5. Setup & Wiring

Careful attention to wiring is crucial for the proper and safe operation of your flight stack. Refer to the diagrams below for correct connections.

5.1 ESC Wiring Diagram

Connect your motors and battery to the ESC as shown. Ensure correct polarity for the battery connection. The included capacitor should be soldered to the main battery pads (BAT+ and BAT-) on the ESC to filter power noise.

5.2 Flight Controller Connections

The F765 Flight Controller supports various peripherals. Connect your camera, VTX (Video Transmitter), RC Receiver, GPS, and Buzzer according to the diagram. Pay close attention to the correct UARTs and power pins.

5.3 Kuisa Stack

Mount the flight stack onto your drone frame using the provided screws, nuts, and rubber grommets. The soft mounting grommets are essential for reducing vibrations transmitted to the flight controller's gyroscopes, improving flight performance.

6. Operating Instructions

After completing the physical installation and wiring, proceed with the software configuration and initial flight checks.

6.1 Kupenya kweFirmware uye Kugadzirisa

1. Batanidza kuPC: Use a USB cable to connect the flight controller to your computer.
2. Isa Madhiraivha: Ensure necessary drivers (e.g., STM32 Virtual COM Port Driver, Zadig for DFU mode) are installed.
3. Flight Controller Firmware: Open Betaflight Configurator (or your preferred flight control software). Select the correct target for the F765 FC (e.g., HGLRCF765) and flash the latest stable firmware.
4. Firmware yeESC: Use BLHeliSuite32 to update and configure the ESCs. Ensure all ESCs are running the same firmware version.
5. Kutanga Configuration: Follow the standard Betaflight setup wizard for sensor calibration, motor direction, receiver setup, and mode assignments.

6.2 Pre-Flight Checks

• Iva nechokwadi chekuti kubatana kwese kwakachengeteka uye kwakanangana nemazvo.
• Check motor spin direction in Betaflight Motors tab (with propellers removed).
• Confirm receiver inputs respond correctly in Betaflight Receiver tab.
• Ita shuwa bhatiri voltage and current sensor readings are accurate.
