1) On a smooth, flat surface the #7 driver on the engineer's side does not touch.2) On a smooth, flat surface the #6 and the #7 driver on the fireman's side do not touch.3) The front tender truck barely touches the rails on a smooth flat surface, and it derails when going through curves - especially with cars hooked up behind it. (See attached photo). I recommend more weight at the front of the tender, or maybe add a spring to the truck so that there is more downward force on it.4) the motor seems noisier to me than our other n scale steam engines. It makes a sound like there is something rubbing the flywheel lightly. Overall this is a good sample. It runs pretty smooth, it is a good puller, the volume is adequate. Whistle sound is not super- clear. I wonder if that will improve with the use of the final tooled parts. The reverse light is on all the time regardless of F0 being toggled on/off and regardless of direction. This is because the model is programmed with old software - not a factory wiring error. The handrails on the pilot - that detail is very small and fragile. I know the 3d print material is different from the final tooled parts, but should we consider making those handrails brass or wire? The more connection points there are, the more potential breaking points. (See attached photo)
