Building and setup

How to build an FPV drone

An FPV drone consists of a frame, four motors, a flight controller and ESC (together called the stack), an FPV camera, a video transmitter (VTX), a receiver and propellers — plus a radio, goggles and batteries. You solder the parts together and configure them in Betaflight. New to FPV? Start with a tiny whoop or a ready-made drone, and only build your first 5-inch once you understand the components.

Build it yourself or buy ready-made (BNF)?

A BNF drone (bind-and-fly) is ready to fly: bind it to your radio and go. Building one yourself takes more time, but teaches you how everything works, lets you choose exactly what you want and enables you to make every repair yourself later.

Our advice: first fly a tiny whoop or a complete kit, then build your first quad once you know the components. You will also understand what you are buying.

All the components at a glance

A standard FPV build consists of these components:

Frame — the base, usually 5-inch for freestyle or smaller for micros and cinewhoops.
Motors — four brushless motors selected by stator size and KV.
Flight controller + ESC (stack) — the brain and motor control system.
FPV camera — analog or digital.
VTX (video transmitter) + antenna — sends the image to your goggles.
Receiver — usually ELRS, for the control link.
Propellers — matched to your frame size.
Batteries + charger, plus a radio and goggles.

Tools you will need

A soldering station and good solder — most of the build involves soldering.
A set of hex drivers (usually 1.5, 2.0 and 2.5 mm).
A smoke stopper for safely testing the first power-up.
Double-sided tape, cable ties and battery straps to secure everything.
A PC with Betaflight Configurator for setting everything up.

The build sequence in brief

Fit the motors to the frame.
Install the stack (FC/ESC) and solder the motor wires.
Solder the receiver, VTX and camera to the flight controller.
Secure the antenna — never power a VTX without an antenna.
Check your wiring with a smoke stopper before connecting a battery.
Remove the propellers and configure the drone with Betaflight.

Setting up Betaflight

Use Betaflight to flash the firmware, configure the ELRS receiver, assign arming to a switch and check the motors’ direction of rotation. The golden rule: keep the propellers off while configuring and testing.

Common beginner mistakes

Cold solder joints — practice on an old circuit board first.
Powering a VTX without an antenna (which can burn it out).
Leaving the propellers on the drone during configuration.
Not using a smoke stopper during the first power-up.
Incorrect motor direction — check this in Betaflight.
Different ELRS settings (binding phrases) on the receiver and radio — see the ELRS guide.

Frequently asked questions

What do I need to build an FPV drone?

A frame, four motors, a stack (flight controller + ESC), an FPV camera, a VTX, a receiver and propellers — plus a radio, goggles, batteries and a charger.

Do I need to know how to solder to build a drone?

Yes, basic soldering is part of the job. With a decent soldering station and some practice on an old circuit board, anyone can learn it.

Is building a drone cheaper than buying one ready-made?

Not necessarily, but you learn how everything works and can make every repair yourself later. Start with a BNF drone or whoop, then build one.

Which receiver should I use?

Usually 2.4GHz ELRS. Make sure the receiver has the same binding phrase as your radio. See the ELRS guide for setup instructions.

Why does my VTX get hot or fail?

Almost always because it was powered without an antenna. Always connect the antenna before supplying power to a VTX.

How do I configure a self-built drone?

Use Betaflight Configurator to flash firmware, configure the receiver and modes, and check motor direction. Always do this with the propellers removed.
