Amazing model. Got it built in 3 days, working on it about 5-6 hours each day. Runs smoothly and looks great. Instructions were very clear and easy to follow.

Very large engine build. A lot of detail from crank shaft to cams, valves and timing chains. Realistic appearance. Interesting speed gearbox. This was challenging and instructions are good. Some parts need glue to hold in place.
