The FLYCOLOR BLS 04 F4 65A 3-6S Stack combines a 4-in-1 ESC and a flight controller. The two-layer tower design with dampers between them reduces vibration. The ESC based on EFM8BB21 operates up to 50MHz and supports BLHeli-S/Bluejay with a continuous current of 65A and a peak of 70A. The STM32F405 controller with MPU-6500 gyroscope and BMP388 barometer provides stabilization and altitude control. Built-in BEC 3.3V/5V/9V power the receiver, VTX, camera, LEDs, and more. SBUS, CRSF, and SPEKTRUM protocols are supported. Compact dimensions of 45*41*16.5mm and standard 30.5*30.5mm mounting simplify installation.
