FPV — Where to start

#fpv/start · Note 1 of 7 · part of Drones

The single most common way to start badly is to buy a drone first. Almost everyone does it, crashes it in the first minute, and spends the next fortnight waiting for a replacement part they don't yet know how to fit.

The order that actually works

1. Buy a radio. Nothing else. A radio is the one item you keep through every other upgrade, and it is the only hardware a simulator needs.
2. Fly a simulator for ten to twenty hours. See FPV — Simulators. This is where you learn orientation and throttle discipline, for free, without repairs.
3. Fly something tiny indoors. A whoop. It cannot hurt you or your walls, and it teaches the difference between a sim and real air.
4. Then a 5". Bought ready-to-fly or built — see FPV — What to buy.

Steps 1 and 2 cost roughly the price of one crashed quad, and save several.

The budget nobody plans for

Beginners budget for the build. The money actually goes on the crash budget: props, arms, a spare stack, the motor you burn out learning that grass eats props. Assume the consumables will match the build cost over the first year, and you will not be unpleasantly surprised.

What the sim will not teach you

Worth saying up front, because it changes what you practise:

• Soldering. Every build begins here. See FPV — The first build.
• Line-of-sight orientation. In goggles you are always looking forward. When a video feed drops you are suddenly flying a dot in the sky.
• Fear. A sim reset costs nothing. Your first real dive over concrete does not feel remotely the same, and that is a skill of its own.
• Failure modes. Voltage sag, a loose motor screw, video breakup at range.

Where the money goes wrong

• Digital goggles before you can hover. They are wonderful and they will still be wonderful in three months.
• A 6S build as a first build. More power, less margin for error.
• Buying a "kit" that omits the charger, the battery bag, or the smoke stopper.

The cheapest flight hours you will ever buy. Twenty hours here is worth more than any component you could spend the same money on.

What you need

A radio connected over USB in joystick / game controller mode. Most modern radios (RadioMaster, Jumper, Radiomaster-clone TX16S family, anything running EdgeTX) do this natively — plug in, pick "USB Joystick" on the radio, done.

You do not need goggles for the sim. A monitor is fine and arguably better while you are learning, because you can glance away.

The simulators worth the disk space

Start with a free one to confirm your radio works and you enjoy it, then buy Velocidrone if you want to get good fastest.

What to actually practise

In rough order. Do not move on until the previous one is boring:

1. Hover in one spot at eye level for sixty seconds. This is the whole game.
2. Figure-of-eight around two points, both directions.
3. Orbits at constant radius and altitude — teaches coordinated roll and yaw.
4. Dives from height, arresting smoothly rather than yanking.
5. Power loops around a gate or a tree.
6. Split-S and Immelmann into a line, so tricks connect instead of standing alone.

The instinct is to practise tricks. The thing that stops you crashing is throttle control, and that is drills 1 to 3.

Honest limits

The sim gives you muscle memory and orientation. It does not give you a feel for prop wash on a real quad, wind, or the way a battery sags at the end of a pack. Expect the first real flights to feel heavier and more urgent than the sim.

In order. Do not skip ahead — each stage is useful on its own, and each one tells you whether you want the next.

Stage 1 — the radio

The only thing you need to start. It outlives every other component.

• RadioMaster Pocket — small, cheap, ELRS built in. Hard to argue with.
• RadioMaster Boxer — full-size gimbals, the sweet spot for most people.
• RadioMaster TX16S — big, colour screen, more than a beginner needs.

Get the ELRS version, not the older protocols. Get hall-effect gimbals if the choice exists. Everything runs EdgeTX, which is the same on all of them.

Stage 2 — goggles

The biggest single decision, and the one most worth delaying until you know you are staying.

• Analogue (e.g. Eachine EV800D, Skyzone): cheap, universal, ugly picture, fails gracefully — it goes static rather than freezing.
• Digital (DJI O4 / Goggles N3, Walksnail, HDZero): dramatically better picture and much more expensive. HDZero fails most gracefully of the three; DJI has the best image; Walksnail sits between.

