Mini 9 Grams Servo

Features

- 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
