Is there anyone knows how to build remote controller for quadcopter drone? I wanting to build quadcopter drone with Arduino Uno. Unfortunately, many remote controller for that are expensive in my country. Therefore, i want to build my own remote controller for my drone. It's like Futaba Remote Controller.
Thank you before.. 
Well, you will need some kind of radio. Which one did you have in mind that is available to you?
Hi
Welcome to the forum.
This site looks like a good place to start learning about quadcopters and their controllers, including Arduino based units.
I am not a "drone" user/expert so I hope this is informative as to the gravity of he build.
