X4-7 7inch Racing Drone with INAV Flight Controller

1. Product Overview

The X4-7 is a high-performance 7-inch drone designed for racing, aerial photography, and industrial inspection tasks. It features a 45A 4-in-1 ESC, INAV/BETAFLIGHT flight controller, 915MHz receiver, and a powerful 4S 5100mAh battery. With a maximum horizontal flight speed of 30m/s and up to 30 minutes of flight time, it delivers outstanding stability, responsiveness, and endurance for both professional and hobbyist pilots.

2. Key Features

(1) Electronic Speed Controller (ESC)
Equipped with a 45A 4-in-1 ESC, the X4-7 offers high-current support for motors under heavy load while reducing wiring complexity and minimizing the risk of system failure. This setup also helps lower the drone’s weight, contributing to smoother operation and greater flight efficiency.

(2) Flight Control System
The drone supports both INAV and BETAFLIGHT, two leading flight control platforms. INAV offers advanced attitude stabilization and precise sensor fusion for stable flight in challenging environments. BETAFLIGHT is known for its agile response and extensive customization, making it perfect for freestyle and racing pilots. Users can easily switch between the two based on application needs.

(3) Reliable 915MHz Receiver
The 915M receiver delivers reliable signal transmission with strong anti-interference performance. It ensures accurate command delivery for safe, controlled operation in complex environments.

(4) Battery System
Powered by a 4S 5100mAh lithium battery, the X4-7 offers high energy density and sustained output. Under standard conditions, it can achieve up to 30 minutes of flight time, significantly reducing downtime and improving efficiency across missions.

(5) Aerodynamic Structure
With a 7-inch wheelbase and compact design (25cm x 31cm without propellers), the drone balances agility and stability. Its 1.35kg frame is lightweight yet durable, making it ideal for navigating tight spaces or flying at high speeds.

(6) Outstanding Speed Performance
Capable of reaching a top horizontal speed of 30m/s, the X4-7 is built for speed-sensitive operations. Whether you’re racing or conducting rapid inspection over long distances, this drone meets the demand for fast deployment.

3. Application Scenarios

Aerial Photography
Thanks to its stable flight and extended runtime, the X4-7 can carry HD cameras to perform high-altitude image capture. Its flexibility and control accuracy make it suitable for dynamic shots and complex aerial filming.

Drone Racing
With its compact frame, powerful motors, and fast response times, the X4-7 excels in FPV racing. It handles tight turns and sharp climbs with precision, providing an adrenaline-pumping experience for racing enthusiasts.

Professional Tasks
For applications like precision agriculture, infrastructure inspection, and surveillance, the X4-7 provides long flight times and customizable payload support. It integrates easily with sensors and cameras, supporting data collection over large areas.

4. Customer Q&A

Q: Why is the drone equipped with a 45A ESC instead of higher amperage?
A: The 45A 4-in-1 ESC is a carefully selected balance between performance and efficiency. It delivers sufficient current for high-performance motors without adding unnecessary weight or complexity. Larger ESCs may offer more power, but they also increase weight and reduce flight time. This configuration optimizes both responsiveness and battery life.

Q: What’s the difference between INAV and BETAFLIGHT, and how do I choose?
A: INAV is ideal for stable, GPS-supported flight and is often used in photography and surveying. BETAFLIGHT is preferred for racing and freestyle flying due to its fast, responsive controls. If you’re prioritizing stability and automation, choose INAV. If agility and custom flight behavior are your focus, BETAFLIGHT is the way to go.

Q: Is the X4-7 suitable for beginners?
A: Absolutely. While the X4-7 is capable of professional-level performance, it includes flight modes and safety features ideal for new users. With optional beginner flight modes and our detailed guides, newcomers can safely learn to fly before advancing to more complex maneuvers.

Q: Will it really fly for 30 minutes?
A: Under standard flight conditions (steady speed, mild weather), the X4-7 can achieve up to 30 minutes of airtime. In more demanding scenarios such as racing or heavy maneuvering, flight time may decrease slightly. Even then, it offers superior endurance compared to most drones in its class.

Q: What if I encounter a technical issue or damage during flight?
A: We provide full technical support and after-sales service. If your drone experiences a malfunction, our expert team will assist you remotely or provide repair services. We also offer warranty coverage for non-human damages during the covered period.
