ScoutUAV: an APM-powered quadcopter with a GREAT buildlog

Hack-a-day has a good write-up of ScoutUAV, a custom-built quadcopter using the APM hardware and ArduPirates code. It really is a terrific site and introduction to building an APM-powered quad:

 

DIY-er [Russell] wanted a quadcopter, and like many people out there, he knew the satisfaction that would come from building it himself. Rather than purchase a kit or follow a set of online instructions, he spent a lot of time researching quadcopters, and eventually put together a thorough tutorial himself.

His Arduino-based quadcopter is named Scout and runs about $1,000 to $2,000 depending on which parts you choose to buy. [Russell] has a complete parts list available on his site, including plenty of alternate component choices for builders on a budget.

He covers the construction process in great detail, discussing frame fabrication and component placement as well as how to program the Arduino for the copter’s first flight. He also takes the time to break down his component list item by item to explain how each piece is part of the greater puzzle, which is great for first time builders.

We love seeing this level of detail when discussing a build process, and as you can see by the video embedded below, his quadcopter looks great!

Those are pricey ESCs - I have a few for my planes. But they need to be set up properly to work for a quad. I'm not sure they would be my first choice when you can by 5 Chinese ones for the same price that do work well for quads.

There is no info. about the motors but here it is ;) Rimfire .10

He admitted on his page as well that cheaper option are enough

 

The Rimfire motors are excellent motors but a much cheaper alternative is the Turnigy 2213.  The Turnigy 2213 is more than capable.
