Raid, my flying pal says there's a water-absorbing oil used commonly in compressor tools, which have problems with water residuals. I'll let you know what that is, but I'm going to start plunging high-quality, sythetic oil into my 4 strokes' crank breather after every run, and AFTER I run them dry of nitro. Also, if you look at that previous pic, you'll note I have disconnected the pressure and fuel lines--and connected THEM with a plastic tube which fits, saving whatever fuel is in the tank and DISconnecting it from the engine's carb. That oughta work, too, instead of pumping OUT the unused fuel every day.

I ALSO heard it's good to hang planes upside down, so whatever "oil" is in ther (including castor) will settle on the bearings. I have NO idea if that's a good idea or not, but where are engines cost more than $250 a pop, we ought to find out, hm?

Later.
