Intro to FPV RSS
So just what is a racing drone and what makes it work? To get a quad in the air you need seven things. To make it FPV you need a few more. Let's go through them one by one.
Propellers make a big impact on how a miniquad performs & how long a battery lasts. In this post, we explain what all the numbers means and what props you should choose.
The flight controller (or FC or sometimes even just “board”) is the brain of the quad. It carries the sensors and processor that make all this possible. Using data from a gyro and an accelerometer (just like the ones in your smartphone) along with input from the radio control link it knows what the quad is actually doing and compares it to what it should be doing.
Put simply, ESCs (or Electronic Speed Controllers) take signals from the flight controller and current from the battery and tell the motors what to do.
