More info at http://www.rcgrabbag.com. After a lengthy and complicated DCC conversion, lighting installation, and drivetrain teardown and lube, I finally get to take the Big Blow out for a lap on the Logan Southern MRR club layout. I'm using a QSI Titan decoder that has stereo sound, so I was able to put the diesel engine sound exclusively on a speaker in the lead unit, and put the turbine sound exclusively on a speaker in the middle turbine unit. In this video, the loco is initially running on it's diesel engine only as it maneuvers around the yard to link up to its consist. Once coupled to its consist, the turbine is fired up and she moves out. I still have a bit of work to do. I need to work on speed matching the lead and center units, and perhaps some bullfrog snot to improve pulling power. I would have liked to run the consist faster, but the B unit speed curve was much steeper than the A unit so when throttling up, the B unit's wheels started spinning much faster than the A unit, so top speed was limited. Oh well, it's only the first run, so I hope to have another video with more "highball" speeds.
