At first you must set your goal from the aircraft industry (and we will call it from now on), do you want to fly for fun? Do you want to carry a camera for aerial photography? Do you want to carry large speakers to address high numbers of high altitude, for example? What you need to think about is that the more your aircraft work, the more equipment you will carry, which means heavier weight, so you will need stronger engines.
There are many different models of airplanes, some of which resemble traditional planes and some like what we see in science fiction movies.
There are many types of prefabricated structures that you can use to design your aircraft. These structures are not for warplanes or even commercial ones. These are the smallest models and have only three arms. Their performance is usually simple and usually flies for short periods.
The so-called Quadcopter, the most popular of the amateur, is fairly powerful, with four engines and four arms, slightly less powerful than its predecessors but much stronger than its basic faults.
A six-speed, six-engine and six-engine engine requires two batteries to operate and carries heavier loads. If a motor stops working, it does not mean the plane is down to the point of losing its ability to steer it. .
Finally, there is an octopter, the "big brother" of those drones, and usually can fly longer times and farther distances, which is the most expensive in terms of construction as well.
There are a number of basic components you will need to build a dron, including the following materials:
Example
These components were used by a British amateur to build a helicopter
You may also need some programming experience to build your aircraft control model:
