BlueBoy Getting Started Guide

A hand-built, high-performance 5-inch Betaflight aircraft. DJI O4 Pro supplies the digital view; it does not fly the quad for you.

Real FPV, serious power. Never arm around people, pets, vehicles, indoors, or on a workbench. Remove every prop before Betaflight motor, receiver, ESC, or failsafe work.

Your package

Aircraft

BlueBoy custom 5-inch FPV with DJI O4 Pro, ELRS receiver and GPS.

Controls

RadioMaster Pocket Crush Frost Blue, bound and configured with basic modes.

Video

DJI Goggles N3 paired to O4 Pro with OSD verified.

You provide

Healthy 6S XT60 LiPos, commonly 1000–1300mAh, and a proper balance charger.

Startup and shutdown

RADIO → GOGGLES → QUAD

ARM switch off; throttle fully down.
Power the Pocket and confirm the expected controls.

Confirm ELRS link/telemetry, O4 video, OSD, battery voltage and GPS status.

DISARM → UNPLUG QUAD → GOGGLES OFF → RADIO OFF

Props, Betaflight and controls

Do not copy a generic prop diagram. BlueBoy must use the motor direction and prop orientation configured for this aircraft. Photograph the layout before removing props. With props off, verify roll, pitch, yaw, throttle, ARM, modes, FC orientation and failsafe. Save a Betaflight backup before changing rates, presets or firmware.

GPS Rescue

GPS Rescue is not DJI Return-to-Home. Acquire satellites, verify home position, hover throttle, altitude and failsafe settings, and test only in a large open area.

First flight

Frame, arms, props, prop nuts, antennas, camera, GPS, wiring and strap inspected
Healthy 6S battery secured; leads clear of props
Radio link, switches, video and OSD confirmed
Short low hover, gentle inputs, then land and inspect
Check motor temperature and stop if anything is unusually hot, rough or vibrating

BlueBoy rule: if the video, radio, sound, vibration or battery sag feels wrong, land. A controlled landing is cheaper than an exciting tree investigation.
