Inertial navigation fixed high MINI night race through the golden lacewing F121 Pro

Altitude Holding by Inertial Navigation

The flight controller F121 Pro developed by RadioLink combines Kalman filtering technology and inertial navigation algorithm (gyro+accelerometer+barometer), allowing F121 Pro flight with accuracy altitude hold even through narrow space or no matter how close to the surface (even 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.

The angle of camera can be adjustable, you can set up 15 degree or 0 degree depends on FPV racing with Altitude Hold Mode or Manual Mode.

A spare voltage output port can be used for timer that designed for racing competition.

Throw and Flight at Any Angle

F121 Pro can be throws and starts to fly at any angle. A fixed head without a compass means the head of F121 Pro 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 Pro makes every beginner flight like a master.

Flight with FPV*

Experience a Different World

The advanced version of F121 Pro 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 angle of camera can be adjustable, you can set up 15 degree or 0 degree depends on FPV racing with Altitude Hold Mode or Manual Mode.

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.

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 Pro is full of childhood, a great gift for your son or daughter.

PID Autotuned

Easier for Drone Training

F121 Pro, with the flight controller F121 that with PID Autotune, can automatically correct the flight angle and easy to be controlled.

LED for Night Flight

F121 Pro support the LED (green and blue) for night flight, it is easy to recognize the direction even flight at midnight.

Four Flight Modes

Worry-free Practice

Beginners can start from Altitude Hold Mode to Stabilize Mode to Manual Mode and easily achieved the advanced level as a drone master.

At manual mode, high speed and unlimited rolling angle enabling the possibilities of different freestyle, pilots can fully enjoy the racing time.

The fourth mode is 360 Angle Flips that combine switch (CH7) with aileron or elevator sticks to perform cool aerial stunts.

High Speed at Altitude Hold Mode

Overcoming the defects of Euler angles singular value and using rotation vector algorithms, the flight controller F121 makes F121 Pro possible to rise and descend at high speed even with Altitude Hold Mode.

T8S, Perfect Partner of F121 Pro

Working with RadioLink 8 channels handle transmitter T8S*, F121 Pro reaches the range of 2000 meters (1.24Miles) in the air, ensuring complete fun both indoors and outdoors.

Noise Reduction by Software

Extend the Service Life

The noise reduction technology by software not only enables the motors of F121 Pro to work without noise during the flight but also makes them more responsive and efficient than traditional 8520 coreless motors, which ensures a longer life span.

FULLYMAX Battery

8 Minutes Racing Time

The battery of F121 Pro is 3.7V 660mAh 25C LiPo battery from FULLYMAX with a high-quality cell. The strong power and good heat radiation ensure 8 minutes of racing flight time.

* The flight time is tested with a new battery with full 4.2V.

GEMFAN Propeller

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.
