c...p,
I think you meant to say hydrolocking. Were did you hear about this?
Here is the definition from Wikipedia located at http://en.wikipedia.org/wiki/Hydrolock
In automotive terminology, a hydrolock (short for hydraulic lock) is the immobilization of an engine's pistons by a liquid (usually water, hence the prefix "hydro-")). Hydrolocking occurs when liquid fills a cylinder on the intake stroke and, due to the incompressibility of a liquid, makes the compression stroke impossible. This, in turn, prevents the entire engine from turning, and can cause significant engine damage if one attempts to forcibly turn over or start the engine.
I never heard of Saito having this problem, not to say it couldn't happen. Unless you plan on flying in the rain, I don't see how it could be a problem. Yes you have to adjust your carburetor on a high humidity day...less oxygen in the air. There again why would it only happen with the Saito and not an OS or any other 4 stroke?
I admit I am not an engine expert but I just don’t see it. I have a few e-mails out to some people I know who know engines so I will let you know. I suggest you research this a little more.
Good Luck,
Shubova
