Someone on here mentioned a presentation by Loek Boermans at the
recent SSA conference, where he stated that modern, thin, laminar-flow
sections don't climb as well as they theoretically should in bumpy
gusty thermals. Apparently research into ways round that are ongoing,
but the Jonker brothers stumbled across an airfoil for the JS-1that
doesn't suffer from this by accident!

Maybe someone who attended could expand on what was said? It sounded
very interesting.
