The Parts You Need
Your First Parts List
Building a drone from scratch requires specific components that work together. Skip something and it will not fly. Buy incompatible parts and you waste money.
Here is the complete parts list for a basic 450mm quadcopter, perfect for learning the build process before moving to specialized designs.
Frame
The frame is your drone’s skeleton. The F450 is a classic beginner choice, a simple X-shaped design with arms that bolt to a center plate. Expect to pay \$14-30 for a plastic or basic carbon fiber version.
Look for a frame with mounting holes that match your flight controller size. Most F450 variants include nylon standoffs and hardware.
Motors
You need four brushless motors for a quadcopter. The A2212 1000KV is a reliable starter motor at roughly \$7 each (\$28 total).
KV rating tells you how many RPMs the motor spins per volt. A 1000KV motor on a 3S battery (11.1V) spins at roughly 11,100 RPM unloaded. This pairs well with 10-inch propellers on a 450mm frame.
Electronic Speed Controllers (ESCs)
ESCs control motor speed by rapidly switching power on and off. You need one per motor. Thirty-amp ESCs work well for this build at about \$7 each (\$28 total).
Look for ESCs with bullet connectors already attached. Soldering bullet connectors is tedious for beginners.
Flight Controller
The flight controller is the brain, reading sensor data and adjusting motor speeds to keep the drone stable. The Pixhawk (\$25-50) runs ArduPilot or PX4 software and offers GPS integration. The simpler KK2 board (\$15-20) works too but lacks advanced features.
For your first build, start with a basic controller. You can always upgrade later.
Radio System
The FlySky FS-i6 transmitter and receiver bundle costs about \$44. It is not premium gear, but it works reliably for learning. Six channels give you room for basic flight modes plus a few auxiliary switches.
GPS Module
A basic GPS module (\$15-25) enables position hold and return-to-home features. Not required for your first few flights, but highly recommended once you are comfortable with manual control.
Battery and Charger
A 3S 2200mAh LiPo battery (\$20) provides good flight time for this build. You absolutely need a balance charger (\$30-40). Charging LiPo batteries incorrectly causes fires. The IMAX B6 is a popular budget option.
Propellers
10x4.5 propellers (called “1045”) come in pairs of clockwise and counterclockwise. Buy two pairs (\$5-10) so you have four total plus backups.
Spare Parts Budget
Add \$20-30 for spare parts: extra propellers, one spare motor, and some basic hardware. You will thank yourself later.
Quick Check
Q: Why do you need a balance charger specifically for LiPo batteries? A: LiPo batteries have multiple cells that must charge at identical rates. Balance chargers monitor each cell individually to prevent overcharging, which can cause fires.
Q: What does the KV rating on a motor actually tell you? A: KV indicates how many RPMs the motor spins per volt applied. Higher KV means faster spinning but usually less torque, requiring smaller propellers.
Q: Why do you need both clockwise and counterclockwise propellers? A: Adjacent motors spin in opposite directions to cancel out torque and keep the drone stable. Each direction requires a specifically designed propeller.
