AircraftNut;
Thanks. I don't feel very welcome among all of these "experts".
Well then, ask yourself why you feel that way after just one post. A lot of people here have done a lot of work with a great deal of varied expertise and thought behind their contributions. They are no more special than anyone else except they have put in some time reading what others have said. You put the word "experts" in quotation marks. That is disrespectful to those here who, like yourself, have both a long list of qualifications and lots of experience to speak from. The contributors here who post the most useful and helpful information do their research first or they are reminded, sometimes politely even, that this is a serious discussion with some 3600 contributions which just may have touched upon the obvious items you posted. I hope this is of some help. The place is definitely worth the effort.
