<DIV>these bearings should last at least 300 flights, add 2 cups of reg
gas to a gal of your preferred model fuel - you will notice no diff in
performance but you will get necessary anti rust and cleansing additives that
are in the gas. </DIV>

<DIV>RE: OS 1.40 rear bearing rust - by Bax OS Factory Engine
Support<BR>~~~~~~~~~~~~~~<BR><BR>On a Pattern engine, being flown in a
Pattern airplane, 100 flights would be about normal for bearing wear.
A competitive Pattern flyer will need to change out the bearings 1-2 times
per flying season (depending upon how much practice time is
spent).<BR><BR>Corrosion is caused by model fuel. The alcohol in the
fuel absorbs water. Synthetic oils are slightly acidic and are not
corrosion preventers, they are lubricants. The two are not necessarily
the same. Some spent combustion products always work themselves into
the lower-end of the engine and they are slightly acidic. This
encourages corrosion by providing an electrolyte between the dissimilar
metals in the engine (aluminum and steel).<BR><BR>You need to run the engine
dry of fuel at the end of each flying session, and then flood the engine
with an after-run product. One of the hobby blends of after run oil,
Marvel Mystery Oil, automatic transmission fluid, non-graphite gun oil, a
good coating-type machine tool oil...all will work well.<BR><BR>If the fuel
has more than 25%-50% of the oil blend being castor oil, you'll also get
significant corrosion protection. Engines run on all-castor fuels
don't get much corrosion, but you do have to clean the engine to remove the
varnish buildup from the castor oil. It also will become gummy when it
sits for a long time. <BR><BR><BR>----------- End of Message
