Clecoed the spars and ribs together to form the frame work of the HS. Match drilled mounting holes and disassembled for de-burring. Fabricated the "cradle blocks" from the supplied plywood. Once again, i utilized the "CNC Router" to cut the jigs. Got everything set up and leveled on my work bench. Got the HS901 "Skin" out and used the soidering iron trick to remove the blue plastic along all the rivet lines.
