The **Little Bird Quadcopter** arrives as a box of parts rather than a finished drone, and that is the point. In about half an hour you fit the flight controller, wire in four motors, mount the battery and the FPV camera, pair the transmitter and fly it — and you come away actually knowing what is inside a quadcopter. No soldering and no tools are required. Everything in this guide comes in the one kit. ## How a quadcopter stays in the air Four motors, but not four identical motors. Two spin clockwise and two spin anticlockwise, arranged so that each pair sits on a *diagonal*. If all four turned the same way the whole airframe would spin under its own torque; running them in opposing pairs cancels that out. That is why the kit gives you two motors with **red and blue** cables and two with **black and white** cables, and two propellers marked **A2** and two marked **B2**. The colours and the letters are how you keep the diagonals straight. Every arm on the body is stamped **A** or **B** — that stamp is the thing to trust while you build. Steering comes from varying the four speeds relative to each other: speed all four up and it climbs, slow the two on one side and it rolls that way, unbalance the clockwise pair against the anticlockwise pair and it yaws. The flight controller does that arithmetic hundreds of times a second so you only have to move two sticks. ## What's in the box **Quadcopter** - Quadcopter body - Main flight controller - 4 × motors — 2 with **red and blue** cable, 2 with **black and white** cable - 4 × propellers — 2 marked **A2**, 2 marked **B2** - 4 × spare propellers — 2 × A2, 2 × B2 - Battery and battery compartment - Camera and camera compartment - Double-sided tape - USB charging cable **Transmitter** - Transmitter - 2 × joystick caps - 2 × AA batteries **Optional** - Propeller guards - Steel tool ## You'll also need - A phone (iOS or Android) if you want the live camera feed - A USB port to charge the flight battery before the first flight - Somewhere to fly it — indoors is fine with the propeller guards fitted ## Before you start **Charge the flight battery.** It ships partly charged at best, and a flat pack is the most common reason a freshly built drone won't lift off. **Keep the propellers off until the very end.** The build sequence below deliberately fits them, takes them off for the guards, and refits them last. Anything you do with props on a powered drone, you do near four spinning blades. ## Steps ### Step 1 — Lay the kit out and check it off Empty the box onto a clear bench and sort the parts before you fit anything. Two things are worth separating out now, because mixing them up later costs you the whole build: - The **four motors** split into two pairs by cable colour — two with **red and blue** leads, two with **black and white**. Put each pair together. - The **propellers** are marked **A2** or **B2** on the hub. You get two of each to fly with, plus two of each as spares. Keep the spares in the box. Plug the battery into the USB charging cable while you work through the rest of the build. It takes roughly the time the assembly does, and it means you can fly the moment you finish. ### Step 2 — Fit the flight controller to the body The flight controller is the small **X-shaped board** with four sets of motor leads coming off it. It sits on top of the body, with each of its four arms running out along one arm of the airframe. - Drop it into the recess on the top of the body in the orientation shown. - Press until it is properly seated and flat — it should not rock. - Note which way the battery lead points. That end is the **back** of the drone, and everything from here on is described relative to it. Getting the controller in the right way round now saves you unpicking the motor wiring in two steps' time. ### Step 3 — Drop the four motors into the arms Each arm ends in a round motor slot. Push a motor down into each until it seats fully — it should sit square, with the shaft pointing straight up. **The cable colours decide which motor goes where, and they go in diagonal pairs:** - **Red and blue** motors → front left and back right - **Black and white** motors → front right and back left Each pair must sit on *opposite corners*, never side by side. This is what gives you two motors turning clockwise and two turning anticlockwise, so the airframe doesn't spin under its own torque. If you're unsure, look at the arms rather than the diagram: they are stamped **A** and **B**. Red/blue belongs on the **A** arms, black/white on the **B** arms — and the two A arms are diagonally opposite each other, as are the two B arms. You'll verify this again in the next step. ### Step 4 — Route the cables and plug them into the controller Take up the slack before you connect anything: **wrap each motor cable once around its own arm**, then run it in to the flight controller and push the connector home. That single turn matters more than it looks. It stops loose wire flapping into a spinning propeller, and it keeps the cable from being tugged out of the connector when the drone takes a knock. **Now check your work.