1S 1104 4300kV Brushless Mini FPV Motor

1S 1104 4300kV Brushless Mini FPV Motor provides exceptional power and efficiency for ultra-lightweight micro drones and indoor “whoop” style quadcopters. This high-performance motor utilizes a precise 4300kV rating to deliver smooth, controllable throttle responses on a 1S LiPo battery setup. Consequently, pilots experience a perfect balance between flight time and agility during intense FPV racing or freestyle maneuvers. Furthermore, the lightweight 1104 stator design ensures that your aircraft maintains a low moment of inertia for rapid directional changes. Therefore, choosing this brushless motor allows you to upgrade from traditional brushed systems to a more durable, reliable, and powerful propulsion solution for your micro FPV fleet.

Key Features:

• High-Efficiency 1S Design: Engineers optimized this motor specifically for 3.7 V to 4.35 V operation, ensuring maximum thrust output from a single-cell LiPo battery.
