Technical Specifications & Features
Although a full specification sheet is not provided on the product listing, the GA8000 is designed for high-torque, heavy-duty applications. Below are expected parameters and design characteristics based on industry norms.
| Parameter | Expected Value | Importance |
|---|---|---|
| KV (RPM per volt) | 140 KV / 160 KV | Lower KV offers higher torque; ideal for large propellers |
| Max current / power | Refer to manufacturer datasheet | Determines safe operating envelope |
| Efficiency | High (typically ≥ 85%) | Drives endurance and heat generation |
| Mounting pattern | Standard UAV-compatible | Ensures straightforward installation |
| Bearing quality | High-quality bearings (e.g., NSK) | Improves reliability under load |
Why the Dualksy GA8000 Stands Out
- High power and torque: suited for heavy UAVs and large-diameter propellers.
- Versatility: suitable for both fixed-wing and multirotor platforms.
- Multiple variants: options in KV and axis configuration let you match mission needs.
- Supporting ecosystem: compatible mounts and bearings available from the same vendor.
- Manufacturer support: UAVMODEL offers related components and industry experience.
Applications
The GA8000 is suitable for a variety of professional and hobbyist UAV uses:
- Large fixed-wing drones used for mapping, surveying, and agricultural tasks
- Heavy-lift multirotors for payload delivery
- VTOL hybrid aircraft, where separate lift and cruise systems are used
- Long-endurance RC models
- Experimental UAV platforms requiring higher safety margins
Installation & Integration Tips
Mounting and Mechanical Fit
- Ensure the motor mount and airframe structure are rigid and can handle torque loads.
- Provide sufficient airflow or cooling ducts to dissipate heat during long flights.
- Use precise alignment and balanced propellers to reduce vibration and wear.
- Use proper grade fasteners and torque to secure the motor.
Propeller Matching
- Large-diameter props are generally optimal for lower-KV, high-torque motors.
- Always measure current draw at various throttle settings to ensure the prop does not overload the motor or ESC.
ESC and Power System
- Choose an ESC with continuous and burst current ratings above the expected motor load.
- Confirm battery voltage compatibility (for example, 6S or 8S systems).
- Use high-quality batteries with appropriate C-ratings to avoid voltage sag.
Testing and Calibration
Conduct ground tests before flight: log current, motor temperature, vibration levels, and thrust. Gradually increase throttle and inspect for abnormal sounds or heating.
Performance Considerations
- Thrust-to-weight ratio: maintain a safety margin suitable for the aircraft type (e.g., 2x for multirotors).
- Efficiency: impacts flight endurance and battery sizing.
- Thermal management: sustained loads require good heat dissipation strategies.
- Noise and vibration: dynamic balancing and dampers can improve longevity and stability.
Comparisons & Alternatives
When selecting a motor, compare GA8000 to other large-format brushless motors (for example, T-Motor or SunnySky offerings) by looking at thrust curves, efficiency, weight, and cost per watt. A complete manufacturer datasheet makes benchmarking much easier.
SEO Optimization Tips for the Product Page
- Include a detailed specification table with thrust, current, dimensions, and weight.
- Use relevant keywords such as "brushless motor for UAV", "high-torque drone motor", and "Dualksy GA8000".
- Provide descriptive alt text for all product images (for example: "Dualksy GA8000 brushless motor side view").
- Add customer reviews, case studies, and flight logs to build authority.
- Use structured data (Product schema, Review schema) for rich search results.
- Link to complementary products (ESCs, prop mounts, batteries) to increase internal linking.
Example Use Case
Scenario: A 5 kg fixed-wing UAV used for mapping missions with a 22×10 propeller and a 6S 10,000 mAh LiPo battery.
- Suggested motor: GA8000.8 160KV
- ESC: 100 A or higher, depending on measured peak current
- Estimated static thrust: 6–7 kg (verify with motor/prop/ESC test)
- Optimize battery life by tuning prop pitch and flight profile
Potential Risks & Considerations
- Motor weight may affect aircraft center of gravity—re-balance if necessary.
- Using overly aggressive propellers or excessive voltage can cause overheating or damage.
- Confirm authenticity and vendor support to avoid counterfeit or low-quality units.
- Account for lead times when planning builds or inventories.
Conclusion
The Dualksy GA8000 is a professional-grade, high-power brushless motor suitable for large UAVs and demanding RC aircraft applications. With careful integration—matching propellers, ESCs, and battery systems—you can achieve reliable, high-performance operation for both fixed-wing and multirotor platforms.