** With everything plugged in you should be able to read it off the airframe: - **Red and blue** cables on the arms labelled **A** - **Black and white** cables on the arms labelled **B** If a colour pair has ended up on the wrong letter, unplug and swap it now. A quadcopter with its motor pairs on the wrong diagonals will spin on the spot instead of lifting — and it is far easier to fix here than after the battery and camera are taped on. ### Step 5 — Fit the propellers — A2 to A, B2 to B Each propeller hub is marked **A2** or **B2**, and each arm is marked **A** or **B**. Match the letters: - **A2** propellers onto the two **A** arms - **B2** propellers onto the two **B** arms Push each one straight down onto the motor shaft until it is fully seated and doesn't wobble. A2 and B2 blades are mirror images of one another — one is pitched for clockwise rotation, the other for anticlockwise. Fit one on the wrong arm and that motor pushes *down* instead of up, so the drone tips over on the throttle instead of climbing. The letters are the whole safeguard, so check all four before you move on. They come off again in a couple of steps for the guards, so don't be precious about it. ### Step 6 — Seat the battery in its compartment Slide the battery into the battery compartment and push until it is **fully seated** — it should sit flush, with nothing proud of the housing. The compartment does two jobs: it holds the cell against the frame so it can't shift in flight, and it presents the power lead where the flight controller can reach it. A battery that isn't pushed all the way in will work loose in the air, and a drone that loses power mid-flight simply drops. If you started charging it in step 1, unplug it from USB now. ### Step 7 — Mount the battery onto the body Lower the battery-and-compartment assembly onto the body so it sits over the flight controller. - Line it up so the **battery lead meets the controller's power connector** — the wires should reach without being stretched or pinched under the housing. - Press down until the compartment clips onto the frame. Don't connect the power yet. You'll plug everything in once the camera is on and the guards are fitted, so the motors can't spin while your hands are still in among the propellers. ### Step 8 — Slide the camera into its compartment Slide the camera module into the camera compartment until it seats. Two things to get right: - **The lens faces out of the open end** of the compartment. That end becomes the front of the drone, so a camera fitted backwards gives you a live feed of where you have just been. - **The antenna sits in its channel** in the housing, not folded under the module or trapped against the lens. That short wire is the Wi-Fi link to your phone — squash it and the video feed drops out a few metres from you. ### Step 9 — Tape the camera to the underside of the frame Turn the drone over so you're looking at the bottom of the frame. 1. Stick a piece of the supplied **double-sided tape in the centre** of the underside. 2. Peel the backing off to expose the second adhesive face. 3. Press the camera compartment down onto it, with the **lens pointing forward** — the same direction as the front of the drone. Centre it as carefully as you can. The camera and its housing are a meaningful fraction of the all-up weight of a drone this small, and hanging that mass off to one side makes the flight controller fight a permanent lean. Dead centre flies noticeably better. Press firmly for a few seconds to let the adhesive grab. ### Step 10 — Take the propellers back off Pull all four propellers straight up off their shafts. Lift evenly rather than levering them off at an angle — the blades are thin and the hubs are a firm push-fit. This is not busywork. The propeller guards clip on *around* the motors, and with blades in the way you can't get the guards fully seated without bending something. Off, guards on, blades back on. Keep the four you removed together — you already matched them to their arms in step 5, and you want the same A2 and B2 blades going back to the same places. ### Step 11 — Clip on the propeller guards Fit a guard around each motor, pressing until it is **fully seated** and won't rock or pull off. The guards are listed as optional in the box, and for outdoor flying in open space you can leave them off to save weight. Indoors, or with anyone learning on the sticks, fit them. They turn a collision with a doorframe into a bounce rather than four snapped blades, and they keep the blades away from fingers. Work around all four and check each one is properly home before the props go back on. ### Step 12 — Refit the propellers Push the four propellers back onto their motor shafts, **A2 onto the A arms and B2 onto the B arms**, exactly as in step 5. It's worth reading the letters again rather than trusting your memory — this is the easiest place in the whole build to put a blade back on the wrong corner. Press each one down until it is fully seated, then spin it by hand. It should turn freely without catching the inside of its guard. That's the drone finished. Next, the transmitter. ### Step 13 — Press the joystick caps onto the transmitter The transmitter ships with its two gimbals bare. Push a **joystick cap** onto each one, pressing down firmly until it **clicks** into place. Both caps are identical, so it doesn't matter which goes left or right. Give each a gentle tug afterwards — a cap that isn't clicked home can pull off mid-flight, and you don't want to be hunting for it with the drone in the air. ### Step 14 — Load the transmitter's AA batteries The transmitter runs on the two supplied **AA** cells — it has no rechargeable pack of its own. 1. Turn the transmitter over and **slide the battery cover downward** to expose the slots. 