A balsa wood sheet cut with the annular rings running through the thickness of the sheet is known as C-grain. A C-Grain sheet will be very rigid edge to edge and cannot be bent without splitting.
But when used properly, it helps to build the lightest strongest models. Most warp resistant type.
DO: Use for sheet balsa wings and tails, flat fuselage sides, wing ribs, formers, trailing edges. Best type for HL glider wings and tails.
DON'T: Use for curved planking, rounded fuselages, round tubes, HL glider fuselage, or wing spars.
