  • Wrong airfoil
  • CG is too far forward
  • CG is too far backward
  • Motor thrust angle is wrong
  • Sweep angle is wrong
  • Winglets at wrong angle
  • No washout

That's why understanding the aerodynamic principles by reading and digesting the pages on flying wing design i linked to (written by a genuine professor in aerodynamics) is better than blindly accepting all the advice you hear in forums.
