Completed the main spars by attaching the tie-downs and aileron bellcrank brackets. Tapped the tie-downs successfully as opposed to my first attempt on the tailcone tie-down. Used a lubricant given to me by a fellow builder which helped.
The next step in the plans calls for finishing up the main wing ribs, skins, tanks and leading edges. I am going to skip ahead instead and do the ailerons and flaps. That way I will be able to have table space to do them without the main wings taking up all my precious space.
