Made some more progress.

1. Decided to make the balsa block in front of the wing removeable. So I reinforced the wing hold down straps and put a tongue on the balsa block.

2. Installed all the stringers that give the fuselage it's rounder shape. I mitered the joint of the side stringers where the fuse angles to a narrower shape and don't like the protrusion, so I will sand them down to smooth out the transition from front to aft of the fuselage.

3. I also installed a solid block in the space under where the horizontal stab attached to the fuselage. This will make it a lot stronger.

4. Added the rear wingmount blocks. Still have to drill and tap the blocks.

5. I covered the horizontal stab with fabric.
