Solder buzzer
Inspect all joints with magnifier

Day 3-4 • Build

Assemble the Drone

Mount everything to the frame. Route wires carefully.

Mount motors to arms with M3 screws
Stack FC + ESC with standoffs and grommets
Route and secure wiring with zip ties
Mount receiver antenna externally
Install FPV camera and VTX
Double-check all connections

Day 4 • Configure

Flash & Configure Firmware

Connect to computer via USB. Configure flight behavior.

Flash Betaflight / iNav via USB
Configure receiver protocol (ELRS)
Map channels and verify stick response
Calibrate accelerometer on flat surface
Set motor direction and prop rotation
Configure failsafe (cut motors or return-to-home)
Set battery voltage alarms

Day 4-5 • Test

Pre-Flight Checks

Critical safety checks before first power-up and flight.

Use SMOKE STOPPER on first power-up
Verify all motors spin (correct direction)
Check props are correct rotation (CW/CCW)
Verify radio link and response
Test arm / disarm (NO PROPS)
Check for vibrations, loose screws

Day 5+ • Fly!

First Flight

Open field, away from people. Start gentle.

Choose open field, no people nearby
Start in Angle mode (self-leveling)
Hover at 1-2 meters altitude first
Practice basic movements (forward, back, yaw)
Land and check for hot motors
Gradually increase confidence and altitude

Safety & Common Mistakes

What to watch out for. These will save you money, time, and possibly a house fire.

Critical Safety

LiPo Battery Safety

LiPo batteries can catch fire or explode if punctured, over-discharged, or overcharged. Always store in a fireproof bag. Never charge unattended. Never use a puffed or damaged battery. Dispose of properly.

Propellers Are Dangerous

Always remove propellers when working on the drone at your desk. Props spinning at 20,000+ RPM can cause serious lacerations. Never reach toward a spinning drone.

Smoke Stopper First

On first power-up, always use a smoke stopper (current limiter). One wrong solder connection can instantly fry your entire FC and ESC ($50-100 gone in a flash).

Common Mistakes

Printing

Using PLA for the frame (snaps on first crash). Going below 40% infill. Wrong print orientation (arms should be flat on bed). Not using hardened nozzle with CF filaments.

Soldering

Cold solder joints cause mid-flight disconnections. Use flux, heat properly, and inspect every joint. A magnifying glass helps catch bad connections.

Assembly

Incorrect motor rotation direction (check CW/CCW before props). Loose prop nuts. Unsecured wires vibrating into props. Not checking motor screw length (too long can puncture motor windings).

Flying

Starting in Acro mode (use Angle/Stabilize first). No failsafe configured. Flying in wind above 15 mph as beginner. Over-discharging battery (ruins it permanently).

Regulations

Check Local Laws

Most countries require drone registration above 250g. Typical restrictions: max altitude 120m (400ft), visual line of sight, no flying near airports or crowds. In the US, check FAA regulations at faa.gov/uas.

FPV Flying

In many jurisdictions, FPV flying requires a spotter (someone watching the drone with their eyes). Some countries require an amateur radio license for certain VTX frequencies.

Insurance

Consider drone liability insurance, especially for larger builds. Some flying clubs and organizations offer coverage as part of membership.
