Did the initial build up of the HS. Man this thing is big!!! Didn't get many pictures. Fitted the HS 704 & 705 ribs. I don't really like the flange hole location and edge distance I have at the 705 and back of the front spar... I may add a couple rivets and a doubler to reinforce that area. Match dilled everything.... Now the fun begins. Hole deburr, prep & prime...
