Controlling your R/C transmitter from a PC using an Arduino

Hello,

Here is a project i am trying to build:

https://www.min.at/prinz/?x=entry:entry130721-182227

The problem is that i understand Arduino scripting only at a very basic level.

My question is:

Should i upload the protocol code with all the hex addresses in it as is to the Arduino or is it only a protocol general description, from which one is supposed to build the Arduino code itself?

Since i only understand simple Arduino scripts and know almost nothing about hex addresses (besides the way they look)…is it complicated to build the Arduino code itself, from that protocol description? How should that be done?

Thanks.
