● Newly designed wider main blade grips that increase the overall main blade disc diameter, resulting in dramatically increased stability and agility.
● Thicker main blade grip arms to increase durability and crash survivability.
● Expanded flybar supporting point design on control cage, increasing the rigidity of fly bar, resulting in improved flight stability.
● High precision bearing mixing arms for smooth and precise operations.
● Newly designed servo screw retainer to simplify servo installation process.
● Newly designed frame structure blocks and motor mount to simplify assembly, yet dramatically increase the overall frame rigidity, resulting in improved 3D performance.
● Improved battery mount for increased battery mounting rigidity, eliminating flight instability caused by movement of battery.
● Improved gyro mounting platform to avoid degrading locking performance as result of tail boom vibration.
● Tail boom support rods have been lengthened to suppress tail boom vibrations; integrated ends design improves durability and crash survivability.
● Tail control arm base is integrated with tail gearbox to improve control precision, and simplify maintenance.
● Newly designed high rigidity anti-rotation guide for improved operation precision.
