Selection of drone for your interest is very tough when it comes to various and vast drone domain.

Even though we have the luxury of selecting and purchasing one for our need, at what cost is the question. In that aspect how about engineering and designing drone by yourself. This will be led to have all features or many features of a drone to be in top score.
To do this one must have electronic knowledge and embedded development capabilities, but in this article I am here to ease your pain on background for these aspects.
I’m not going to elaborate on these as this will make the article more longer, But as drone enthuses you can search for those on internet.
Balance of force, SUM(Fi) must be equal to m x g
Net aerodynamic torque is based on direction user requests.
Idea is that two control systems—inner controls and outer controls—work against our tendencies to deviate. Control theory can either be classified as centralized or decentralized or neither. Decentralized control is considered as market control.
For example, think of a situation where you are driving a car and you want to maintain speed in a hill. In this case acceleration increases as we climb the hill. This is called feedback control.
(P) Proportional – You are applying proportional control to the car speed.
(D) Derivative - Faster the speed is dropping the more acceleration is applied. (amount of speed drop)
(I) Integral - Control as a constant summation function, constantly adding up the error from the target speed and providing feedback proportional.
Consider above example for our drone, we want to make our drone hover around altitude at 1 meter where it needs to take from ground at higher speed but want to gradually reduce speed at 1-meter height.
The power given to drone motors to control the spin is elaborated.
Consists of physical artifacts of technology designed and offered by the open design movement. Both free and open-source software (FOSS) as well as open-source hardware is created by this open-source culture.
Make sure to have good vibration controllers so that flight controller IMUs (gyros) are secured from the vibration. Following figure compares before and after adding vibration dampers to secure the flight controller board