2. Drop both AAs in, matching the **+ and −** markings moulded into the base of each slot. 3. Slide the cover back on until it locks. Check the polarity before you close it up. Get a cell the wrong way round and the transmitter simply won't power on, which is easy to mistake for a pairing fault later. ### Step 15 — Power up and pair Put the drone down on a **flat, level surface** and stand clear of the propellers before you do anything else. 1. **Connect the drone's power leads.** You should see a **flashing red and blue** signal — the flight controller is powered and looking for a transmitter. 2. **Slide the transmitter's power switch up.** It beeps and shows a **flashing red light**. 3. **Wait.** Once the two have found each other, **the lights on both stop flashing** and hold steady. That's your pairing confirmation. Leave the drone still while this happens. It uses these first seconds on a level surface to zero its gyros — pick it up or tilt it mid-pairing and it will fly with a permanent drift to one side. **Still flashing?** Switch both off, check the AA polarity and that the flight battery is charged, then bring them up in the same order — drone first, transmitter second. ### Step 16 — Learn the transmitter controls Take a minute with the control diagram before your first flight — it's much easier to read on the bench than with a drone in the air. The layout is the standard quadcopter arrangement: one stick handles **throttle and yaw** (up/down and rotate on the spot), the other handles **pitch and roll** (forward/back and left/right). The buttons around them cover the extras — takeoff and landing, headless mode, flips and speed rates. The second image is the manufacturer's pairing card, worth keeping if you ever need to re-pair the transmitter to the drone from scratch. For a first flight: guards on, plenty of space, and gentle throttle. Ease it up to about a metre, hover, and get a feel for how it holds position before you try anything else. ### Step 17 — Install the app on your phone The drone flies perfectly well on the transmitter alone. The app is what gets you the **live camera feed**, plus photo and video capture from the air. Scan the QR code for your platform to download it — **iOS** is the first code, **Android** the second. Install it now, while you're still on your normal Wi-Fi. In the next step you'll join the drone's own network, and the drone has no internet connection to download anything over. ### Step 18 — Connect to the drone's Wi-Fi and open the feed The camera doesn't talk to your phone over the transmitter's radio link. It runs **its own Wi-Fi access point**, and your phone joins it like any other network. 1. **Power the drone on.** 2. On your phone, open **Settings → Wi-Fi**. 3. Join the network whose name starts with **"KY4K"**. There's no password. 4. Open the app and press **Start**. You should now have live video from the drone on your phone. Your phone will warn you that this network has **no internet connection** — that's expected, it's just the camera. Tell it to stay connected; if you let the phone drop back to mobile data or your home Wi-Fi, the feed goes with it. **No video?** Confirm you're actually joined to KY4K rather than your usual network, and check the camera's antenna is still sitting in its channel from step 8. That's the build done. Guards on, open space, gentle on the throttle — enjoy it. ## Required Parts (1) | Part | Variant | Qty | Price | Stock | |------|---------|-----|-------|-------| | [Little Bird Quadcopter - DIY drone kit](https://littlebirdelectronics.com.au/products/little-bird-quadcopter-diy-drone-kit.md) | | x1 | $66.95 | In stock | **Required Total:** $66.95 --- ## Finding & Searching Products If a part listed here isn't quite what you need, you can search Little Bird Electronics' full catalogue: - **Search by keyword:** `GET https://littlebirdelectronics.com.au/products.md?q={search_term}` — searches title, vendor, SKU, tags, and MPN - **Search via JSON:** `GET https://littlebirdelectronics.com.au/products.json?q={search_term}` — structured JSON results - **Browse by collection:** `GET https://littlebirdelectronics.com.au/collections/{handle}.json` — products in a specific collection - **Filter in-stock only:** `GET https://littlebirdelectronics.com.au/products.md?q={term}&in_stock=1` - **Individual product detail:** `GET https://littlebirdelectronics.com.au/products/{handle}.md` — full specs, pricing, stock levels, variants Search supports multi-word queries (AND logic).
