The circuit diagram for the trasmiter that I have contructed can be downloaded from

Its a very simple, basic and cost effective approach to design a Quadcopter RC trasnmitter. I am using a nRF24L01 radio trasciever as my primary communication design owing to its sophesticated speeds and ease of availability. And also the module can be interface to any microcontroller weasily via SPI protocol.
But you can also try to replicate this with any kinds of transcievers live Xbee, radio transmitters or Wi-Fi modules. Its all about getting ideas and once you get one, you can easily make it work. Also try including more input buttons so as to increse the functionality.
Since I am using an atmega328, I have restrictions when I try to use more inputs. So try the same project with something like a PIC or atMEGA2560 where you are at the libety to expend more input/output ports. The more the pins you have its easier to increase the no.of communication channels.
Suggestions are most welcome and would love to hear it out from you. Thank you.
