About the Nazgul DC5 ECO O4

The Nazgul DC5 ECO O4 is a lightweight 5-inch DeadCat FPV drone designed for pilots who want DJI O4 image quality, clean HD FPV video, and a more affordable alternative to premium Evoque models.

Its DeadCat geometry helps reduce propellers in the camera view, making it practical for cinematic freestyle, smooth cruising, action-camera footage, and general HD FPV flying.

The frame combines carbon fiber with an aluminum camera mount, while the integrated Anti-Spark Filter, built-in buzzer, receiver mounting area, and DJI O4 Air Unit Pro make it a clean and practical BNF platform.

Compared with the Nazgul Evoque F5 V3 O4, the DC5 ECO is the lighter and more affordable DeadCat option. The F5 V3 remains the premium model with Evoque side panels, switchable DeadCat / True X configuration, and higher-end frame design.

Highlights

Custom ReadyFly Combo
Build your own FPV setup around the Nazgul DC5 ECO O4. Select the drone, goggles, controller, batteries, charger, and useful accessories according to your needs.

5% Bundle Discount
Select 7 or more eligible products from this ReadyFly Combo and receive 5% discount on all selected bundle products.

Lightweight 5-Inch DeadCat Platform
The Nazgul DC5 ECO combines a carbon fiber frame with an aluminum camera mount. Its DeadCat geometry helps reduce propellers in view, making it well suited for DJI O4 footage, cinematic flying, and action-camera use.

DJI O4 Air Unit Pro
The DJI O4 Air Unit Pro provides a clear low-latency digital FPV feed with up to 1080p/100fps live view, depending on goggles, region, environment, and local regulations.

The O4 Air Unit Pro also supports onboard recording up to 4K/120fps, giving pilots high-quality footage directly from the air unit without requiring an additional HD camera for every flight.

4K Stabilized Video with 155° Ultra-Wide Angle
With its 1/1.3-inch image sensor, 155° ultra-wide field of view, and support for RockSteady stabilization or gyro data for Gyroflow, the DJI O4 Air Unit Pro delivers high-quality onboard footage for freestyle, cinematic, and cruising flights.

Anti-Spark Filter
Connecting a high-voltage LiPo battery can create a visible spark at the XT60 connector, caused by the initial current rush into the ESC and capacitor system. The integrated Anti-Spark Filter helps reduce plug-in spark, protects the connector from unnecessary wear, and helps reduce sudden voltage and current spikes during battery connection.

ND Filter Support
Compatible ND filters can be used to better control exposure, shutter speed, and motion blur in bright conditions. Please use ND filters designed for the iFlight O4 Air Unit Pro setup, as DJI original O4 Pro filters may not fit this drone design correctly.

Practical Maintenance Features
The DC5 ECO is equipped with a built-in buzzer and a dedicated receiver mounting area, making setup, maintenance, and receiver access easier and cleaner.

Flexible Build Layout
The frame provides standard 20×20mm and 30.5×30.5mm mounting options, offering flexibility for maintenance, repairs, and future customization.

Pre-Installed BLITZ Mini M10 GPS V2
GPS can support positioning, telemetry, and Betaflight GPS Rescue when correctly configured and tested by the pilot. GPS Rescue is not enabled by default and should not be treated as a replacement for safe piloting, a strong radio link, and proper failsafe setup.

BNF Drone Setup

The drone inside this ReadyFly Combo is a BNF drone, which means Bind-and-Fly.

It comes assembled and factory configured with a Betaflight preset already installed. No firmware update, reset, or Betaflight changes are required before the first flight.

The drone still needs to be bound to a compatible radio controller before flying.

Angle Mode is enabled by default to make first flights safer and reduce the risk of accidents during initial setup.

ReadyFly Combo vs BNF Drone Only

Choose the ReadyFly Combo if you want to select multiple compatible products together, such as goggles, controller, batteries, charger, and accessories.

Choose the BNF drone only if you already have compatible goggles, controller, batteries, charger, and tools.

This ReadyFly Combo is especially useful for beginners because it helps reduce missing parts, wrong controller choices, wrong battery choices, and charger compatibility issues.

Choose the Correct Receiver / Control Version

Please choose the drone version that matches your radio controller.

Available receiver/control versions:

• DJI FPV Remote Controller 2/3
• TBS Crossfire Nano RX
• iFlight ELRS 2.4GHz RX
• iFlight ELRS 868/915MHz RX

The DJI O4 Air Unit Pro handles the video link. The selected receiver/control version determines how the drone receives radio-control input.

DJI Controller Version
Choose the DJI version if you want to control the drone with DJI FPV Remote Controller 2 or DJI FPV Remote Controller 3.

This version is configured for DJI SBUS control. Additional SBUS and GND wires are connected to the flight controller for DJI remote-control input.

Important: The DJI Controller version is intended for DJI remote control use. To use ELRS or TBS Crossfire instead, a separate receiver must be installed and correctly configured. This may require disconnecting the DJI SBUS wiring or using another UART for receiver input.

ELRS 2.4GHz Version
Choose this version if you use an ELRS 2.4GHz radio, such as an iFlight Commando 8 or Commando 14 ELRS 2.4GHz.

ELRS 868/915MHz Version
Choose this version only if your radio or module supports ELRS 868/915MHz.

ELRS 2.4GHz and ELRS 868/915MHz are not compatible with each other.

TBS Crossfire Version
Choose this version if you use a TBS Crossfire radio or module.

If you are unsure which version fits your radio, contact us before ordering.

FPV Goggles Compatibility

The DJI O4 Air Unit Pro is compatible with:

• DJI Goggles 3
• DJI Goggles N3
• DJI Goggles 2
• DJI Goggles Integra

Please choose goggles according to your budget, features, and controller choice.

Important: Goggles handle the video link. The radio controller or receiver handles control input. These are separate systems and must both be compatible.

Battery Recommendations

This drone is designed for 6S batteries.

Most pilots use batteries between 1380mAh and 2400mAh.

Freestyle / responsive flying:

6S 1380–1550mAh high-discharge LiPo

Cinematic / GoPro flying:

6S 1550–1850mAh high-discharge LiPo

Longer cruising:

6S 1850–2400mAh high-discharge LiPo

Maximum endurance / smooth cruising only:

DOGCOM 6S1P 4000mAh Li-Ion
DOGCOM 6S1P 5000mAh Li-Ion

Important Li-Ion Note

Li-Ion batteries are only recommended for smooth cruising and endurance-focused flying.

They are not suitable for aggressive freestyle, racing, repeated punch-outs, or high-current flying.

Li-Ion batteries behave differently from LiPo batteries and may require adjusted Betaflight voltage warnings.

Charger Recommendations

Choose a charger that supports 6S LiPo batteries and balance charging.

For one or two batteries, a dual-channel charger can be practical.

For compact travel setups, a USB-C PD charger may be suitable, depending on charging power and battery size.

Always use the correct battery type, cell count, charge current, and balance mode when charging.

Action Camera Support

The DC5 ECO frame can be used with compatible action-camera TPU mounts.

A GoPro-style action camera can be mounted for cinematic footage, but the final flight feel and flight time depend heavily on battery size, camera weight, propeller choice, and flying style.
