Hello guys,
How are you?
Im new here, Im from Brazil and Im mounting my 4th Lego toy, I finished and everything is mounted by the book, is doing all movements except go backwards and forwards.
Looks like that I dont have enough traction to move truck.
Im attaching photo from bottom, as im new here i dont if is possible to upload a video, but i will try.
thank you so much guys for your attention, as this is my new complex lego, maybe lost a detail.
