Very fun, fast and ingeniousI purchased two copies of this to put the A and B builds on a shelf together. Both are really quick builds and look good. It took an hour to build both of them.
The rotors are clever and I thought they would be tied to the wheel, but this is not how it is in the original builds.
The designer did a good job on both designs, they are clever and the A build rudder controls are well done.

Main Build is Great, But The Second One Wrecks ItThis was my first ever technic set, and I was definitely impressed. Of course, I built the primary build first, so I’ll start with that:
Primary build: 9/10
This build used up all the pieces included, so it did take
longer to build than a typical $25 set. Still, the final product was mind blowing. Just by turning a gear at the base, the rotors would both turn at the same time. That completely steals the show from the other parts of the build. Still, the build is very display able and looks great. The only downside is the feature where you could move the rudder/vertical stabilizer from side to side. It gets stuck sometimes and to me it feels unneeded.
Secondary build: 6/10
I built this one quite sometime after building the primary build since I was so happy with it. But when this one was built, I was disappointed. Over 1/3 of the pieces hadn’t been used, and the main feature wasn’t nearly as exciting as the primary build. That isn’t it, though. The shaping is a bit weird looking especially because of the ackwardly undersized wings. I understand that Lego was trying a new design and shape, but if you ask me, it just doesn’t work out. In fact, compared to the primary build, it looked so lame and ackward, I rebuilt the primary build just the next day.
I feel this set had a strong primary build, but when you came to the secondary build, it just wrecks the set. They could have just left the secondary build out, or tried to use up more pieces for it. On top of that, the set used way too many stickers and the price to part ratio is just okay. Still, I would recommend it to anybody who wants a challenging but rewarding build.

Lego Technic 42057The moment I saw this I knew I had to get one. The helicopter and aircraft design appealed to me as I love aircraft, space ships, and rockets. Opted to build the Experimental Aircraft and enjoyed the building experience. I expect to get some playtime with it and my daughter who is also a Lego Fan. The moving parts (pistons and propeller) are a cool addition, although it would have been great to have them move while you roll it. The color combination is also very appealing. Very sturdy, can take some rough handling, and rolls easy on any level surface. A stand for this kit would also be great for those who build them and have their Lego kits as display models. Highly recommend you get one. It is a great kit for the price.

"It Simply Blew Me Away"I I built this using the digital building app, which was very fun and unique. There is a lever on the side that rotates the tail fin. There is not a crank to spin the rotor blades. It is operated by rotating the light tan gears on the bottom. I really like this little helicopter. However, I think that some experienced Technic builders may dislike the abundant use of stickers. I personally have no problem with them because without them the build would look very plain. I really liked the 40th anniversary brick, and to my delight it was a printed piece. I think that it is one of the better small Technic sets of year.
