Dry-fit autonomous quadcopter frame with carbon-fiber arms and motor mounts.

GPS quadcopter / MAVLink companion computer

Autonomous Drone Hardware Build

A sub-$450 carbon-fiber quadcopter platform built around ArduCopter, Raspberry Pi control, GPS navigation, and no-prop bench validation.

450mm motor spacing
4S LiPo power
1.89:1 target thrust ratio
MAVLink Pi to FC control

Build sequence

From arm assemblies to a powered center stack.

Each stage is documented with real build photos so the mechanical work, wiring, and bench checks are easy to audit.

Four carbon-fiber arm assemblies with yellow 3D-printed motor mounts and installed brushless motors.
01

Arm and motor assemblies

Carbon-fiber arms use yellow 3D-printed mounts with the brushless motors installed before final frame fitment.

Center hub with motor leads routed toward the electronics bay.
02

Center hub routing

Motor phase leads are staged toward the middle of the frame before trimming, ESC connection, and strain relief.

Raspberry Pi, flight controller, GPS module, and wiring mounted on the drone center deck.
03

Companion computer deck

The Raspberry Pi, Matek F405-Wing V2, and BN-880 GPS are staged together for GPS and MAVLink bench testing.

ESC bench test with XT60 leads, bullet connectors, and LiPo checker.

Electronics validation

Power checks before props ever go on.

The ESC and XT60 wiring are checked on the bench first. The layout keeps motor bullets visible, battery polarity obvious, and LiPo voltage readings available during early validation.

  • VBAT and GND short check with a multimeter
  • Motor phase connectors labeled before rotation testing
  • Flight controller, GPS, and Pi powered without propellers

Current state

Frame dry-fit is complete; calibration and MAVLink integration are next.

Complete

Frame layout

Four-arm carbon frame, motor mounts, and center plate fitment are documented.

Complete

ESC bench wiring

XT60 input, motor bullets, and early battery checks are validated.

In progress

Companion stack

Pi, flight controller, GPS, and jumper wiring are mounted for MAVLink testing.

Next

Calibration

Sensor calibration, motor direction checks, and first no-prop motor test.
