out, although I have some decisions to make before I can commit to moving it over here.
