I have started some conversion to fix this problem. We have to cut part of the metal frame to make room for the wheels to turn.
I plan to extend the NEM coupler and make some run test to 50cm radius turns.
I'm also thinking if it would be a good idea to put the NEM holder on the boggies as seen on some older wagons, what do you think?I'll let you know more as soon as there is some progress. Any ideas will be most welcomed
btw. I have received the test print of the decals set, more info and photos will follow shortly
