The main problem I had hanging planes nose down is fuel leakage (you can never completely drain a tank). It works it way into the spinner and caused the spinner to spin off easily when starting the plane. If I hang a plane it is horizontaly or nose up.
I hang models nose down or store horizontally on a rack. Nose down is fine. Bearings accumulate some oil. That will go away with a flight or two. No problems here.
Ref. the fuel thing. On regular 2-line systems, I place a short piece of clear tubing (old nyrod, etc. ) spliced into the pressure line. When through flying pull the press. line apart with clear tube in tank side. Remove the feed line from throttle or filter and place on the tube. No fuel moves out of tank.
Three line system, close throttle to shutoff. Plug muff. pressure line. Fill line is plugged anyway. No spill on Mom's carpet, especially when carrying model from flying into basement. Learned that when I lived in yankee country and had that great basement.
