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).

High Speed at Altitude Hold Mode

Overcoming the defects of Euler angles singular value and using rotation vector algorithms, the flight controller CS360 makes F121 possible to rise and descend at high speed even with Altitude Hold Mode.

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.

Gensace Battery, 6–8 Minutes of Flight Time

Equipped with a Gensace battery, a well-known and trusted brand in the UAV industry, which uses high-quality battery cells to deliver strong power and reliable endurance. The battery features excellent heat dissipation, is resistant to swelling, and offers a long cycle life, ensuring continuous and powerful performance.

The battery connection utilizes a PH2.0 connector, ensuring a secure and stable connection that is difficult to loosen or disconnect.

Noise Reduction by Software Extends the Service Life

The noise reduction technology by software not only enables the motors of F121 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.

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.

Flight with FPV

Experience a Different World

The advanced version of F121 is equipped with a 25mW image transmission system that integrates a camera.

Connected with FPV displays or FPV goggles, flight becomes amazingly easy and intuitive.

All-Round Propeller Protection with Patented Design, Easier Installation and Removal

Featuring a patented rectangular semi-enclosed / fully enclosed clip-on propeller guard design, with a dual-sided, double-layer locking structure that reduces wear and tear on the propeller guards caused by repeated installation and removal over time.

The three-pillar support structure provides comprehensive protection for the propellers, preventing impact damage and protecting pilots from accidental contact with the spinning blades. Additionally, the propeller guards are directly mounted to the carbon fiber frame, eliminating the risk of motor misalignment or damage to the motor wires caused by crashes, which could otherwise affect flight performance.

Semi-Enclosed Propeller Guard Version

(Standard configuration for the F121 FPV transmission kit)

Fully Enclosed Propeller Guard Version

 (Standard configuration for the F121 Third-Person Ready-to-Fly kit; also available for purchase from the official RadioLink store)

First-Person Ready-to-Fly Version with Optional FPV Goggles or FPV Monitor, selectable in accordance with competition rules.

Fast Response with Virtually Zero Latency

The transmitter uses RadioLink’s latest T8S 8-channel portable gamepad-style controller with Bluetooth connectivity for mobile APP parameter tuning. It delivers a stable airborne control range of over 2,000 meters and supports hundreds of pilots competing simultaneously at the same venue without interference.

The RF system is based on the U.S. TI CC2500 chip and features the same gimbal assembly as the AT9S Pro, along with Japanese NOBLE potentiometers equivalent to those used by FUTABA, achieving the same stable 0.25 µs servo resolution as the AT9S Pro.

Control is smooth, precise, and highly responsive. Even in altitude-hold mode, the aircraft can perform rapid braking and instant stops, providing an international professional competition-level control feel right from the start.

Stabilize Mode

Four Flight Modes

The F121 comes with four flight modes.

Beginner pilots can gradually progress through altitude-hold low-speed mode, altitude-hold high-speed mode, and stabilize flight mode for training, allowing an easy transition from beginner to advanced pilot without long and tedious practice.

By default, the CH6 momentary switch on the transmitter is assigned to the one-key flip function. With stick-assisted control, the aircraft can perform left rolls, right rolls, forward flips, or backward flips.

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.

PID Self-Adaptive Control Makes Training Easy

The F121 supports automatic nose alignment and performs PID self-adaptation in real time during flight based on actual conditions. It intelligently corrects attitude and precisely finds the optimal flight state, delivering simple, easy, and precise control.

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.

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.
