Hakrc 35A Mini F4 V2 Fly Tower

Integrated Flight Control and Power Distribution

The HAKRC 35A Mini F4 V2 Fly Tower combines 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 delivers accurate flight data processing. The 16MB storage supports flight logging, while 5 UART serial ports enable versatile connectivity. The integrated PDB efficiently distributes power from 2S-6S LiPo batteries to the 35A 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 is designated for SBUS, enhancing receiver compatibility.

Robust ESC and Safety Design

The integrated 4-in-1 ESC supports a continuous current of 35A (peak 40A for 10 seconds) and is compatible with PWM, Oneshot125, Oneshot42, Multishot, Dshot150, Dshot300, and Dshot600 protocols. Running BLHeliSuite32Activator_16.7.14.9.0.3 firmware, it supports 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, minimizing short circuit risks.

Compact Stack Design with Easy Integration

Measuring 31mm x 30mm (flight controller at 29mm x 29mm) with 20mm x 20mm mounting holes (Φ4mm), the 35A Mini F4 V2 Fly Tower is tailored for micro FPV builds. It features a 6P sky terminal seat (DJI-compatible) for solder-free connections, simplifying setup for GPS, TBS receivers, and cameras. Supporting 2S-6S LiPo batteries and external programmable LEDs, the tower includes accessories like an XT60 power head, a 35V/270uF capacitor, M2x25mm screws, and various cables (8P, DJI 6P, red/blue power) for enhanced reliability and ease of use.

Enhanced User Experience

The HAKRC 35A 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 and assembly time for cleaner, faster micro builds.
• Stable and Precise Flight: The STM32F405 MCU and ICM42688 gyroscope ensure smooth, responsive performance, while the 35A ESC powers small to medium motors reliably.
• Efficient Power Management: The PDB and dual BECs (5V/2.5A, 10V/2A) optimize power distribution, supported by a high-quality 35V/270uF capacitor.
• Wide Compatibility: Supports 2S-6S LiPo batteries, multiple receiver protocols (Frsky, Futaba, Flysky, TBS Crossfire, DSMX/DSM2 via SBUS on RX2), and Dshot600 for versatile setups.
• Safety and Durability: Shock absorber balls, installation precautions, and a compact design ensure longevity and safe operation in tight spaces.
