Ted S posted:@brianel_k-lineguy I'm curious... have you tested these motors against the originals on straight DC, out of the chassis? I also see a series-parallel switch on the underside. Could it be the RMT electronics do a better job of soaking up the extra voltage, to give lower speeds? I had K-Line's MP-15 and the Kusan-derived FAs. Never bought more because they were just too fast. Would love to know...
I've always run it with the switch in the "Normal Series" mode on our club tracks using a a Lionel ZW-L transformer. It ran smoothly and starts without a jerk. I'm not sure if that's because of that or that gear being worn down. I had it on a "subway" loop on our display layout in the Grapevine Texas Visitors Bureau last year and it probably wore down then. Lots of kids kept pushing the start button.
