Why This Build Works for Heavy Lifting
1. Motor + Prop Matching
4214 440KV motor + 1310 3‑blade propeller provides enough torque for 6‑7kg payload without overheating. 8S voltage keeps current moderate while delivering high power.
2. Dual Battery Configuration
Two 8S 8000mAh packs in parallel extend endurance. 38 min unloaded / 11 min at 10.9kg is realistic for industrial tasks.
3. Strong Frame & Power System
10mm arm thickness + 600mm wheelbase ensures stability under heavy load. 80A ESC per motor gives headroom for sudden throttle spikes.
Best Use Cases
- Agricultural spraying (20‑25L tank equivalent)
- Industrial cargo delivery (6‑7kg goods)
- Long‑range mapping & inspection (15km VTX range)
- Heavy‑lift testing for R&D
