Balsa Sheet .125" (1/8") Medium Density is ideal for constructing fuselages for Science Olympiad Catapault Launched Glider. If you are building a "Simple Simon" glider you should be able to get 16 - 20 planes out of each sheet. You will also need Balsa Sheet .03125" (1/32") to construct the fuselage (sold separately).
Medium density balsa is for use where weight and strength is equally important. Turner Toys also sells the same size sheets in Light Density Balsa. Balsa sheets are sold in 2 packs only. Save 5% when you buy two or more bundles.
