RadioLink F121 Pro 2KM FPV Racing Drone – 800TVL Cam, Altitude Hold, GEMFAN 65mm Props

Overview

The RadioLink Eneopterinae F121 Pro is an ultra-lightweight, feature-packed FPV racing drone built for education, training, and freestyle flight. Designed specifically for beginner to intermediate pilots, this micro drone weighs just 74.5g and features a durable carbon fiber and plastic frame with a 120mm diagonal wheelbase, making it ideal for indoor classrooms, outdoor practice, and drone racing clubs.

At the heart of the F121 Pro is the RadioLink F120 flight controller, which combines Kalman filtering with an inertial navigation system (gyro + accelerometer + barometer) to deliver highly stable altitude hold, even in tight indoor environments or low altitudes under 10cm. The drone supports four flight modes—Altitude Hold, Stabilize, Manual, and 360° Flip Mode—helping users advance from basic hovering to advanced acrobatics with ease.

The integrated 800TVL FPV camera, with adjustable angles (0° or 15°), and optional 5.8GHz DVR FPV goggles deliver a complete immersive flight experience. Meanwhile, the built-in PID autotune algorithm ensures optimal flight balance and responsiveness without manual tuning.

With a control range up to 2KM, up to 10 minutes of flight time, and protective features like GEMFAN propellers, snap-on guards, and noise-reduction software, the F121 Pro is not just a beginner drone — it’s a full-featured training platform perfect for learning, racing, and STEM education.

Details

The Eneopterinae F121 Pro Education and Training Kit makes it easy to go from zero to hero. It has altitude holding by inertial navigation and PID autotuned. The drone is small, making it easy to carry and use in small spaces indoors or outdoors. The camera angle can be adjusted between 15 degrees and 0 degrees, depending on the flight mode. A spare voltage output port allows for timer usage designed for racing competitions.

Four flight modes let beginners start with altitude hold mode, then stabilize mode and manual mode. From here, they can easily reach advanced levels as drone masters. In manual mode, high speeds and unlimited rolling angles enable freestyle possibilities, allowing pilots to fully enjoy racing.

F121 Pro uses Kalman filtering and inertial navigation for precise altitude control, ensuring stable flight in tight spaces or near surfaces. Ideal for kids flying drones indoors.

The High Speed Flight Controller Fl2 allows for precise altitude hold mode, overcoming Euler angle singular value defects using rotation vector algorithms, enabling smooth descent and ascent.

Throw and Flight at Any Angle. F121 Pro can be thrown and starts to fly at any angle. A fixed head without a compass means the head always remains the same direction if the rudder stick is not moved. Otherwise, it changes according to the rudder stick. With simultaneous response, F121 Pro makes every beginner flight like a master. The drone ensures smooth control and enhances user experience for beginners.

T8S, perfect partner for Fl21 Pro working with RadioLink, an 8-channel transmitter TSS*, reaches a range of 2000 meters (1.24 miles) in the air; ideal for indoor and outdoor use.

The Flight with FPV offers an immersive experience. Its advanced version features a 2SMW image transmission system, combining camera and OSD modules. Seamless connectivity to FPV displays or goggles ensures effortless flying.

EMAX TRANSPORTER 2 FPV Goggles provide stable signal, comfortable fit, integrated channel scanner, 1300mAh battery, auto DVR, playback, real-time feedback, and up to 32GB storage for a seamless FPV experience.

FULLYMAX Battery: 3.7V 660mAh 25C LiPo ensures 8 minutes of racing flight time with strong power and good heat radiation for RadioLink F121 Pro drone.

Noise reduction software enhances F121 Pro motors, ensuring quiet, efficient operation and extending service life compared to traditional 8520 coreless motors.

GEMFAN Propeller: This propeller uses aerodynamics and repeated testing to optimize performance. Its design focuses on weight and thickness distribution for a balanced and stable flight experience.

Propeller protection ensures safer training. Rectangular half-bale snap-type design protects pilots and prevents motor damage during collisions, maintaining flight performance.

USB LiPo Battery Charger CM120 offers high precision, safer charging, and longer lifespan for 1S LiPo batteries, ensuring 6-8 minutes of flight time.
