Description

The Ethix S4 series from HQProp delivers a refined aerodynamic profile tailored for high-speed FPV flight. The 5×3.65 configuration generates substantial thrust while maintaining manageable torque loads on 2207-2306 class motors, ideal for 4S to 6S LiPo setups.

Manufactured from high-grade polycarbonate, these props offer excellent rigidity and resistance to deformation at high RPMs, ensuring consistent performance. The Lemon Lime color provides high visibility for orientation during fast-paced racing or complex freestyle lines.

Key Features

High-visibility Lemon Lime polycarbonate construction for durability and orientation.
S4 airfoil design optimized for efficient thrust and reduced turbulence.
Precision-balanced hubs and blades for smooth, vibration-free operation.
Engineered for compatibility with high-KV motors on 4S-6S LiPo power systems.
Hub dimensions (12.8mm diameter, 6mm thickness) ensure secure mounting and alignment.

Applications

5-inch FPV racing drones requiring high top speed and aggressive cornering.
5-inch freestyle quadcopters for dynamic tricks and proximity flying.
High-performance builds utilizing 2207-2306 size motors on 4S-6S batteries.
FPV drones where high-visibility propellers aid in orientation and recovery.

Frequently Asked Questions

What size motors are these Ethix S4 5x3.65 propellers designed for?

These 5-inch props are optimally paired with 2207, 2306, or similar stator size brushless motors commonly used on 5-inch FPV racing and freestyle quadcopters. They are designed to handle the high RPMs generated by motors running on 4S to 6S LiPo batteries.

Are these propellers balanced and ready for flight?

HQProp manufactures the Ethix S4 series to high precision standards, resulting in well-balanced propellers straight from the package. For the ultimate in smoothness, especially on high-performance builds, a final dynamic balance check before flight is recommended.

What is the advantage of the polycarbonate material used?

Polycarbonate offers an excellent balance of rigidity, impact resistance, and weight. It maintains its shape under high centrifugal forces, providing consistent thrust, and is more durable against minor impacts compared to more brittle materials like standard nylon.
