Take flight with the Erector by Meccano Discovery Helicopter! This STEAM building kit is perfect for the first-time builder. With redesigned parts and tools, it's easier than ever before for kids to build their creations! Kids can snap nuts onto parts to make them lock; and use the bolts to hold pieces together and stay in place as they build. As your young inventor assembles their very own Helicopter model, they'll learn how principles from science, technology, engineering, arts and math are practically applied. Your child can customize their build with the included stickers, then attach the finishing pieces to give their Helicopter a realistic look! Build all of the Erector by Meccano Discovery sets, including a Motorbike, Race Car and Skid Steer (each sold separately). With Erector by Meccano, the building possibilities are endless. Enter the exciting world of engineering with the Erector by Meccano Discovery Helicopter!
