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

Darwin FPV "cement" ultra-durable waterproof stack is the top stack launched by the Darwin team for professional pilots. It completely solves the industry problem of poor reliability of fpv drones, allowing you to fly in any environment and greatly improving the fun of flying. Satisfy your various creative inspirations!
We have introduced many novel features on this stack, such as canceling all the easy-to-loose direct socket interfaces, canceling the traditional heat dissipation shell with low thermal conductivity, adding waterproof and impact-resistant treatment with glue filling, and adopting the ultra-high current MOS bus technology has added more than 10 core hardware protections, such as soft start protection circuit, anti-reverse connection, anti-short circuit and anti-overcurrent circuit, to ensure stability and reliability in extreme environments. And keep the product size and weight almost the same as ordinary stack, without affecting your installation compatibility and flying feel.

Spoiler:

1. The original design intention of the "cement" ultra-durable series of products:
How to make fpv drone break through the environmental limits again? To enhance the fun of flying for pilots, experience different flying perspectives, shoot different materials, and not be afraid of dust, rain, snow and any harsh environment.
We have noticed that in order to prevent dust, tin slag, grass juice, rain, etc. from damaging electronic equipment, the pilots have tried methods such as three-proof paint and printed parts to protect the equipment ,which not only have complicated processes, waste time, cannot be returned to the factory for warranty, but also have low reliability and high failure rates.
To this end, Darwin launched a new "cement" ultra-durable series, so that you have more confidence to challenge the extreme environment. "If you are afraid that the drone will fall due to accidents, please use cement!"

2.Why is it called "cement"?
Because its appearance is potted like cement, and it has the same strong durability as cement.
We have introduced many novel features on this stack, such as canceling all the easy-to-loose direct socket interfaces, canceling the traditional heat dissipation shell with low thermal conductivity, adding waterproof and impact-resistant treatment with glue filling, and adopting the ultra-high current MOS bus technology has added more than 10 core hardware protections, such as soft start protection circuit, anti-reverse connection, anti-short circuit and anti-overcurrent circuit, to ensure stability and reliability in extreme environments. And keep the product size and weight almost the same as ordinary stack, without affecting your installation compatibility and flying feel.

Darwin Care Card: 

This card is only valid when order the cement stack/FC/ESC and the care card at same time, if you just order the card and it will not work. 
With this care card, you can have 2 times to get 25% discount code on the cement stack/FC/ESC within 1 year. No matter what problems your stack/FC/ESC( wrong solder, be burned or whatever) and you only need to pay 75% of the cost to order a new one for your second order. 

Features: 

1: IP67 dust and waterproof rating, capable of withstanding immersion in 0.5 meters of water for 30 minutes without harm.
2: All products in the series are crafted using the highest-grade components, providing you with an unparalleled experience and top-tier enjoyment.
3: Both the F722 and F435 main control chips boast incredibly strong computing power, allowing for unrestricted full configuration operation.
4: Multiple protections including soft-start protection, reverse connection protection, short circuit overcurrent protection, and over-temperature protection ensure double the safety.
5: The innovative "sandwich" stacking scheme is employed in the electronic speed controller (ESC), offering greater current capacity, enhanced heat dissipation, and increased spatial utilization.
6: 128KHz dynamic PWM output for finer throttle control.
7: MPU6000 and ICM42688 gyroscopes optional .
8: Onboard 4G massive black box storage (16M capacity for F4 flight controller).
9: Onboard Pit Switch module (exclusive to F7 flight controller).
10: Onboard multi-level LED indicator lights for quick inspection of flight controller operation status.
