"Like others have said, the helicopter is not functional. You have to pull the cord very hard. If the helicopter lifts off, it spins out of control and falls to the ground. If it goes up it spins uncontrollably in the air and likely hits something or someone. In NO way does it work as represented in the promotional video - there is NO fine control at all! Because it is one big plastic piece there in no other purpose for the helicopter than collecting dust. The truck is ok at best, not the most elegant design but ok. Even for £20 this set would be average at best. We love Lego, and have many great sets. But this is really exceptionally bad. LEGO, you can do better!"
