STO X-AIR (X4 / X8) FPV Powerful Kit
Product No.:10021340 US$931.93

  • STO X-AIR is designed for better quality and experiences. With strengthen 30mm booms (thickness 1.2mm) and MIT pure carbon fiber (2/2.5mm), the structure is stable enough for loading a gown man (87KG). There are many large FPV drones and helicopters on market. However, the common problem is the weakness of structure, especially the hinge between power arm and central frame - the structure would be unstable due to design defects or low quality materials. Furthermore, the flight controller would be strongly affected and cause unstable flight at worst. 
  • Compared to other similar products, STO aluminum alloy hinges are much firmer and well-made. There is no gap between closed hinges. STO produces 30mm hinges especially for STO X-AIR.
  • The gimbal assembly location is compatible with DJIZ15. 
  • The fixed landing gear is included in X-AIR (X4 / X8) FPV Powerful Kit. X-AIR is compatible with STO Retractable Landing Gear for Large Multi-Copter[90021334] (optional)
  • The standard X-AIR Kit is quad-copter. With optional accessories, X-AIR can be upgraded to an X8 copter.
