From Esprit Tech:
New Backpack XS2 is the stylish choice for a lightweight setup. For low wind conditions or indoor flying with a larger wing, combine the Backpack XS2 with a Power 1.1 wing or Hybrid 1.8 wing and a smaller power setup. For hardcore thrills, combine it with a 900-1000W power system and full size servos for an insane power to weight ratio and unbelievable aerobatic flight. Backpack XS2 features an all composite structure with stylish red plates and an anti-torque prop ring like the one developed for the Backpack M2.
Virtually perfect, extremely elegant combination of modern design and technology. Two color Carbon Fiber Frame, Propeller Ring, Two Servos with Control Horns and Installation Hardware included.
