Question
Hi Mark,
I am building a Long E-Z kit plane and I am interested in researching the improvement of laminar flow over the last two thirds of the upper surface of the wing by evacuating the surface air. I can not find anything in print about this. Are you familure with this or can you direct me to where I might find info?
