<DIV><FONT face=Arial size=2>Around Sep 02, I rebuilt one of my OS EFIs - new
conrod, Shadel AAC piston/liner, and a stainless steel rear bearing w/ 2 rubber
seals. I use S&W fuel, 22% nitro, 17% synthetic, 2% castor and run dry
at the end of every flying session and then "burn" some Amsoil MP through the
engine (yes, the engine will run on the propellant in the Amsoil MP). A
fair bit of the Amsoil MP "oil" remains in the engine.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Approx 14 months and 700 flights later, the engine
is running as strong as when it was rebuilt. No bearing noise or
roughness. BTW - no brass fuel lines or clunk.</FONT></DIV>

<DIV><FONT face=Arial size=2>Good note, Ed! And timely reminder about
our old 2C .60 woes! Man, my OS 61RF would go through the bearings like
crazy!</FONT></DIV>
<DIV><FONT face=Arial size=2> Maybe Dave L. will chime in
about the double-seal bearings. I'd bet just about anything that they're
not "sealed", and that when removed, he's found plain ol' fuel oil leftovers
coating 'em. Maybe not.</FONT></DIV>

<DIV><FONT face=Arial size=2>Think about this. Have you ever seen
bearings rust in a tank with aluminum tubes and no clunk as in a Tetra
bladder tank setup ?? I've seen it, Dave Funk's OS 140RX in his Hydeaway
rusted the original bearing in very few
flights. </FONT></DIV></BLOCKQUOTE></BLOCKQUOTE></BODY></HTML>
