Granted, operations on a two-foot wide module is limited, but not impossible. So, here is a video of me moving my S-Helper Service NW2 back and forth on one of the tracks of the module. You'll hear the clicking of the change-of-direction of the throttle. This is a battery-powered engine, so no wiring used. It is difficult to hold the cellphone and the throttle at the same time, while making sure that the engine doesn't run off of the ends of the module. So, while not great, it is something. Lighting isn't great either. I hope to eventually be able to take better quality videos.
