Hey Frank,hope all is well.
The Saturn wing panels in solid balsa 1.3 to 1.5oz each panel. If you cut panel for open bay wings and build in a custom lost foam wing jig,the panels weights can be reduced to under one oz each.
SV22,Impacts and pattern masters are a little heavier as they are thicker airfoils
The painted in the mold can increase by .5 oz per panel for the Saturn wing.
I built a model with a Saturn wing at 8.5 oz the impact fuse was 5oz the molded stab at 1.3 oz and I hated that model to light,no penetration. Lighter not always better. Model would not land in the wind 52oz 650 SI
Since I build my wings in a lost foam wing jig,I use all the ribs shown but are not required for strength.
The Saturn and SV wings in solid balsa can be built under 10 oz with belcrank and flaps.
The finishing process is greatly advanced do to the glass and epoxy outer surfaces. The painted in mold wings require little finish to complete.
One thing I learned is that the premolded balsa wings panels must have final sanding to get that perfect painted I finish.
