Best of the 4, this model really came together well. Videos useless, but carefully reading the manual allowed the building of this model. 5 to 6 hours to complete, definitely one for 14+ y.o. Much fun had after.

I had a great time putting this together. Took me about 5 hours total, sometimes only a 1/2 hour at a setting. The assembly is somewhat episodic so you can work on certain assemblies and then put it down and come back later. The tolerances of the pieces were amazing. Everything (and I mean everything) fit together with a light/medium press fit, no glue required. I am a retired engineer familiar with tool and die tolerances and this assembly was impressive. I’m going to order another one.
