Package have arrived. I connected front car directly to transformer and put it in the air - without load and friction from rails. I gave it a little juice and it works! No strange sounds etc. Now I must check if it works on rails with proper load.
A work around is placing the set in a 'custom list'. The are found under 'My LEGO' in the menu. These lists for parts and sets are aside from your Parts Lists and Sets Lists, and don't 'count' in your collection. You can also make these custom list public, so you can share them with someone else.
Right now it's possible to exclude a set list from build calculations, but it would be great to have a second option to exclude the list from all statistics. It would be almost like the list didn't exist. This way it would be possible to create list of sets that someone doesn't own, but would like to build or purchase.
The checkbox could be displayed in the "Edit List Details" section:
[X] Include these Sets in Statistics
It would be checked by default for all lists, just like the " Use these Sets in Build calculations" checkbox.
it can handle 12V it's a 12V engine. it suppose to run at that voltage. besides it depends how you plug it in. if you do it with the same setup as the rail it will be regulated with the power regulator, the other outages is direct, ie if you have the one that allow you to extend with button kits to the left. which fit the time period.
as long as you don't mix in any 4,5V parts or engine you will be fine.Those are the ones kids fry due to their lack of electronic knowledge.
