Free?? Do a search. Model Airplane News has three of them, all about 20 bucks each. All are marked as LD2, Beginner to intermediate. One of them has some foam though. The one I like is designed by Keith Sparks with a flat bottom wing and a 61 inch wing for two .25s. One is for 1/2A and the one with foam is for .15s to .25s.
