Help reading analog pins

can't draw it right now..

but it's rather simple.. 1 cable connecting the receiver from 5V, one from GND, and one from it's channel to A2.

The hardware IS capable of accurate values. The problem is with reading the information.
I think it is something related to this RCArduino: How To Read an RC Receiver With A Microcontroller - Part 1

but I would like to find a more simple solution...
