Introduction: How to Make a Drone for Under 120$
Hello, This is my instructable: "How to make a drone for under 120$" I'm 13 years old and I wanted to build a drone but I didn't have enough money to buy an rtf (ready to fly) drone that fitted my requirements so I said to my brother let's go build one!
This are the things you need:
1x Transmitter & Receiver
4x Propellers ccw/cw
This are the things that i bought from Ebay and Hobbyking (prices in total):
Motor: Brushless Outrunner a2212 1000kv/13t - 15.12$
Esc: 20Amp Brushless Esc with 3A 5V BEC - 18.12$
Flightcontroller: Openpilot CopterControl3d/CC3D - 10.95$
Transmitter & Receiver: I bought one from internet and it was 30$
>If you don't have one by yourself, buy a 4+channel tx+rx
Frame: Fake F450 Dji frame kit - 15.26$
Propellers ccw/cw: Quanum Carbon Fiber Propeller 10x5 (2pcs) - 12.02$
Battery: 2200mAh 3S 35C Battery T Plug - 13.99$
Step 1: Motors, Esc and Propellers.
When everything arrived, I started to solder the large wires from the ESC to the motor. They all have 3 large wires and they don't have a pattern, you could just solder them randomly. But, 2 of the 4 motors need to be reversed! How to reverse the motors: 2 of the 3 large wires should be reversed and (if everything goes right) 2 of the 4 motors turn the other way around. If you payed attention you saw ccw&cw by your propellers. CCW stands for CounterClockWise, and CW stands for ClockWise. 2 of your motors turn ClockWise and they need CW propellers and the other 2 motors turn CounterClockWise and they need the CCW propellers. On the ESC are 2 more wires and they are black and red these 2 wires are for power. On the frame are some little yellow plates and there need the wires to go. Red= + Black= - You need to solder the wires of the battery to the same board and with the right polarity Black = - Red= + The battery is under the drone and fastened with cable ties.
Step 2: Connecting the Motors, ESC and Propellers to CC3D.
On your ESC are 2 cables, large wires soldered to the motors, and a red/white/black cabble, the cable that we need for this step. These cables are used for signal. this cables need to go in the CC3D, but they have a pattern. In the picture at the top you can see what the pattern is.(The white cable is pointed to the middle of the CC3D.) With your CC3D came an cable that fits in the main port. This cable is for the receiver. Look at the Picture for the pattern.
Step 3: CC3D Setup
We are now almost at the end the only thing you need to do is: the vehicle setup and the transmitter setup.
For those setups we need software: Openpilot GCS (Openpilot Ground Control Station)
You need to download the Openpilot GCS version that supports the CC3D!
The setup is really hard to explain by typing so here is a video! (This video is not by me.)
