Very durable BEC

1S whoop drones often fly at only 3.3V, and digital video transmission requires higher current, which puts a heavy load on the BEC. For this purpose, an advanced BEC has been developed that can deliver more than 3A of current even at a very low voltage of 2.85V. This ensures stable video transmission in critical situations. Although flying at such low voltages is not recommended, this innovation gives pilots the opportunity to save the drone in unexpected situations.

Improved 12A ESC

• The Matrix 1S FC offers an ESC with 12A continuous and 18A peak current, ensuring reliable performance and an optimal thrust-to-weight ratio.

Separate power line for IMU

• Independent 3.3V LDO supply for IMU eliminates interference, improving accuracy and stability during flight.

Whoop-ready installation

• The 3IN1 version has motor connectors and a SH1.0 6-pin HD port, making installation and maintenance simple and without soldering.
