NewBeeDrone F722 FC Hummingbird 305 Flight Stack

Binding the Built-in Receiver

လက်ခံသူ အမျိုးအစား- UART-based ExpressLRS Receiver

• Binding Mode ကိုဝင်ပါ။
  • Power Cycle x3: Power the FC on and off 3 times to enter binding mode (Blue LED double flash)
  • Betaflight 3.55 and above: After powering on, press the onboard button for 1–2 seconds to enter binding mode (Blue LED double flash)
• Enter Wi-Fi Mode
  • Wait 60 seconds: Without connection for 60 seconds after power-on, the receiver will enter Wi-Fi mode automatically (Blue LED fast flash)
  • Betaflight 3.55 and above: Long press the onboard button for 4 seconds to enter Wi-Fi mode (Blue LED fast flash)
• Firmware Update Note
  • Firmware name: NewBeeDrone Diversity 2.4GHz RX V2
  • Ensure you use the correct firmware. Flashing the wrong firmware can damage the receiver.

Using an External Receiver

• The internal receiver cannot be fully disabled — it can only be deactivated by disabling the corresponding UART.
• UART Assignments:
  • Hummingbird 200 FC → Internal RX on UART1
  • Hummingbird 305 FC → Internal RX on UART6

SD Card Recognition

• Maximum SD card size supported: 32GB
• Blackbox recording supports up to 4GB usable space
• SD card slot location is marked on the wiring diagram

AM32 ESC Settings

• Settings must be configured based on motor KV, motor pole count (magnet count), and timing.
• For high-KV race motors (e.g., 2207 2050KV): Set timing to 21.5° (maximum).
• Tested: 2150KV motors on 6S with 21.5° timing show no desync issues.
• PWM ကြိမ်နှုန်း -
  • Use fixed PWM — 48kHz is recommended for racing.
  • Floating PWM with sync is not recommended, especially for high-KV race motors.

Betaflight 4.6 Gyro Clock Sync

• The new Gyro Clock Sync feature in Betaflight 4.6 works automatically.
• No manual configuration is required.

Motor and Power Wire Soldering

• Both Hummingbird 200 and 305 ESCs use a 3D triple-side solder pad design.
• ဂဟေလုပ်နည်း-

1. Apply solder to both the top and bottom pads.
2. Place the wire into the center half-hole slot.
3.  Add solder to secure the wire in place.

• This ensures maximum electrical conductivity and mechanical strength.

Flight Controller Installation Precautions

• Before installation, check if any onboard components may touch the frame or other parts.
• Before tightening nuts, inspect from the side for possible contact points.
• If any parts are very close, cover them with insulating tape to prevent short circuits.

ကာကွယ်ထိန်းသိမ်းခြင်း။

• Apply conformal coating to both sides of the flight controller when possible.
  • Recommended for racing and freestyle flying.
  • Helps protect against dust, moisture, and debris that can cause shorts or component failure.
• This is a hobby-grade DIY product — damage caused during use is not covered under warranty.
• Every flight controller is 100% factory tested before shipping.

မှတ်ချက် - Please read this manual carefully before use. Proper installation and maintenance will greatly improve the product’s lifespan, reliability and performance stability.
