The original design intention of the "cement" ultra-durable series of products:
How to make fpv drone break through the environmental limit again? To enhance the fun of flying for players, experience different flying perspectives, shoot different materials, and not be afraid of dust, rain, snow and any harsh environment.
We noticed that in order to prevent dust, tin slag, grass juice, rain, etc. from damaging electronic equipment, the pilots used methods such as anti-corrosion paint, printed parts, and bandages to protect the equipment. These methods are not only complicated and time-consuming, and do not comply with the manufacturer’s warranty policy. They also have low reliability and a high probability of failure.
To this end, Darwin launched a new "cement" ultra-durable series, so that you have more confidence to challenge the extreme environment. "Cement" - makes playing FPV drone more fun!

Why is it called "cement"?
Because it looks like cement and is potted, and has the same durability as cement, and we hope that your drones can be used safely and boldly in the water and mud!

"Cement" ultra-durable ELRS 2.4G receiver is a high-performance receiver specially designed for fpv drone. It has anti-reverse connection function,IP67 dustproof and waterproof rating, and 100mW power amplifier(PA), bringing a powerful, stable and reliable remote control experience.
