WARNING!!! All full complete kits have resin casting track plates( by 12 trcks) OMSh type now. But I can change this resin tracks on 3D printed workable tracks as in #418,419 sets. Of course price little highest , it is +$7.1 (RMSh type) or +$9.2 (OMSh type) for regular price. So if you interesting in full kits with workable tracks let me know which type  of tracks you need.
