After seeing so many amazing FPV video's on youtube I really wanted to learn how to fly FPV and create some videos of my own. I looked over a lot of very helpful websites and was able to gather lots of good information to succesfully complete my first 250 quad build. This instructable is my effort to create sort of a one stop guide from a pile of parts to taking flight. I will cover the required parts, assembly (wiring soldering, ect...), flight controller programming, and offer a few practice suggestions. Thanks!

Step 1: Create the XT60 Battery Lead
Using 7" of 16AWG wire, solder the red and black wires to the backside of the female XT60 connector. Add heat shrink over the metal connectors on the back side of the XT60 connector.

Step 2: Solder XT60 Lead to the Power Distribution Board (PDB)
First, you'll notice I am not using the PDB that came with the frame. No good reason for this other than I already had purchased the PDB pictured and used it because the female bullet connectors came pre soldered. Before you solder the leads to the PDB don't forget to add the heat shrink to the wires.

Step 3: Mount the Power Distribution Board (PDB) to the Quad Frame
Use x2 plastics standoffs and attach to apposite sides of the PDB. The plastic standoff will be used to mount the flight controller to in a later step. Use x2 screws to attach the power distribution board to the frame.

Step 4: Solder Male Bullet Tip to Motor Leads
The motors I used came with the bullet connectors.

Step 5: Mount Motor to Frame Arms

Use the screws supplied with the DYS motors.

Step 6: Connect ESC to Motor Leads
You will have 3 wires coming from the motor that will all be black. Connect the bullet connecters from the black motor leads in to the ESC female bullet connectors (the order doesn't matter at this point).

Step 7: Connect ESC Power Leads to PDB

Plug the black and red male bullet connectors on the ESC in to the black and red female bullet connectors on the PDB.

Step 8: Repeat Steps 4 Through 7 for the Remaining 3 Motors and ESC's

Step 9: Mount Flight Controller
Take note of the arrow on the bottom of the flight controller. The arrow needs to point to the front of the quad. Place the flight controller on top of the plastic standouts and secure with screws.

Step 10: Plug PWM Wire Harness to Flight Controller and ESC's
Plug the wire harness in to the flight controller and connect the ESC's to the wire harness in the following order:
PWM 1 - Right Rear
PWM 2 - Right Front
PWM 3 - Left Rear
PWM 4 - Left Front

Step 11: Connect Battery to Make Sure There Is Power to the Flight Controller
WARNING! Please remove all props from the motors!
We can now connect a 3s or 4s LiPO to see if all of our connections are working. The ESC's and flight controller should flash red and then stay solid green. You will also hear and audible tone come from the ESC's. The ESC's have 5v UBEC's built in so the voltage coming in from the battery will be stepped down to 5v.

Step 12: Connect RC Wire Harness to Receiver
Connect the RC wire harness in to the receiver in the following order:
The values below on the left are listed on the reciever and the the channel numbers are marked on the wire harness connectors.
ELEV - CH2
AILE - CH1
THRO - CH3
RUDD - CH4
GEAR - CH5
AUX - CH6

Step 13: Mount Receiver to Quad Frame and Connect the Wire Harness to the Flight Controller
Find a good spot to mount the receiver. You want the receiver to survive in the event of a crash and there will be lots of crashing. I used 3M double sided foam tape to secure the receiver to the rear of the quad. The RC wire harness connect to the side of the flight controller. The plugs on the flight controller for the wire harness' are all different sized so there is no risk of plugging to the wrong port on the flight controller.

Step 14: Bind the Transmitter and Receiver


I was able to bind the transmitter and receiver by just power both on and moving the throttle up for a brief second and then back down to 0. Once binded the receiver will show a solid red light. I have attached the Devo 7 user manual in case you run in to any issues.

Here is ur answer:
Quadcopter can achieve vertical flight in a stable manner and be used to monitor or collect data in a specific region such as mapping terrains. Technological advances have reduced the cost and increase the performance of the low power microcontrollers that allowed the general public to develop their own Quadcopter. The goal of this project is to build, modify, and make improvements in Quadcopter design to obtain stable flight, gather and store CO2 data. The project used a Quadcopter that included a frame, motors, electronic speed controllers, Arduino development board, and sensor boards. Batteries, a transmitter, a receiver, a GPS module, and Sim card were interfaced with the Quadcopter’s frame. Individual components were tested and verified to work properly. Calibration and tuning of the PID controller was done to obtain proper stabilization on each axis using custom PID test benches. Currently, the Quadcopter can properly stabilize itself, determine its location. This report also described the auto-commands, and live video streaming that can be implementing at a later stage. Most of the goals in this project have been achieved, resulting in a stable and maneuverable Quadcopter. The aim of this project was to build and program a Quadcopter that can be used to collect Co2 information of a surrounding area. A secondary goal of this project is to use this platform for future innovative projects that could include stabilization, image processing and artificialintelligence.
