NewDarwinFPV "Cement" Ultra Durable F4 F7 100A Waterproof Stack

Waterproof Performance for Extreme FPV Flying

The DarwinFPV Cement Stack is engineered for pilots who fly where ordinary electronics fail. Featuring IP67 waterproof protection, a massive 100A ESC, and premium-grade components, it delivers reliable performance for freestyle, long-range, cinelifter, and demanding professional FPV applications. 

User Value: Fly with confidence in rain, over water, or challenging environments without worrying about electronics failure.

Fly Through Rain, Splash, and Water Landings

Unlike regular FPV stacks that can fail after moisture exposure, the Cement Stack features IP67 dustproof and waterproof protection and can withstand immersion in 0.5m of water for up to 30 minutes.

Innovative Structural Design

The Cement ESC uses an innovative sandwich stacking structure with 24 special bus bars, wafer-level heat conduction, and a glue soaking process. Compared with conventional ESC layouts, it improves overall current capacity by 4.8× and heat conduction efficiency by 5.8×. 

Uses a glue-filled, impact-resistant “cement potting” process to replace fragile connectors and traditional low-conductivity heat shells, enhancing shock resistance while maintaining compact size and installation compatibility.

F722 Computing Power Without Limit

Powered by the high-performance F722 processor, the Cement Stack supports dual 8K gyro/PID loops, bidirectional DShot600, and advanced Betaflight configurations with lower CPU load. 

User Value: Faster processing, smoother flight behavior, and more room for advanced tuning.

Smoother Motor Output and Finer Throttle Feel

The ESC supports 16–128KHz wide-range dynamic PWM output, automatically adjusting switching frequency based on flight conditions for more refined throttle control.

Premium Components & Protection

The Cement Stack uses premium components such as Toshiba MOSFETs, Murata ceramic capacitors, Panasonic low-ESR capacitors, DIODES TVS protection diode, 3oz copper thickness, and 6-layer HDI PCB. 

It also includes multiple protection systems: soft-start, reverse polarity, short circuit, overcurrent, and over-temperature protection.

Large Blackbox Storage

The F7 version includes massive onboard Blackbox storage that can record nearly 8,000 flight logs, while the F4 flight controller version provides 16MB Blackbox capacity.

Built for Tuning, Racing, and Long-Term Data Logging

Includes optional high-performance gyroscope choices (MPU6000 or ICM42688), onboard multi-level LED indicators for status checks, Pit Switch (F7 version), and extensive connectivity for easy integration in FPV builds.
