Hey guys. Well I just found out that I got accepted Officer Training School for the Air Force and a year of Pilot training after that. So it looks like my planes will be going into storage for awhile. I plan on removing all the engines from my planes to pack them up individually. My list of engines goes like this:

OS 91 Surpass
Saito 82
OS 55AX (2)
TT Pro 46 (2)
OS 20

What do I need to do to store these engines for a long wait while I go through school? Last time I let them sit a couple of them got rust on the inside and ended up costing me quite a few dollars in repairs (mainly bearings). Is there anything I need to do different for the two four strokes as opposed to the two strokes? What type of oil should I use internally to keep corrosion under control. They will probably be sitting in storage for about 1.5-2 years, just for a timeline. Any advice is greatly appreciated!! Thanks! [8D]
