Detailed specification

Integrated and Robust Design

The HAKRC F4126 AIO combines a flight controller and a 4-in-1 ESC on a single 32x32mm board, simplifying wiring and saving space in compact FPV drone builds. Its high-end 8-layer PCB with 2oz thickened copper skin enhances overcurrent capability and provides excellent heat dissipation. This robust construction ensures durability and reliable performance, making it ideal for demanding micro drone applications.

Quality Components for Flight Stability

At its core, the F4126 AIO features the STM32F411CEU6 CPU and ICM42688 IMU, delivering responsive flight control with the HAKRCF411D firmware. The ESC section incorporates imported 30V high-current-resistant MOSFETs for longevity, an industrial-grade LDO for high-temperature resistance, and high-quality Japanese Murata capacitors for superior filtering performance. These components ensure stable and dependable operation across various flight conditions.

Feature-Packed for Modern FPV

The F4126 AIO is equipped with an AT7456E chip for On-Screen Display (OSD), an integrated barometer for altitude sensing, and a 16MB black box for flight data logging. It includes a 5V/3A BEC to power peripherals, a built-in current sensor, and support for adjustable LEDs. The integrated 20A ESC (25A peak) runs BLHELI_S (G-H-30) firmware, supporting PWM, Oneshot125, Oneshot42, Multishot, Dshot150, Dshot300, and Dshot600 protocols on 2S-5S LiPo input.

Enhanced User Experience

The HAKRC F4126 20A AIO enhances the FPV experience with:

  • Streamlined Builds: The all-in-one design reduces components and soldering, enabling quicker, cleaner, and lighter micro drone setups.
  • Stable and Responsive Flight: The STM32F411 CPU and ICM42688 IMU provide smooth, precise flight performance with modern firmware support.
  • Reliable Power Delivery: The 20A ESC with quality MOSFETs, LDO, and Murata capacitors ensures consistent power and heat management in compact builds.
  • Onboard Diagnostics: The 16MB black box and AT7456E OSD enable flight data logging and real-time FPV feed information for tuning and troubleshooting.
  • Peripheral Support: A 5V/3A BEC powers receivers, VTX, and cameras, while adjustable LED support adds customization.
  • Wide Compatibility: Supports multiple receiver protocols (Frsky, Futaba, Flysky, TBS Crossfire, DSMX/DSM2) and ESC protocols (up to Dshot600) for versatile FPV setups.

Lightweight Performance Beast

This AIO is a game-changer at just 7g! Perfect for my 3-inch whoop, the ICM42688 IMU is super precise, and PID tuning is a breeze. The 20A ESC handles 2S-5S like a champ, no overheating. 8-layer PCB feels premium, and soldering is buttery smooth. Murata caps keep signals clean. Insane value—highly recommend for lightweight builds!

Thank you for the awesome review! We're thrilled to hear you love the HAKRC F4126 20A AIO's performance and lightweight design. Your support means a lot—happy flying, and we look forward to serving you again!

Minor Firmware Hiccup

This AIO rocks: 8-layer PCB, solid 20A ESC, and clean Murata filtering. Flysky receiver paired easily, and the OSD is sharp. Had a small firmware glitch when updating to BLHELI_S, but HAKRC’s site fixed it. Would give 5 stars with better docs.

We appreciate your honest review! We’re addressing the firmware update issues and improving documentation. We’ll reach out via email with updated guides and support to make things easier. Thanks for choosing HAKRC!

Solid with Small Flaws

Really solid AIO—5S support, precise IMU, and adjustable LEDs are awesome. Solder pads are great, and the 16M blackbox is a tuning lifesaver. Manual is a bit vague, and barometer setup took some trial and error. Still, flies amazingly well for the price!

Thank you for your feedback! We’re sorry for the unclear manual and barometer setup issues. Our team is revising the documentation, and we’ll email you with detailed instructions and support to optimize your experience. Glad you’re enjoying the flights!

Bang for Buck

Got this AIO for under $50, and it’s a steal! STM32F411 chip is snappy, ICM42688 IMU tunes perfectly. Dshot600 support and 20A ESC handle 5S flawlessly. 16M blackbox logs are clear for freestyle tuning. Only nitpick is the basic packaging, but the board itself is flawless.

We’re stoked to hear you’re loving the value and performance of the HAKRC F4126 20A AIO! Thanks for the feedback—we appreciate your support and will keep pushing for top-notch quality. Happy freestyle flying!

Great but Tricky Setup

Awesome AIO—20A ESC pushes 4S great, and the blackbox is super useful. Solder pads are clean, and ICM42688 is precise. Only gripe is the initial firmware setup; Betaflight needed some tweaking. Not newbie-friendly, but once configured, it flies like a dream. Great value!

Thanks for your feedback! We’re sorry to hear about the tricky firmware setup. Our team is working to improve user-friendliness, and we’ll email you with detailed setup guides and support options to ensure a smoother experience. Appreciate your review!
