mine, which has yet to be painted, wants to short itself out between the trailing (tender) truck and the frame/chassis.
my cure, which I am not at all happy with, but does work, is a piece of scotch tape between the two to act as an insulator.
A good friend of mine, George Pierson, has been twerking this engine of mine for better performance.
Do any of you have experience with this engine and any suggestions to improve it? No need to re-invent the wheel.
