The retrofit project actually led to design of an under-floor powered truck needed to clear the passenger compartment for something other than a motor. That's how I linked up with David Rygmyr after he purchased Northwest Short Lines (NWSL). Dave was receptive to replacing NWSL's venerable PDT ("pretty darn tiny") powered truck, which is how Stanton Drive became an NWSL product.
Peter Berg, owner of Berg's Hobbies, who had seen my battery power and radio control ideas prototyped in his Sydney Suburban models, encouraged me to "productize" the home-grown radio throttle. He liked its simplicity from a user perspective and suggested I repackage it into something more marketable. So began S-CAB.
