3D-Printed Airframe

The complete airframe design files are available on Thingiverse. This uses approximately 164 g of PLA at 30% infill.

• 1x lower plate
• 1x upper plate
• 4x arms
• 1x MPU-6050 frame
• 1x LM2596 frame
• 1x GoPro mount (if mounting camera)
• Antenna-mast components (3 pieces)

Mounting Hardware

Misc. hardware for assembling the quadcopter that you may already have lying around, and if not, can purchase at any local store.

• Screws
  • M3 Screw Assortment Kit
    • 4x M3×30mm - securing the 4 arms to the main body
    • 4x M3×8mm - securing motors (only if not included with motors)
    • 4x M3×8mm - securing GoPro mount to upper plate
    • 4x M3×12mm - securing MPU-6050 frame
    • 2x M3×8mm - securing LM2596 into its frame
    • 2x M3×12mm - securing LM2596 frame to body
    • 2x M3×16mm - antenna mast (bottom-to-arm and coupler-to-mast-top)
    • 3x M3×12mm - securing antenna base into mast coupler
  • M2*8mm pack
    • 4x M2×8mm - securing RPi Pico
• 4-inch zip tie pack (for strapping down components/wires)
• Double-sided foam tape for vibration-isolating the IMU

Radio Communication

• 1x Taoglas TI.10.0111 433 MHz antenna
• 1x 12-inch U.FL-to-SMA coaxial cable

Optional FPV Equipment

You can fly Centauri by eye (without any onboard cameras) if you want, and I did for a while! But if you want a "first person" perspective through an FPV monitor or goggles, you'll need these.

• 1x AKK BA3 all-in-one FPV camera/transmitter
• 1x JST-PH 2.0 connector
• 1x SoloGood FPV monitor or compatible analog FPV goggles
• 1x 3D-printed two-piece FPV protective frame

Miscellaneous

There is a good chance you have these on hand. But if not, here's what you'll need to get the work done and what I recommend.

• 1x Balance charger - safely charges the LiPo battery, balancing voltage across its individual cells
• 1x Soldering iron - for soldering all of the electrical connections throughout the build
