Fuel/Water, Bearing/Rust

[Jeff Hughes]

so why don't the 4stroke guys have problems? they are running much higher
nitro contents than the two stroke guys (typically)?

> I remember reading the Mintor instructions.  The instructions recommends
to run the engine with NO nitro if you are not planing to fly again for more
than a week.  Also, I remember many years ago when I flew in Venezuela with
NO nitro and we didn't have bearings problems.  Looks like we need to find
out if Nitro is causing the problems particularly in 2 C engines with large
pipes.  I think the nitro residues condense and form strong acid that
attacks the metals.
