Hi Scott,
Uniflow is what I want to use. I have used bladders and wedge type and rectangular uniflo types and clunk types but I never used or build one of the "coffin" shaped type I see on good year racers. I don't fully understand how they are set up and what makes them work. Similar to the other types but not 100% sure.
pictures and drawings always help in the understanding, pictures in magazines and on the net don't answer my questions and there is no one around where I fly that can answer the question.
cheers, Graham
