The first Time 4 Machine I built was the Steamliner. I found the instructions a bit sparse and difficult to follow. This model (Heavenly Hercules) was purchased over a year later and I like the instructions better. They actually start off by showing/tell you how to make turns and what that symbol means etc. As for the model itself it's a lot of interlocking gears so be careful when assembling moving parts. I haven't finished the assembly yet, but everything works. Nice. ;-)
