On the SkyPup site the photos are groups by owner in the 'Kennels'
section. It will take a lot os searchign to find one with construction
details.

The show the spar and rib construction quite well.
The Sky Pup is made of foam, wood and fabric so it is a composite
aircraft. Most of the time when refering to composite aricraft the
speaker
means fiberglass, kevlar or carbon fiber.
Conceptually, those other materials can be substituted for the wood
in a SKyPup-like design, though ther result might not necessarily have
a better strenght to weight ratio. The wood in the SKy Pup is used
very
efficiently.
