LEGO® Technic Twin-rotor Helicopter 42020. 4.4 5 11 11
Good for special parts I wasn't really planning to get this set. I just happened to go to ToysRUS with my son and then decided to get something simple. I first considered a few other sets but in the end went with this one because I wanted a few parts in this set that my son could use in other projects. Like the blades and the bevel gears. In many of the advanced models I built, I am quite used to the bevel gears and the U-shaped part to put the gears at right-angles. Having two of those available in this set makes this set good for gathering such parts. Of course, it's fun for kids to rotate the knob at the back and see two blades rotating simultaneously. Note: For a 6 to 8 yr old kid this set will be easy to average even though I gave "very easy" rating from my point of view. 03 August 2015

Technic on the rise This set is great! I loved it, except for a few minor accuracy details. I love lego, and am fascinated with helicopters and flying them. When I purchased the set, I was amazed at the level of accuracy for the size. Pros: great functionality and compactibility Cons: The rear wheels stick out too much and so do the side beams. Overall, it is very functional and cute; great for the price. 18 May 2015
So good I bought THREE! Lots of fun with this helicopter. Instructions really good though the younger ones tended to make things "left-handed". They enjoyed building and twirling the rotors. Great! 21 April 2015
