Build

Requirements

Basic skills with wire, RC electronics and soldering.

An mcu and a bunch of sensors that appears on the supported hardware list

Almost ready to flight controller boards aka "Shields"

Some vendors sell almost ready to fly boards. For some the boards you only have to add the sensors you want, like the gyroscope and accelerometer, in others you also have to add a processor board compatible with Arduino.

Ready to flight controler boards

Several vendors sell complete boards with several sensors like gyroscope, accelerometer, magnetometer or barometer. This boards are the more "ready to fly" you can get without using a soldering iron.

Size and Weight consideration

If you play outdoor, your flyng rc model must be resistant to the wind.

• the heavier the better - more momentum and inertia
• the smaller the better - less exposed surface to wind

Also, smaller props with faster (higher Kv) motors will be more wind resistant than bigger props.

Outdoor

A typical outdoor beginner multirotor has 8″ prop and 1100kv motor up to 11″ prop with the 900kv such as this quad. Both combinations can easily lift a payload up to 300g. You’ll have a 10-25 minutes flight time with a lipo battery of 2-3S and 2000-3300mAh depending of the payload.

Indoor

A typical indoor beginner multirotor build with 5" props up to 6"

Micro=

A more advance builder may have an indoor quad with props less than 4".

Firmware

open the Arduino ide and change the file config.h to match your configuration
