Plans page SNX-T05 was detailing the Horizontal Stabilizer skins. This was provided with the kit. Moved on to SNX-T04. Built four ribs (two for each side) SNX-T04-04 and SNX-T04-03. These were built form Z04-02 bent aluminum stock. These where cut to length, one end on each was cut to shape then bent down to provide a riveting flange. The other end was cut to shape and then bend 68 degrees to match the forward spar.
