I received my new K-28 and am very pleased with it. It is serial number 146 of the second batch and it runs equally well in both directions right out of the box. I plan to install R/C and modify the suspension the way Llyn Rice did. Here is a video of the nearly hour long run pulling 5 Jackson and Sharp cars with newly installed ball bearing wheel kits from Phil's Narrow Gauge. Installation was an easy task and greatly improves rolling.
