I now have a 5 amp PnP ESC for all bigger AristoCraft and Bachmann locos. The new item is # ECL-PnP5 and, as with other RCS - BELTROL ESC’s, it is designed for use with the low cost 5/6 channel 2.4 GHz radios. Uses constant voltage Track power or Battery power.
Details are available here: http://www.beltrol-rc.com/content/1163/eclipse-esc's/ Please note the PnP adaptor pcb (bottom right in pci) is a working prototype only.
