FPV

FPV System Setup Introduction

If you’re a reader who has experience flying RC airplanes, or who has read about the basics of RC flying, this article will help you get started in setting up your first FPV system.

Propellers

 Propellers

These things are evil and will hurt you if you don't take care. So make sure to never go near a rotating propeller with any body part you want to keep.

Motor

Motors

As you can imagine the motors are one of the more important elements of a multirotor, because - well - they are an the only parts that keep it in the air. Since it doesn't have a wing, you have no surface to glide after all...

Battery

Batteries / Chargers

There is a whole section on this forum on batteries and charging systems, so there is no need to go in detail here.

ESC

Electronic Speed Controllers (ESCs)

The electronic speed controllers (ESCs) drive the motors based on input of the controller. There are different types of ESCs for different types of motors. Brushless motors (also called outrunners or inrunners) are used for multirotors and require an ESC that works with brushless motors.

Flight Controller

Controllers

The controller is the brain of a multirotor. It takes input from the receiver and tells the speed controllers to translate that input into movement. The difficult part of its job is to keep the copter stable. To do that it needs all kinds of sensors to learn about its orientation and position.

Frame

Frame

The Chassis is the basic structure of a multirotor where all other parts are connected to. Think of it as two parts: a "core" and the "arms" where the rotors are attached. The core houses most of the electronics and protects it from crashes. Also you usually find the center of gravity there.

MultiWii Beginner

Multiwii Beginners Guide 

This document is to provide the Beginner with some basic guidance to some of the most common problems related to configuring the MWC. It is not intended to be a cure all and nothing stated within this document is legally binding.

MultiWii config.h

How it works

The first configuration of MultiWii is done in the config.h file of the firmware source. With a programming IDE like Arduino or a simple text editor, you can change several options for your multicopter, flying wing or helicopter. This is done by adding or removing of the // in front of the #define parameters which comment or uncomment the line so it is included or not in the final firmware.

Transmitter

Transmitters / Receivers

To be able to control your multirotor, you need a remote control (RC) link. The link is established between a - usually hand held - transmitter and a receiver in the multicopter.
