This is the OXY Heli Oxy 3 Flybarless Electric Helicopter Kit, with an included Lynx Heli Stretch Kit and 285mm ZEAL Carbon Blades.

OXY Heli's Oxy 3 Flybarless Electric Helicopter Kit is the first helicopter in the Oxy Helicopter line. Developed by Lynx Heli engineers and designers, the Oxy 3 is a 250 electric flybarless machine that delivers performance qualities to suit both 3D and sport pilots alike.

With a simple, robust and lightweight design, the Oxy 3 flies like a much larger heli. Using micro size servos, a belt driven tail rotor, flybarless head and transmission that can handle RPM's up to 4500, the Oxy 3 can be setup mild or wild. The choice is yours. Plus, the 75mm battery tray can fit batteries from 3S to 6S, and an optional stretch kit will be available soon to accommodate 280mm blades (included in this kit). Additionally, specialty upgrades will be available to allow the use of either 3 or 4 blade heads, with a full length fuselage to customize the look of the machine.

Stretch Features:

  • Incredible larger feeling, increased visibility and flight precision
  • 25mm longer tail boom for increased tail authority
  • Optimized lightweight design
  • Lower head speed results in more stability and more visibility, perfect for practice and beginners
  • Higher head speed creates excellent agility and pops and super stable in the high speed flight
