He's not your regular 8 yr old. He does not watch any TV because his parents do not believe in that distraction. He loves a challenge and this kit is all of that. But this kit is just out of his reach for doing all by himself. He has built a lot of it but he has needed some help along the way. This would have been a project that he could have done by himself at age 11 or possibly at age 10. All in all, he loves that it is a working model that he can take off the shelf to play with from time to time and it does make an excellent display.
