Inverted fuselage holder
You have many options on how to hold the fuselage while planking/sheeting the bottom.
Andy and Shane used a foam holder, which could be one made for modeling or cut from a cheap foam cooler.
I decided I wanted something with the sturdiness I had when sheeting the top of the fuselage, so I came up with the following. You may notice that this looks a little like the sliding battery tray.

Foam fuselage holder used for Oly prototype.
Hardwood clamp rails cut a little shallower than liteply. Being checked with scrap 1/4" ply used as the cross piece and connector between the 2 clamp rails.
Clamping rails need to clear the formers in the canopy area. Two bolts hold the cross piece between the two clamp rails.
Top view of the cross piece and rails clamped to the lower canopy frames.
Another piece of ¼ ply to fit between bolts. This will be glued to a vertical standoff. Wingnuts will allow removal of fuselage without disrupting the clamp rails.
Bottom view of the assembly. Don't get trapped by putting screws or bolts in from the top as the nuts won't be accessible when the bottom planking is completed.
¾" wood standoff glued down to old fuselage jig; 4.5 to 5" tall will allow the wing roots to clear the work table when upside down. The top is angled to match the canopy frame clamp angle when the fuselage is level.
The intermediate cross piece is glued to the standoff. The large wingnuts can be removed if necessary to release the fuselage without having to mess with the clamp rail setup.
The tail piece is made in a similar fashion, using the existing stab hold-down bolt.
