Let ChatGPT, Claude or Gemini guide your flight controller, GPS and telemetry setup from our verified docs — one prompt to copy, with you doing the physical steps.
Firmware Flashing Guide
How to flash ArduPilot, PX4, INAV or Betaflight onto an STM32 flight controller — DFU mode, bootloaders, the .hex / .apj / .px4 file formats, and recovery.
ArduPilot Basic Configuration
What a new ArduPilot multirotor has to be told before it can fly — frame type, ESC protocol, motor order, calibration, flight modes and arming checks.
PX4 Build & Configuration
Build and configure a PX4 multirotor end to end — ESC protocol, receiver, GPS and compass, orientation, calibration, telemetry, RSSI and battery setup.
ArduPilot FAQ
Answers to the questions ArduPilot builders actually ask — pre-arm failures decoded, motors not spinning, DJI OSD, bidirectional DShot and passthrough.
PX4 FAQ
Answers to the questions PX4 builders actually ask — ELRS and CRSF wiring, receivers that are never detected, missing baud parameters and battery readings.
INAV FAQ
Answers to the questions INAV builders actually ask — reordering motors, ESC protocols, receiver setup, board alignment in deci-degrees and CLI backups.
MicoAssistant Guide
Use the MicoAssistant web tool to configure MicoAir telemetry radios, optical flow and range sensors — drivers, wiring, baud rates and troubleshooting.
AIO or a Stack?
What an all-in-one board gives up against a flight controller and ESC stack — size, compass, OSD, BEC current, heat and repair cost, with a decision guide.
External Compass Orientation
Set the right compass orientation for a GPS or RTK module on ArduPilot, PX4, INAV and Betaflight — parameter names, value tables and how to check the heading.
GPS & Compass Guide
Fit a GPS and compass module to a drone and set it up on ArduPilot, PX4, INAV or Betaflight — mounting, wiring, parameters, calibration and pre-flight checks.
u-blox GPS Baud Rate
Change and permanently save a u-blox GPS module's baud rate in u-center — the fix for a GPS that worked on ArduPilot but is not detected by Betaflight.
Board Orientation
Tell the firmware how the flight controller is mounted — AHRS_ORIENTATION, PX4 Autopilot Orientation, INAV Alignment Tool and Betaflight board alignment.
