1S 1104 4300kV Brushless Mini FPV Motor

1S 1104 4300kV Brushless Mini FPV Motor delivers smooth, efficient thrust for micro quadcopters. Pilots use it on ultralight 65–80 mm builds to improve response, extend flight time, and keep noise low on indoor and backyard tracks.

Key Features:

• Optimized for 1S: Runs directly from a single-cell LiPo for simple, lightweight power systems.
• 4300kV Winding: Balances throttle resolution and efficiency for tight courses and freestyle.
• Compact 1104 Stator: 11×4 mm core delivers strong low-end torque for 2–3-inch props.
• Precision Bearings: Reduce vibration and improve motor longevity.
• Durable Bell and Shaft: CNC bell with hardened steel shaft resists crashes.
• Easy Rotation Swap: Reverse direction by swapping any two phase wires.

Technical Specifications:

• Configuration: 1104 brushless outrunner, 12N14P typical
• KV Rating: 4300 kV
• Voltage Range: 1S LiPo (3.0–4.2 V)
• Max Continuous Current: ~5–7 A on suitable prop and adequate cooling
• Recommended ESC: 5–10 A BLHeli_S/BLHeli_32, DSHOT compatible
• Propeller Size: 2.0–3.0 inch (51–76 mm), press-fit or T-mount depending on hub
• Wires: 3-phase silicone leads, ~30–60 mm length, pre-tinned

Mechanical Specifications:

• Motor Frame: Aluminum alloy bell, steel shaft
• Bearings: Dual micro ball bearings
• Mounting Pattern: 9×9 mm M2 (standard for 11xx motors)
• Prop Mount: 1.5 mm shaft or T-mount (verify variant)
• Finish: Anodized bell with balanced rotor

Dimensions:

• Stator Size: 11 mm diameter × 4 mm height
• Motor Diameter: ~14 mm (bell outer)
• Motor Height: ~16–18 mm including shaft
• Shaft Diameter: 1.5 mm
• Weight: ~5–6 g (without wires)

Pinout and Wiring:

• Three Phase Leads: Connect to ESC pads A, B, C in any order.
• Rotation Direction: Swap any two leads or set reverse in ESC firmware.
• Power Path: Battery → FC/ESC (1S) → Motor. Keep leads short to reduce losses.
• Prop Fitment: Use correct hub (press-fit or T-mount screws) and balance props to reduce vibration.

Datasheet Reference:

• Refer to the manufacturer’s datasheet for thrust curves, efficiency tables, and mounting drawings for the 1104 4300 kV variant.

Applications:

• Micro FPV Quads: Power 65–80 mm toothpicks and whoops on 1S packs.
• Indoor Racing: Deliver precise throttle control in tight spaces.
• Cinematic Micro Builds: Carry lightweight HD or AIO cameras with smooth response.
• STEM and Prototyping: Use for small robotics and UAV experimentation.

Equivalent Models:

• 1103 5000–6500 kV: Lighter option for ultra-micro props.
• 1104 5000–6000 kV: Similar torque with slightly higher RPM on 1S–2S.
• 1202.5 5000–8000 kV: Alternative stator geometry for lightweight frames.

Package Includes:

• 1 × 1S 1104 4300 kV Brushless Mini FPV Motor
