I just started on the fuse, and have finished up the firewall, main center section and the f-705 rear spar/behind the seat section, and was looking forward to breezing through the rest of the formers. F-706 appears to be one twisted flimsy piece of metal. After toying ,fluting, seaming, cursing, etc,etc. it is laying sorta flat, but not real flat. The rest of the formers don't seem nearly as bad, and they have inside formed edges and a relieved area to stiffen them up. Just how fussy should I be with F-706, the 3 pc former??
