Drone building guides
What the parts do, how to pick them and how to put them together — written by the people who pack the boxes. Every guide links straight to the parts it talks about.
FPV basics
What Is FPV? The Full Form, How It Works and How to Start
FPV is short for First Person View — flying a drone through a live video feed from a camera on board, in goggles or on a screen, as if you were sitting in the pilot’s seat. Here is what the term covers, how the video link works and what a first setup looks like.

Drone Parts Explained: Every Component and What It Does
The main parts of a drone are the frame, motors, ESCs (speed controllers), flight controller, propellers, battery and radio receiver — plus, on an FPV drone, a camera and video transmitter. Knowing what each one does, and which spec matters when you pick it, is most of what you need to build, upgrade or repair a drone. Here is the full list, from the frame outward.

Motor KV Explained: What 1000KV, 1750KV and 2207 Actually Mean
Motor KV is how fast a brushless motor spins per volt with no propeller on it: a 1000KV motor turns about 1,000 RPM for every volt, roughly 12,600 RPM on a full 3S pack. Together with the stator size, KV decides which propeller and battery a motor belongs with. Here is how to read a motor listing and match it to a build.

ESC Beep Codes: What the Beeps Mean and How to Calibrate an ESC
ESC beep codes are the tones an ESC plays through the motors. Three rising tones at plug-in mean it has power; a final ready beep means it has found a throttle signal at zero; a beep that keeps repeating usually means no signal, or throttle not at zero. Once you know the sequence, most “my drone just beeps” problems take a minute to diagnose. This guide covers BLHeli_S, BLHeli_32, AM32 and the older SimonK and Hobbywing-style ESCs.

LiPo Battery Guide: 2S, 3S, 4S and 6S, mAh, C Rating, Charging and Storage
A drone LiPo battery is described by three numbers: cell count (S — 3.7 V per cell, so 3S is 11.1 V and 6S is 22.2 V), capacity in mAh, and discharge rating in C. This guide explains those numbers, which pack suits which drone, and the charging and storage habits that keep packs healthy and safe.

Flight Controller Guide: Betaflight vs INAV vs ArduPilot, F4 vs F7 vs H7
The flight controller is the drone’s brain: it reads the gyro a few thousand times a second and tells each motor what to do. Which board you need depends far more on the firmware you plan to run than on the processor letters — here is how to decide.

18650 vs 21700 Li-ion for Drones: Which Cells, Which Packs and Why
18650 and 21700 are Li-ion cell sizes — 18 × 65 mm and 21 × 70 mm. For drones the 21700 usually wins: a Molicel P42A or P45B holds 4200–4500 mAh and delivers up to 45 A, against 2800 mAh for the best high-drain 18650. Li-ion stores more energy per gram than LiPo but gives it up more slowly, which is exactly the trade a long-range or endurance drone wants. This guide compares the two formats, explains the Molicel numbers and shows how a drone pack is built.

Build an F450 Quadcopter: Parts List, Wiring and Real Cost
The F450 is the frame most people in India build their first drone on — a 450 mm plastic-arm quad that flies on 1000KV motors, 10-inch props and a 3S pack, and takes a Pixhawk when you want GPS and autonomous flight. Here is the complete parts list with today’s prices, the wiring, and an honest answer to “how much does a DIY drone cost?”.

Agriculture Drone Parts: What Goes Into a 10–30 L Spraying Drone
An agriculture spraying drone is built from seven groups of parts: a heavy-lift frame with a 10–30 L tank, one motor–ESC–propeller set per arm, 12S or 14S batteries, an autopilot that flies the field on its own, a smart radio, the spray system and its sensors. This guide walks the build in that order — what each part does, the numbers that must agree, and what it costs in India.

Camera Drone Buying Guide for India: The 250 g Rule, Specs and Budgets
Buying a camera drone in India starts with one number — 250 g — and then a short list of specs that separate footage you can use from footage you delete. This guide covers the rules, the specs, the budget bands and the Indian-made options.

FPV Drone Motors: How to Choose Stator Size, KV, Voltage and Mount for Any Build
The right FPV motor is decided by the frame and prop, then the battery: a 5″ quad wants a 2207 or 2306 at 1,750–2,050KV on 6S, a 7″ long-range quad a 2807 at 1,300KV, a 65 mm whoop an 0702 at 19,000KV or more. This guide gives the full table by build class, explains the voltage and mount rules that stop a motor fitting, and how to replace a single motor without upsetting the other three.

Heavy-Lift Drone Motors: Thrust per Arm, KV, Voltage and Props for Big Payloads
A heavy-lift drone motor is chosen from the aircraft’s all-up weight: total maximum thrust at least twice the weight, divided by the number of arms, read off the maker’s thrust table at your voltage and prop. This guide gives the motor classes from a 1 kg F450 to a 100 kg-payload octocopter, the voltage and ESC families that go with each, and the props and frames to match.

4-in-1 ESC Guide: Amp Ratings, 20×20 vs 30×30, Voltage and Firmware
A 4-in-1 ESC is four speed controllers on one board under the flight controller. Pick it from the motors’ maximum current with margin — 45–65 A for a 5″ freestyle quad, 55–80 A for 7″ and 8S — then the voltage rating, the mounting size that matches your frame and FC, and a firmware that supports bidirectional DShot. This guide covers each decision and the small things (capacitor, pinout, direction) that burn boards.

AIO Flight Controllers: Whoop, Toothpick and 5-Inch All-in-One Boards Explained
An AIO flight controller puts the gyro, processor and a 4-in-1 ESC on one board — and on whoops, the ELRS receiver and video transmitter too. It is the lightest and cheapest way to build anything under 250 g, and a fair choice on a 5″ freestyle quad if you accept that one burnt ESC channel takes the whole board. This guide sorts the boards into three classes and lists what to check before buying.

Whoop and Micro Prop Sizes: 31 mm, 35 mm, 40 mm, 45 mm, 65 mm and Shaft Fit
Whoop props are named by diameter — 31 mm for a 65 mm frame, 40 mm for a 75 mm frame, 45 mm for an 80 mm frame, 2″ to 3.5″ for toothpicks and cinewhoops — and the second thing that decides whether one fits is the motor shaft: 0.8 mm, 1 mm, 1.5 mm, T-mount or M5. This guide maps size to frame, motor and shaft, and explains blade count, pitch and ducted props.

FPV Radio Controller Guide: ELRS vs Crossfire vs FlySky, Gimbals, Module Bays and Range
Choose the radio link before the handset: in 2026 that is ExpressLRS for almost every FPV build, with Crossfire, FrSky, FlySky, Radiolink, Skydroid and mLRS each owning a niche. Then pick the form factor — full-size, compact or pocket — hall gimbals, and a module bay if you will ever add 900 MHz. This guide walks the choices and the receiver rules that follow from them.

LiPo Charger Guide: Watts, Amps, Parallel Charging and Safe Charging for Drone Batteries
A charger is sized by watts: amps at the 1C rate times the pack’s full voltage, so a 6S 1300 mAh pack needs 33 W and four of them on a parallel board need 131 W, while a 12S agri pack needs 800 W. This guide runs the numbers for every pack size, sorts AC, DC and dual-channel chargers, covers the chemistry settings that must be right, and the parallel-charging and safety rules.
