An*excellent*book on the topic of making foam core wings is "Radio Control Foam Modelling" by David Thomas. *Shows all sorts of tips and*techniques, paperback. I don't think foam core wings will ever be as light as built up wings, with the possible exception of vacuum bagging carbon fiber cloth over foam, but that would be an expensive proposition. *Each method of building has it's advantages and*disadvantages. *
