"In The Middle" follows "In The Beginning" to separate the project design phase from construction and assembly. For example above
you see the fuselage components. Blue are CNC milled Dow Styrofoamİ, white areas in fuselage drawing are CNC hot wired from Dow
Surfboard Foamİ a custom blended Styrofoam extruded polystyrene containing strands of Styrene.


The vertical fin components are composed of built-up and hot wired Dow HighLoad 60 Styrofoamİ. Wing composition is Dow
