This is one of the best small Technic sets I've seen in recent years, and the only one I've bought; I usually buy the larger sets but this set has better value for money than usual for a small set, maybe because the wheels are small. The set has 3 functions: - Twin rotors that rotate in opposite directions like a Chinook helicopter and are actuated from the rear. These spin well as long as you make sure the parts rotate freely as you build. - Swivelling front wheels for taxiing. - Opening rear cargo ramp. Pros: - Good parts for small aircraft models. - Very swooshable! - Small enough to be swooshed during a long car journey. - 4 wheels are provided so a car could be built from the parts. - This is a good set to buy in multiple if you need the the rotor blades, the gear brackets or the small wheels, which are very useful for guiding sliding things (see crane 42009). - More experienced builders can move on to the Cargo Plane 42025. I added the rotors from 42020 to my Cargo Plane to give it more-realistic 6-blade propellers. - Good value for money as small Technic sets go. Possible improvements: - The instructions did not advise any particular orientation of the two rotors relative to each other. This may be because they are at different heights and do not bend in the model, so they would not clash. On a real Chinook the rotor orientation is critical to keeping the blades apart; a gearbox failure could lead to a blade clash and loss of the aircraft. The set opens up opportunities like this to learn more about aircraft, making it an ideal accompaniment to a flight or an aircraft museum visit. - The rotor parts have good grip on the hub piece but there would be a limit to rotational speed if such a rotor were motorised in your own models. When I was young I used to put wheels or propellers on a motor and rev it up as fast as possible! This raises the opportunity to learn about robust rotor construction. In this case a 3-lobe piece like design ID 32125 could stop the blades detaching at high speed. This is an ideal introduction to the Technic theme for young engineers. Since some Technic sets used to start at 6 years old, perhaps a talented child younger than 7 could build it with supervision.

Ok product

Bought for my 10 yr old and he thought it was going to be bigger. He still likes it though.

                    The twin-rotor of helicopter is very good.
                    I recommend this for gift.

                      great toy, it offers 2 possible ways to build the helicopter and my son of course being a LEGO expert as he is came up with additional parts and ways to build it, so it's actually more then 2 options and he just loves it!

                      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.

                        My 1st helicopter Lego set, so I have been really excited to play with this one. All in all, a lot of simple technical elements, so it's a good teaching tool for kids, or for older collectors that want to learn basic physics principles. Fun elements with rotors and gears, and is combinable with other Lego sets for larger builds, as the Technic sets work with other Lego sets to give them more motion and funtionality. Additions I'd like to see for this set are support for the power functions as are available in larger Technic sets. Would be cool to have a small engine connected to the rotor gears, as well as an on/off switch for more playability. Also, would be sweet if there were another small, vertical rotor on the tail section, as you normally see on a real life helicopter. Overall, a really good, fun Technic starter set.
