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.

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

I like the new Lego Technic series. My 8 yr old enjoyed his surprise toy in the school party. It is not hard to build. We still haven't converted it from one to another but that shouldn't be a big deal.
