Vortex 5 is available for electric system.
Simple and light weight design provides awesome flight performance and extreme 3D capability.

Vortex 5 adopted tail rotor belt drive system which make the helicopter more cheaper than shaft drive system and more easy for reparing.



Main Rotor head
With thrust bearing on main rotor head
Typical CCPM swashplate system which easy for pilot to control the helicopter on flying when you are operating 3D flying with fast speed.









Frame Part
Rigid carbon fiber frame design
Very easy for repairing when got unexpected crash!

Looking at the frame carefully. the size of servo mount tell you that standard servo are needed to drive directly.




Battery tray designed close to the rotor head makes it more easy to control gravity center of the helicopter.

Tail Rotor Head
Tail rotor head run with thrust bearing.
Rear tail servo mount been set on tail boom which makes it more convenient to adjust the linkage of tail servo, making tail drive rapidly
