LEGO Technic 42020 Twin-Rotor Helicopter Model Kit

My sister-in-law introduced me to LEGO Technic. Her budding engineer boy started to play with this since he was 5 years old. Technic is a line of LEGO, that is perhaps not so known and not so common, but it is very fun and educational.

Our Little FECS got this for Christmas. These few days have been spent playing with the toys he received for Christmas. This morning, Daddy and him started out with this. It was too difficult for our Little FECS, but he really like this helicopter and was very thrilled that it can rotate as you turn the gear. He had a cozy time building it with Daddy.

It is available from Amazon:
