Brilliant Mike, I admire your problem solving mindset. As usual, when faced with a challenge it helps to break down things into smaller parts.
Thanks for another E.T. Lane sketch. Looking across Rising Star, Evening Stare and Gorgon, the lines seem to be getting straighter! And then there is Royal Star, which seems to suggest that once the initial sketches were done, they were developed into something more advanced?
Regarding the wheels, even with radio control, would the printed material slip on rails? Some sort of adhesion needed?
