Grandson loved it! Legos are great products!
The helicopter is the reason why I bought this set. It's very well designed. The only real gripe is that the helicopter really doesn't need a tail rotor because it uses two main blades to counter act the rotational effect a single main rotor would produce. And again, I still think the base was a afterthought. Not enough pieces to be really good, and yet, if thy left it out, this set would be missing something for the helicopter to attack.
