Very well engineered. Nicely detailed, especially in the cockpit and engine. I very much enjoyed painting the detailed pieces and it really came together. I chose the Red Baron color scheme and really enjoyed putting it together. The parts were nicely labeled and fit together very nicely. The parts tree was pretty clean. The only thing that was slightly annoying were the small decals used for instrument indicators - I could not get them to stick to the small parts - even using tweezers - and ended up using tiny amounts of wood glue to get them to stay (when the hadn't fallen apart from trying to get them to stick. Overall a great, good looking model that anyone should enjoy building.
