Rewarding engine build
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.

Fun Engine to Build
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.

Another good purchase
Was hesitant at first due to no rating or reviews at the time I purchased. Went ahead and purchased due to having many models from this company. Project looks good and works great. I only had one piece that was melted/deformed. Luckily I had part in my spare part pile. So didn't have to wait for part to come in. Instructions were not bad at all. Some sections did take time and I would say a bit difficult and annoying too attach. Otherwise went together fairly quick.

Good value
Took a while to put together. Some instructions aren't real clear. Once together it's great. Actually runs. Good price.
