Model Railroad & Slot Car HO Racing Layout: Slot Cars in video: Chevrolet El Camino yellow Auto World Thunderjet vs. Chevelle green Auto World Thunderjet. HO Scale Trains in video: Great Northern EMD SDP40 diesel locomotive engines (Athearn) and eight Great Northern passenger cars (Walthers). The Chevy El Camino is a new self-built Auto World Deluxe Pit kits that had to be painted and assembled (need to touch up more with magnifier). The Chevelle was painted and decorated by Auto World, the El Camino was self-painted. The slot cars worked well with no glitches noted so far and were fun to run around the track, they stayed on the track very well going quite fast in speed on the straightaway tracks. The cars had nice range of speeds on the Parma controllers, so they could be slow through the curves and also sprint on straightaways. We do more like "road rally" than race, like the rally races that go the speed limit and winning is to stay on road, not go off and hit the wall or worse, go on the floor. Video is not at all in order or continuous, with only one camera on tripod that was moved around to various view angles during the race and the clips were edited and intermingled.
