| Blade shape- Streamlined variable cross-section | Blade shape- transverse section,equal width section |
| The blade section is from wide to narrow (304-186mm),from thick to thin (43mm-21mm).Adopts the equal chord length principle and relative linear velocity characteristics to ensure the balance pressure of the whole blade to achieve the tip,middle and roots air evenly including the middle. |
The blade length is equal with cross section ,blade width is 19CM.High air resistance is not conducive to pushing airflow, holes in the middle, high energy consumption. |

| Blade material- aviation aluminum sheet | Blade material-Low grade aluminum |
| Adopt NO.5052H32 1.5mm thickness aviation high grade density aluminum alloy original plate,with high strength and flexibility,bright and durable. |
Low grade aluminum mixed with recycled aluminum for secondary processing, low density, impurities, pores, low toughness and easy to break |
| Blade weight-light | Blade weight-heavy |
| Each blade 6.7KG,total weight for 5pcs 33.5KG.Smaller blades ,lighter weight, reducing the motor load and extend service life, low energy consumption. | Cross section width equal to the blades, Each blade 10KG,normal 6pcs or 8pcs.Heavy weight, large motor load, high energy consumption. |
| Blade and petiole -- full mortise and tenon connection | Blade weight-heavy |
| The convex petiole and concave buffer device are locked with bolts, each blade is riveted with buffer device by 16 rivets,forming the blade, buffer device and petiole as a whole, torque and shear less and less. | Cross section width equal to the blades, Each blade 10KG,normal 6pcs or 8pcs.Heavy weight, large motor load, high energy consumption. |
| Buffer device-Rubber mat | Buffer device-No |
| The rubber pad between mounting hole of buffer device and shaped inserts to achieve the flexible connection between petiole and chassis.Rubber mat absorb the most of vibration, improve the motor shaft work conditions, extend the life, more quieter | Vibration cannot be weakened, resulting petiole and blades loosen,heavy loading, high noise. |
| Wheel chassis-Integrated hub | Wheel chassis structure-die cast |
| Special-shaped mounting hole and inserts locked each other to prevent the blade from swinging | Gravity die-casting aluminum wheel chassis or separated wheel hub, low strength, poor fatigue resistance. |
