Two items seem to be missing from the Materials list from the Builder's Manual, compared to the Steen Skybolt Bill-of-Materials.
Need to add the following to the builder's manual.
46'6" 7/8 x 0.049 Stab & Rudder Spars & Fuselage
8'3" 7/8 x 0.058 Rudder Pedals & Cable Bushings.
Order to ACS on its way.
