Our roller coaster isn't making as much progress as I would have liked it to be at. We have had some issues with finding where it can change directions and speed but we are working that out right now. Inertia has effect our building process because if we don't get the right amount of turn, then it will fly off straight. It has been frustrating when not everyone in the group is helping out. Our loop has worked every time so we are very proud of that.
