My great nephew is in 1st grade. He seems to really like Lego planes and helicopters. I bought him this for a relatively low price. He tried to build it on the spot (had to force him to stop to eat dinner). He followed the visual instructions and put it together in about 40 minutes. Played with it for quite some time, before he decided to play a videogame. When it was time to go home, he asked if he could take the plane with him. Seems like a hit to me!
