This X4320 350KV motor is a top-tier choice for professional builders and pilots who demand uncompromising power and reliability from their heavy-lift and long-range drone platforms.

X4320 350KV – Ultra‑High‑Power 12S Motor for 15‑17″ Heavy‑Lift & Industrial FPV Drone Motors

Delivering astonishing power density, the X4320 350KV is engineered for extreme heavy‑lift and long‑endurance applications. With a massive 43×20mm stator, 12S peak capability, and 3683W maximum power, this motor pushes the boundaries of what large FPV and industrial UAVs can achieve.

Key advantages:

• Monstrous power output – 3683W max (12S) per motor enables 6‑10kg+ payloads on quadcopters or 20kg+ on octocopters – ideal for cinema cameras, Li‑ion megapacks, or agricultural sprayers.
• 12S high‑voltage ready – Although rated for 6‑8S continuous, the 12S peak rating gives you a massive overhead for short‑duration bursts or custom high‑voltage setups. Perfect for professional applications requiring instant thrust.
• Optimized for 15‑17″ propellers – The 350KV winding paired with large, high‑pitch props (e.g., HQ15×7‑3) delivers incredible static thrust while maintaining low RPM efficiency for extended flight times.
• Efficient electrical design –
  – Idle current: 1.4A @ 10V – Excellent magnetic circuit efficiency.
  – Internal resistance: 46mΩ – Very low for this power class, reducing heat generation even under 80A loads.
  – Peak current: 80A (12S) – Realistic maximum for sustained heavy lifting.
• Premium 12N14P magnetic topology – Smooth, vibration‑free torque delivery for cleaner video and reduced mechanical stress on airframes.
• Robust mechanical construction –
  – 6.0mm steel bearing shaft – Withstands extreme torque and crash loads.
  – 51mm diameter × 40.5mm height – Compact for its power rating, fitting most 15‑17″ frames.
  – 297g weight (without wires) – Excellent power‑to‑weight ratio (12.4W/g).
  – 14AWG 400mm silicone leads – Thick, low‑resistance wiring for high‑current 12S setups.
• Wide operating voltage (6‑8S nominal, 12S peak) – Flexibility to run 6S for moderate flying or 12S for all‑out power.

Recommended applications:

• Professional heavy‑lift cinema drones (RED Komodo, Alexa Mini)
• Long‑endurance mapping & survey UAVs (12S Li‑ion)
• Agricultural spraying or cargo delivery drones
• X‑class (15‑17″) freestyle or racing

Recommended ESC: 80‑100A (12S rated, e.g., BLS 100A 12S or dual 80A)
Recommended propeller: 15×5 – 17×6 (two‑blade or folding)
Flight controllers: H7 / Cube / Pixhawk with 12S power module

The X4320 350KV is built for pilots and professionals who refuse to compromise on thrust, efficiency, or reliability. When you need to lift serious weight over serious distances, this motor delivers.