If the budget is tight, buy analogue and spend the difference on batteries and props. If you already know you love this, buy digital and skip a generation of regret.

Stage 3 — something tiny

A whoop — Meteor75 Pro, Mobula7, or similar. Ducted, sub-30g, safe indoors, and it will teach you more in a week than a month of sim.

Buy it BNF (bind-and-fly) with a receiver matching your radio's protocol.

Stage 4 — a 5"

Either a BNF (iFlight Nazgul, GepRC) or a build — see FPV — The first build.

Buying is not cheating. A BNF gets you flying now, and when you eventually build one you will have a known-good machine to compare against.

The things people forget

These are not optional and they are not in the kit:

• A proper charger — ISDT, ToolkitRC. Not the one in the box.
• A LiPo bag or ammo tin. Batteries fail rarely and spectacularly.
• A smoke stopper. A £5 device that has saved every builder I know from destroying a stack on the first power-up.
• Spare props. More than you think. Then more again.
• A decent soldering iron. See FPV — The first build.
• Batteries — 4 to 6 packs, or you fly for six minutes and drive home.

When not to buy

• Before ten hours of sim time.
• Before you have somewhere legal to fly. Rules are local and they change — check DGCA / Digital Sky yourself if you are in India, and the equivalent elsewhere. This note is not authority.
• 6S as a first setup. Start 4S; the extra power buys nothing you can use yet.
• The cheapest battery on the listing. Sag ruins a flight and hides as "bad tune".

FPV — The first build

#fpv/build · Note 5 of 7 · part of Drones

A 5" freestyle build, which is the standard first build for good reasons: parts are cheap, everything is documented, and it flies well enough to grow into.

The parts list

The tools

• Temperature-controlled soldering iron, 60W+. A pencil iron from a hardware shop will not heat a battery pad and you will spend an hour cold-soldering it. A TS100/TS101 or a Pinecil is inexpensive and correct.
• Leaded solder, 60/40 or 63/37. Lead-free is harder for no benefit here.
• Flux. Not optional. Most bad joints are a flux problem.
• Helping hands, side cutters, hex drivers (1.5/2.0/2.5mm), tweezers.
• Multimeter with a continuity beep.
• Smoke stopper for first power-up.

Order of assembly

Doing this in the wrong order means desoldering things later.

1. Tin everything first — pads on the ESC, wire ends. Never solder untinned.
2. Motors to arms, then route the wires. Cut them to length now, while you can still reach the pads.
3. Motors to ESC. Order does not matter electrically — you fix direction in software later.
4. Capacitor across the battery pads. Low-ESR, 35V, 470–1000µF. It protects everything and cleans up video noise. Do not skip it.
5. XT60 to the battery pads. Get polarity right. Check it twice, then check with the multimeter.
6. Stack in, with the FC on soft mounts if the frame supports it.
7. VTX and camera. Keep the VTX antenna clear of carbon.
8. Receiver, antennas out at 90° to each other.
9. Continuity check. Battery + to − should not beep. If it does, stop.
10. Smoke stopper, then power. Only then, a real battery.

Betaflight, first flight

Order matters here too:

1. Ports — set UART for the receiver and any telemetry.
2. Receiver — protocol, then bind, then confirm all channels move.
3. Modes — arm switch first. Set a failsafe and test it by turning the radio off with props removed.
4. Motors tab, props off. Check direction and order. Fix in software.
5. Rates — start modest, around 600–700°/s, matching your sim (FPV — Simulators).
6. Do not tune anything. Stock Betaflight tunes are genuinely good. FPV — Tuning and flying explains when that stops being true.

The mistakes everyone makes once

• Reversed polarity on the XT60. Instantly fatal to the stack. This is what the smoke stopper is for.
• Cold joints — dull, blobby, and they fail in flight rather than on the bench.
• Unsecured wires near props. A prop finds any loose wire immediately.
• Props on the wrong way. They are marked; the quad will flip and you will blame the tune.
• Arming with props on, indoors, "just to check". Do not.
