Quad Copter From Scratch





Introduction: Quad Copter From Scratch

The desired output expected from making this instructables was to
make a low cost quad copter from easily available materials. I spent only 3$ for the completion of this project. But I couldn’t accomplish the main characteristics of any drone, that is it won’t fly due to inefficiency of motor (I used dc toy motors). Note that It is not a working model and I have not included any control circuit .The main aim was to make a cheap quad copter .The design of frame and propeller for this project is explained in the description.

Step 1: Materials Used:

1. Plastic ball(2 cm radius)
2. Styrofoam

3. Dc toy motor-4

4. Aluminum can (from spray bottles)

5. Used pen(It used to insert the propeller into motor)

6. Glue gun

7. Wires

8. A battery eliminator to vary the power supply

Step 2: Design of Frame:

The arms of quad copter are made as per the following dimension.

The Styrofoam piece is cut as per the dimension given

By using glue gun fix the prepared arms to the plastic ball

Step 3: Fixing Motors:

Fix dc motors to the edges of quad copter arms as per the image

Step 4: Connection Diagram:

Connect it as per the following image

Note that opposite arm should rotate in same direction .For example
here in my case 2 and 4 motor rotate in counter clock wise direction and 1 and 3 motor rotates in clock wise direction to balance the weight.

Step 5: Design of Propeller:

As main objective is to make a cheap quad copter, I made propeller
also from scratch, note that the design is not effective .

I have used aluminium can, Styrofoam pieces and a pen to build a

Keep aluminium can in between 2 Styrofoam piece and stick it with
glue gun .fix cut piece of pin to the down part using glue gun.so you can insert it into motor easily.my proto type model is given below.

Step 6: Final Assembly:

For your reference I have added video link below

    are you a sri lankan

    no , I am indian ,from kerala

    have small motors it will fly

    I try it

    thanks for introductions

    no .it can't fly as per my design

    So i am trying to overcome the mistakes which i made

    if u use bigger propellers and use alcaline batteries it is surely gonna fly.....

    Thanks for suggestions megamindkaamil

    Hey Amal;

    Just wanted to say that you've got a really cool idea going here, trying to make as much as possible of a complex machine. I've been flying racing drones for a few years, and having built my own, noticed a few things you might want to address;

    - Motor strength: I think your conclusion that the motors are too weak is correct. Most drones above a prop size of 2-3" use brushless motors, simply because of the higher RPM's and low weight. You might want to try using smaller motors, props, and frame, or switching to brushless motors.

    - Props: Valiant effort on those props, but I think they might benefit from some changes. I can't quite tell exactly what they're constructed out of, but you might want to try heating and forming plastic, or something more rigid.

    - Frame: I noticed in the video your frame wasn't quite a perfect X or + shape. You might want to try using just two pieces for the arms and interlocking them in the centre to add some stiffness and keep the shape bang on.

    I really like the concept you've got going here, and I think your design of a wired drone is totally possible. Keep it up!

    Thank you FracturedCrystal
