Look, don't get discouraged and please, feel free to ask all the newbie questions you want. Everyone has to start somewhere!
Quicksilvers explanation of buoyancy is even simpler than mine and I envy his simplicity. Also, I should have recognized that COG probably stands for Center of Gravity when discussing model building....Dolt! [

But hey, learning is fun too, and no one is expected to know everything. Thats why these forums are great!
As far as "malcontents" are concerned, do your self a favor and try to ignore them. This is not the first time I have seen those who feel they have cornered the "Fun" factor in the hobby business. (Your not wasting anyone's time.) Banner-ad sponsors, many fellow hobbyist and even myself (for what it is worth) welcome your participation. Who knows you may be the making of a champ someday! Or at least spend a lot of $$ trying...lol.
Hang in there, and not knowing is the first step toward learning!
