Quick post then got to run....
I chatted with Hueyracer by PM....it was more a language issue than technical....he is working in his second language.
I submitted an earlier post that seems to have gotten lost in the ether....which would have answered several questions posted by Birddog and others.
Since then...several folks have responded with explanations very similar to my lost post.
I will post again when I get back from introducing my almost foster daughter to the nice friendly Army Recruiter....she shows some interest in taking up helicopter flying although I would prefer to see her learning languages, the Law, or most anything else rather than helicoptering!
