Altitude Holding by Inertial Navigation
The flight controller F120 developed by RadioLink combines Kalman filtering technology and inertial navigation algorithm (gyro+accelerometer+barometer), allowing F121 flight with accuracy altitude hold even through narrow space or no matter how close to the surface (less than 10 centimeters height).
Easy from Zero to Hero
Education and Training
Altitude holding by inertial navigation and PID autotuned makes it easy from zero to hero.
The size is small and easy to carry makes pilots fully enjoyed even with small space indoor.

Thrown and Flight at Any Angle
F121 can be thrown and starts to fly at any angle. A fixed head without a compass means the head of F121 always remains the same direction if the rudder stick is not moved. Otherwise, it will change according to the rudder stick. Move with a simultaneous response, F121 makes every beginner flight like a master.
The propeller from GEMFAN takes full advantage of aerodynamics and repeatedly tested and modified. The propeller has designed based on its weight and the effects of thickness distribution on rotary inertia that make the propeller rotary balanced with small vibration and stable flight at Rate Mode.
Propeller Protection, Safer to Training
The rectangular half-bale snap-type propeller protection is adopted to protect the pilots from being hit. Meanwhile, the propeller protections are installed on the plate so that the collide will not make the motors crooked to affect the flight effect or break the motor line.
Flight with FPV
Experience a Different World
The advanced version of F121 is equipped with a 25mW image transmission system that integrates camera and OSD module*.
Connected with FPV displays or FPV goggles,
flight becomes amazingly easy and intuitive.
*the OSD module supports voltage, flight time, power real-time feedback
USB LiPo Battery Charger
Easy Energy Supply
The brand new designed LiPo battery charger CM120, especially for 1S LiPo battery, possesses the high precision as other professional chargers from RadioLink, guaranteeing safer charging and longer lifespan. 1S battery charged by CM120 ensures a flight time of six to eight minutes.
Three Flight Modes
Beginners can start from Altitude Hold Mode (Low-Speed) to Altitude Hold Mode (High-Speed) to the Stabilize Mode and easily achieved the advanced level as a drone master.
Entertaining and Educational
Always Well Engaged
The whole mini drone can be easily disassembled or assembled with the DIY ability and aircraft knowledge of RC fans well-exercised and learned. Drone beginners will enjoy the fun of flight and even of the more advanced parameters setup.
The “Eneopterinae” shell of F121 is full of childhood, a great gift for your son or daughter.
Easier for Drone Training
With the flight controller F121, which with PID Autotune, F110S V2 can automatically correct the flight angle, makes F121 easy to be controlled.
LED for Night Flight
F121 support the LED (green and blue) for night flight, it is easy to recognize the direction even flight at midnight.
