I store them nose up to keep the back bearing in the engine in the oil.
It does not makea big difference whether its nose up or down or level really. Just personal preference
Unfortunately, the back bearing in the engine is basically in the front part of the engine.
If you're going to fly the model sooner than later, it really doesn't matter which way. Back when I had lots of wall space, my models were alternated (and a couple were hung from the ceiling). Was there any difference? any problems? yes....
For models that didn't get flown for long periods of time, the nose down ones would gum the engines. Not badly, but it's worth mentioning. And the ones hung from the ceiling got more dust on 'em. Again, not a biggie.
I noticed the same thing. I have never lived in a state with a non flying season so it wasn't a big deal. I try to store mine like Jon has his. Room for me is a problem so it keeps me from having gtoo many planes.
