If your talking about the 1/2a combat hanging on the wall those are a design I did when my 2 boys were trying a little combat in the yard.
That did not last long, dog gone it! GIRLS!!!
To my memory the Combat Kitten had a shaped leading edge( hollowed) and a sheet balsa full depth spar.
Defiantly not a Lil' Satan.
The airplane in questions looks like a sit down with balsa, pencil, knife and glue and see what comes out!
I have much experience with this process!
