Hi Nigel,
Thanks for the detailed reply, I’ve never come across live chassis models before. I’ll order a multimeter, I never thought about that. I have a few questions, if you would be able to help?
How can I tell which way the wheels should go? I can’t see any difference except one side is shinier than the other
Regarding the stay, what’s the difference between the current set up with the metal wire and creating a ring around the motor? Also, I was planning on doing DCC sound. As the current body doesn’t have space, I was thinking of cutting a hole in the bottom of the tender and storing the chip and speaker in there, I have some foam pads to isolate the inside of the tender, but I’m not sure if this will reduce the sound drastically. Would you be able to provide any guidance on this?
