Build A Quadcopter

A Guide to Build Your Own Quadcopter

It is a well-known fact that human beings cannot fly because of their dense bones and flapping their arms does not give them the adequate lift needed to overcome the strong pull of gravity.  Fortunately, there is technology to provide the much-needed flying experience. Building quadcopters is a good way by which people can get their flying experience and have some fun while they are at it.

A quadcopter is undoubtedly one of the most popular crafts in the entire multi-rotor family. It is a bit challenging to build and tends to be relatively costly as well.

GUIDE

The following is a comprehensive guide on how a person can easily build his or her quadcopter:

Step 1: Use

It is important that an individual decides what kind of purpose they want to use the quadcopter for example; photography or recreation purposes or even both.

Step 2: Materials

Quadcopter Materials

Weight is the major concern about materials. If people decide to have light weight material, then they should go with the box method that allows them to build the quadcopter’s arm from a box. This method will also enable them to run wires back into the pipe so that they leave fewer wires exposed.

This step also requires people to select the type of prop and motor system they would like to use. They should strive to get medium-sized props as they have balance in many aspects.

They should source electronic speed controls (ESC) to control the motors. They will connect ESC to both the motor and battery so as to control them via the R/C transmitter.

The quadcopter should be powered using LiPo batteries and a 5000mAh 11.1 volt 3 cell battery is adequate to give them a flight time of 30 minutes.

Powering the motors will need them to make a power distribution board which allows a single battery to power each of the four motors at a go.

The next mini-step requires the person building the quadcopter to choose a transmitter and its receiver. He or she will require a minimum of four channels i.e. roll, pitch, yaw and throttle for the multi-rotor system.

The last material they will need is the microprocessing board which controls all actions of the quadcopter. The 3D Robotics Arduino based microcontroller with RC plane shield is a choice to consider as it will allow them to modify it to their needs.

Materials are listed below:

  • Red and black wires.
  • 2 sheets of 1/4in acrylic.
  • 4 sheets of 1/2in acrylic.
  • 1x LiPo battery 5000mAh, 11.1 volts.
  • 1x 9ch turning RC transmitter and receiver.
  • 4x 20C electronic speed controls.
  • 4x 850 KV brushless motors.
  • 4 x 10×4.7 slow-flyer propellers.
  • 1x PDB power distribution board.
  • 1x ArduPilot Mega from 3DRobotics.

Step 3: Frame Design

People could use flat arms if the material they chose for the arms were thick. He or she can use a laser cutter to cut out the arms. The things they will need to put at the center are a battery, control board, RC receiver and ESC.

He can use a velcro at the bottom to hold the battery which is attached to the tower. He should then add the autopilot and consequently have 1/8 of clearance in that area. He should then follow this with the PDB before he finishes with the receiver at the top. He can cut out the center using a 1/4 inch black acrylic.

He should first add the motor mount and determine where the screws will be put to avoid rattling of the motor. He should measure the arm length using the propeller size, and he should start from the center of the quadcopter. He should ensure to leave out some space when he is attaching the arms to the center of the quadcopter.

Quadcopter Electronics

Step 4: Electronics

He should start by soldering the ESCs and the motors with banana plugs. He should follow this with making the PDB. He should use one plug for the battery while the rest of the 4 for every ESC.

Step 5: Assembly

He can first quickly assemble the frame so as to determine if every electronic fit inside the frame then afterward he can add on each one of the motors to gauge the manner by which they lift. He can then attach the motors to the ESC before attaching the ESC itself. He can add the props last.

The above insightful information clearly shows how to build and customize your quadcopter. Follow the guide and build yours today.
