Collection: 5 inch props

5 Inch FPV Propellers

5 inch propellers (5") are the most popular propeller size in FPV drone racing and freestyle flying. Compatible with 2204–2306 motors and typically paired with 4S or 6S LiPo batteries, 5" props offer the ideal balance of thrust, efficiency, and durability for both competitive racing and freestyle aerobatics.

Why 5 Inch Props Are the FPV Standard

The 5" prop size has become the dominant choice in FPV because it delivers high thrust-to-weight ratios on lightweight 5" freestyle and racing frames, while remaining manageable in terms of motor load and battery draw. Most 5" builds weigh between 250g and 400g all-up weight, making them agile and responsive.

Types of 5 Inch Propellers

• Tri-blade (3-blade) Props – The most common choice for freestyle and racing. More thrust and better handling than bi-blades, with a slight efficiency trade-off. Popular options include the HQProp 5×4.3×3 and Gemfan 51466.
• Bi-blade (2-blade) Props – More efficient and quieter. Preferred for long-range or cinematic FPV builds where flight time matters more than raw punch.
• Quad-blade (4-blade) Props – Maximum thrust and braking force. Used in power-focused freestyle builds or heavy-lift 5" quads.
• Toothpick / Ultralight Props – Designed for sub-250g 5" builds. Lightweight and efficient, optimised for low-KV motors.

Featured Brands

• HQProp (High Quality Propeller) – A leading FPV propeller manufacturer known for precision-moulded, durable props. Their 5" range includes the popular HQProp 5×4.3×3V1S and HQProp ETHiX series, trusted by professional freestyle and racing pilots worldwide.
• Gemfan – One of the most widely used propeller brands in the FPV community. Gemfan's 5" lineup — including the iconic Gemfan 51466 and Gemfan Hurricane series — is renowned for consistent quality, excellent thrust characteristics, and broad motor compatibility.

How to Choose the Right 5" Prop

• Pitch – Higher pitch (e.g. 4.8 or 5.1) = more top-end speed. Lower pitch (e.g. 4.3) = better acceleration and efficiency.
• Blade count – More blades = more thrust and drag. Fewer blades = more efficiency.
• Material – Polycarbonate (PC) blends offer durability; glass-fibre reinforced props are stiffer and more efficient but less forgiving on crashes.
• Motor KV compatibility – Match prop pitch and diameter to your motor KV. Most 5" freestyle motors run 2300–2600KV on 4S or 1700–2100KV on 6S.

Frequently Asked Questions

What is the best 5 inch prop for freestyle FPV? The Gemfan 51466 and HQProp 5×4.3×3V1S are widely regarded as the best all-round 5" freestyle props, offering a good balance of thrust, efficiency, and durability.

Are 5 inch props compatible with 4S and 6S? Yes. Most 5" props are designed to work with both 4S and 6S LiPo batteries, though motor KV should be matched accordingly — higher KV for 4S, lower KV for 6S.

How many props do I need for an FPV build? A standard quad uses 4 propellers (2 clockwise, 2 counter-clockwise). It's recommended to keep several spare sets, as props are consumable and break on crashes.
