Description

The Pro-Range Floppy Proppy 4019-2 propellers are engineered for 4-inch FPV drone builds requiring a blend of responsive handling and efficient power delivery. The 1.9-inch pitch provides a solid thrust-to-weight ratio suitable for aggressive freestyle maneuvers and technical racing tracks.

Manufactured from high-grade polycarbonate, these propellers offer a robust yet flexible structure that can withstand minor impacts while maintaining precise blade geometry for consistent flight performance. The clear gray finish aids in visual orientation during flight.

Key Features

High-performance airfoil design optimized for 4-inch quadcopter frames.
Durable polycarbonate (PC) construction resorts to cracking and deformation.
Press-button assembly system ensures a secure and reliable blade-to-hub connection.
Precision balanced for smooth operation and reduced motor vibration.
Lightweight design (1.42g per propeller) maximizes flight time and motor responsiveness.
Compatible with T-mount motor shafts for a secure fit.

Applications

4-inch FPV racing drones built on lightweight frames like the Apex 4" or ImpulseRC Apex.
4-inch freestyle quadcopters requiring durable props for proximity flying and trick execution.
Micro long-range 4-inch builds where propeller efficiency directly impacts flight time.
3S-4S powered 4-inch Cinewhoop platforms for smooth, controlled aerial footage.

Frequently Asked Questions

What motor size and KV range are these 4019-2 propellers designed for?

The Pro-Range 4019-2 propellers are optimized for 1505-size brushless motors with a KV rating in the 1505-3500KV range. This combination is typical for high-performance 4-inch FPV drones running on 3S or 4S LiPo batteries, providing an ideal balance of torque and RPM for responsive flight characteristics.

How do I assemble the propellers with the press-button mechanism?

The propellers feature a press-button assembly system. Align the propeller blade root with the corresponding slot in the hub and press firmly until you hear or feel a definitive click, indicating the locking mechanism has engaged. Ensure each blade is fully seated and secure before flight to prevent separation during operation.

Are these propellers suitable for 5-inch or 6-inch drone frames?

No, these are specifically 4-inch diameter propellers. Using them on a larger frame, such as a 5-inch or 6-inch quadcopter, would result in insufficient thrust and poor flight performance. Always match propeller diameter to the designed frame size and motor capability for optimal efficiency and control.

What is the advantage of the polycarbonate (PC) material?

Polycarbonate offers an excellent strength-to-weight ratio, providing high impact resistance compared to more brittle plastics like nylon. This makes the 4019-2 propellers more durable in crashes, capable of bending slightly without snapping, which is crucial for the high-risk environment of FPV freestyle and racing.
