The mold-building process has begun on the horizontal tailplane.
This is the first of the “flying” aerodynamic parts to be started. It is proceeding in exactly the same way as the fuselage. First we cut a foam block with the CNC machine, then sand and paint it to make a plug. The mold is laid up on the plug, using high-temperature carbon fibre and resin. The actual parts will be laid up in the mold with lightweight pre-preg carbon fibre cloth.
