Yoetaun F405 BLS Flight Controller 4-in-1 ESC 50A 16MB Black Box

SKU CH-0CQ5-1DB5T

Combines an F405 flight controller with a 50 A 4-in-1 ESC, 16 MB black box and ICM42688P gyro in a 30.5 mm stack

  • Product colorBlue
  • Product typeF405 BLS
  • 16MB black box records flight data for post-flight analysis
  • ICM42688P gyro delivers stable flight control
  • Stack design saves space and simplifies cable routing
  • 50A continuous current with 55A burst handles demanding power needs
  • USB-C and 6 UART ports enable flexible connectivity

Targeted Flight Stack

The Yoetaun F405 BLS kit combines a 405-series flight controller with a 50A 4-in-1 ESC for FPV pilots who want integrated black-box logging and a compact stack. The 16MB onboard recorder captures full flight data for post-session analysis. A 42688P gyro feeds the STM32F405 MCU over SPI for responsive attitude control. Six UART ports and dual 5V/9V BEC outputs support varied peripheral configurations.

Plug-and-Play Assembly

The board pair uses a direct-plug Air Unit connection and 30.5mm mounting pattern, letting builders stack the 36.8mm controller atop the 42.9mm ESC with minimal wiring. Shock-absorbing grommets reduce the effective hole to 3mm, so verify frame compatibility before tightening. Soldering is still required for motor leads, receiver and VTX power; the OSD chip (AT7456E) and USB-C port are pre-mounted. Misaligned stack headers are the most common install issue.

Protocol and Current Ceiling

The ESC handles 50A continuous and 55A for five-second bursts, limiting propeller and battery choices to those within that envelope. Supported DShot rates top out at 600 alongside Oneshot125/42 and Multishot; faster protocols are not available. Black-box capacity is fixed at 16MB, capping log duration at high sample rates. The 30.5mm bolt pattern restricts use to frames designed for that standard.

Questions about this item

How do I confirm the 16MB black box is logging flight data after the first flight?

Connect the USB C port to a computer, open the configurator for the GEPRCF405 target, and download the black box file to verify recorded data.

What comes in the box and what must I supply separately for a complete stack?

The kit includes the F405 v2 flight controller with ICM42688P gyro, OSD chip AT7456E, dual BEC 5V and 9V, and the BLS50A 4-in-1 ESC rated 50A continuous, 55A burst; you add motors, propellers, battery, receiver, and frame.

Which ESC protocol should I select for the BLS50A 4-in-1 ESC running the G_H_30 target?

The ESC supports Dshot 150, 300, and 600 as well as Oneshot125, Oneshot42, and Mulishot; choose the highest Dshot rate your flight controller firmware allows for lowest latency.
