Read receiver data from Micro MWC board (Atmega328P chip, CYRF69103 Rc)

Hi,
I'm an italian student and for an university project (build an bird robot able to fly stably) I'm using a micro mwc flight controller. On the board I have an CYRF69103 receiver and a ATMEGA328P. This board is used for mini quadcopter and almost always use MultiWii program. I want to read the rc (radio receiver) signal but i don't want to use all the MultiWii program. Does someone know if there is a rc library for arduino that i can use to read directly my signal? Or does someone know a way to read it (the protocol)? It's my first work using arduino and this type of board. Sorry for my english. Thanks a lot.

Luigi
