Spydie

Hi everyone, I'm new to the forums and have recently gotten into quadcopters. I have one in the proses of being build and was looking at getting a controller for it. I already have a turnigy 9x that will be used for it but I also wanted to build a transmitter. I saw that someone used an old ps2 controller and modded it to be a transmitter. I plan on following the directions from his article but was wondering if anyone else had any tips for this build. Thanks everyone
