Here is a really small quadcopter that uses Arduino and Brushless motors Built by Bob. I will mainly describe the parts and hardware you will need to build this mini quadcopter, and I will not go into flight controller configurations, software and programming etc. There are many options out there. I will do another post about this.
This little Arduino quadcopter is an brilliant design and is runs very quite. Because of its small size, this little quadcopter is perfect for indoor flying.
Here are the parts used to build this mini quadcopter.
- Motors: HK 18-11 2000KV Micro Outrunner (10g) motors
- ESCs: TURNIGY Plush 10amp 9gram Speed Controller
- Battery: 2S Lipo Turnigy Nano-Tech 460mA.
- Radio Control Futaba 7C 2.4 FASST TX and FrSky 4ch/PPM
As for propellers, some cheap 5x3x3 props (2 CW and 2 CCW) are used. The Hobby King 5×3 and 5x3R aren’t very good. They do work, but it takes a long time to balance them, and sometimes the mounting hole is not centered.
Anyway, from the picture you can see it uses Arduino Pro Mini as the flight controller. There are a lot of opensource quadcopter library for Arduino, such as MultiWii. Therefore unlike KK flight controller boards, you will need to equipped your Arduino with IMU. But the good thing about this is, you can add whatever components and modules you want to the Arduino, such as bluetooth, for iPhone / Android control.
