You are correct David, the only wood in the kit is the firewall and misc. hardwoods. You would have to furnish all the balsa needed to complete the airframe. There is a Gator products wing tube included in kit along with 2 sets of wing cores,1 set of stab cores and 1 rudder core. 1 rolled set of wing plans (full scale) and 1 set for the fuselage (scaled down)
