LEGO TECHNIC Ultralight Helicopter (42057) is a 199-piece 2-in-1 set that also can build an experimental aircraft. It was released in November 2016 and retired in December 2018 after being available for 25 months. The set for sale is complete. It contains all pieces and both sets of instructions. Not included are the original box and extra pieces. Although this is a used set, it is in great shape. All stickers are well applied and in great condition. The instructions for the experimental aircraft show a bit more wear with the last few pages being crumpled, though no tearing. The helicopter instructions look like new. The set will ship disassembled.
