Ok thanks. The rats nest of wiring is not daunting to me, I routinely work on radios in my Ham Radio hobby, thus I have the needed tools and safeguards for the boards.
One thing I am still uncertain of is the actual downloading of sound files. Can these be downloaded to Android and then into the DCS control to program the engine or do I need to use an actual computer? I know for some of you this is a dumb question.
