Hotwired foam Flying wing - 45" ~~ 114.5 cms Airfoil : MH64 Span : 114 Root Cord : 30.5 Tip Cord : 23.5 Twist : -1.7 degrees This is hot wired out of expanded polystyrene. It done in the single template method,  with one end of the wire anchored Tips had -1.5 degrees of twist Below is one of the cores after the cutting . it has come out very good . the template is still fixed to the core   the core without the template. Note the cord line the  calculations are Pictures of the finished wing Motor - 2230 1780KV ESC- 30 amps..
