RE: lift
hee hee yeah, its ALL true! The only "theory" i chuck out is the old school text book explanation of lift via Bernie's Nelly principle, you know, the air has to travel faster over the top to meet the air from the bottom at the trailing edge and the lower pressure in the faster moving air provides lift - bunkum as far as i can see! I think it been proved that it doesn't go faster over the top anyway, also it failes to explain flat plate wings and symmetrical airfoils. I did used to think it was to do with the air having to lose pressure/ get thinner as it expanded to fill the leeward side of max thickness - but then a theorist told me that thecentre of low pressure occurred above the max thickness zone, so that scuppered my simple view!
Having said that I understand that the CP moves back as airspeed increases. So i don't know what to believe now........... as long as it flies, eh!!!!!
