Main Technical Specification:
1. External shape is designed in aerodynamics character and finished unit is compact, easy to carry away.
2. Key components are used by Aluminium material and internal S-shape structure design reliably ensure the vertical intergaration. Moreover, this can help ensure blades flexibility and distortion strength except its high strength.
3. Blades adopt composite material, which reduce the self-weight efficiently and is more delicate and better performance on balancing and safety improved a lot.
