Flywoo Firefly 20PRO 4S HDZero ELRS

The Flywoo Firefly 20PRO 4S with HDZero video transmission system provides high-quality images, extremely low latency, and reliable communication during flight. Thanks to the fast video transmission technology, the pilot can precisely control the drone even during complex maneuvers or at high speeds, making this model perfect for both freestyle and racing FPV flying.

Features:

• Quick-change video transmission system – no soldering or additional calibration required;
• Factory-adjusted PID settings, maximum speed up to 120 km/h, stable flight without the "prop wash" effect;
• Sturdy carbon fiber frame with reinforced front arm for greater resistance to impacts and crashes;
• Integrated buzzer – easily find a fallen or lost drone with the push of a button;
• VTX, buzzer, receiver (RX) and GPS module can be connected without soldering – a plug-and-play solution, perfect for beginners;
• Shock-absorbing camera mount with adjustable 0°–25° camera angle effectively dampens vibrations and eliminates the „jello“ effect, so the image remains stable and sharp even when flying at high speeds.

Measurements:

Pure adrenaline. The compact frame hides a powerful 4S system. Only 22 % accelerators are needed for flight, and the maximum speed reaches 120 km/h. Lightning-fast response to control commands and plenty of power allow you to maneuver precisely in tight spaces and perform impressive freestyle and acrobatic maneuvers.

This model features a strong 2.5mm thick carbon fiber bottom plate for high load resistance. The one-piece front arm construction further increases the frame's rigidity and durability. Less worry about impact damage - more focus on flying and complex maneuvers.

The specially designed anti-vibration camera mounting system effectively suppresses high-frequency vibrations, so the transmitted image remains stable and clear. The adjustable 0°–25° camera angle allows you to easily adapt to both calm flights and fast racing or aggressive freestyle flying. Together with the HDZero Whoop Lite digital video transmission system, high-quality images, extremely low latency and reliable communication are ensured, providing a precise control feel and a smooth FPV flight experience even in the most challenging conditions.

The quick-release side covers not only give the drone a neat appearance, but also protect the most important electronic components. They help reduce the impact of drops or collisions, thus protecting the flight controller and video transmission system.

Forget about one of the most common problems with micro drones – damaged motor cables. The models are equipped with special motor cable protectors that reliably protect the cables from contact with propellers or damage during falls. All cables are neatly hidden and protected.

Firefly 20PRO is equipped with the new generation FLYWOO GOKU F405 20A SE AIO controller, whose compact design allows for efficient use of space in a small drone body. The GPS, receiver and video transmission system are connected using the "plug-and-play" principle, so no soldering is required during assembly or updates. The integrated sounder helps you easily find a fallen drone - the signal can be activated directly from the remote control.
