"This is a challenging kit. But at least it is built by numbered bags sequentially. It is totally fantastic. The cockpit is detailed and even has a joystick. I would say it took me 10-14 hours to assemble, but I took my time. The only fault with the instructions is on the decals. Lego did not indicate where on the opposing side to put 2 of the decals. But it is easy enough to figure out. I totally love the kit. The wings open and close easily. And so does the cockpit and storage area under the belly. The only thing I am disappointed with is the stand. It is not sturdy enough to hold the model straight since it is back end heavy. Otherwise this is the most detailed and strong kit I have come across. I would highly recommend you trying it!"
