arduino nano, raspbery pi and wireless xbox controller help

Hi, Im looking for a bit of help with my arduino nano.

My project involves connecting a wireless xbox controller to a raspberry pi using the wireless receiver which I have done. what I want to do is control my RC quadcopter with the xbox controller. So I need to connect my arduino nano to my raspberry pi and output PPM signal from the xbox controller somehow :confused:

I have had a look over the internet through other peoples similar projects but I haven't found anything that relates well to what I want to do

Im new to the arduino but have done a few projects with it some im familiar with how it works etc.

If anyone could help me out, or point me in the right direction that would be great. :slight_smile:
