Hakrc 40A Mini F4 V2 Fly Tower

Integrated Flight Control and Power Distribution

The HAKRC 40A Mini F4 V2 Fly Tower integrates a flight controller, 4-in-1 ESC, and power distribution board (PDB) for streamlined micro builds. Powered by the STM32F405RGT6 CPU and ICM42688 gyroscope, it offers accurate flight data processing. With 16MB storage for flight logging and 5 UART serial ports for versatile connectivity, it supports 2S-6S LiPo batteries. The PDB efficiently distributes power to the 40A ESC, flight controller, and peripherals, with dual BECs (5V/2.5A and 10V/2A) ensuring stable voltage for cameras, VTX, and LEDs. The RX2 port connects to SBUS for reliable receiver integration.

Robust ESC and Safety Features

The integrated 4-in-1 ESC delivers 40A continuous current (45A peak for 10 seconds) and supports PWM, Oneshot125, Oneshot42, Multishot, Dshot150, Dshot300, and Dshot600 protocols. Running BLHeliSuite32Activator_16.7.14.9.0.3 firmware, it enables ESC telemetry data transmission to the VTX for real-time monitoring. Safety features include finger-tightened nut installation to prevent PCB damage, M2/M3 shock absorber balls for vibration protection, and guidelines to check pin alignment, polarity, and solder joints before powering on to minimize short circuit risks.

Compact Design with Seamless Integration

Measuring 31mm x 29.5mm (flight controller at 29mm x 29mm) with 20mm x 20mm mounting holes (Φ4mm), the 40A Mini F4 V2 Fly Tower is optimized for micro FPV builds. The 6P sky terminal seat (DJI-compatible) enables solder-free connections for GPS, TBS receivers, and cameras. Supporting 2S-6S LiPo batteries and external programmable LEDs, it includes accessories like a 35V/270uF capacitor, XT60 power head, M2x25mm screws, and cables (8P, DJI 6P, red/blue power) for simplified setup and enhanced reliability.

Enhanced User Experience

The HAKRC 40A Mini F4 V2 Fly Tower enhances the RC experience with:

• All-in-One Simplicity: Integrated flight controller, 4-in-1 ESC, and PDB reduce wiring for quick, clean micro builds.
• Stable and Precise Flight: The STM32F405 CPU and ICM42688 gyroscope ensure smooth, responsive performance for small quads.
