Our customers say

LEGO Technic - Ultralight Helicopter - 42057 is rated 4.5 out of 5 by 6.
Rated 5 out of 5 by from The best Inexpensive Lego Technic Set This is my first lego technic set, and although it was very challenging to build, it looks amazing, has amazing play features such as the spinning propellors and the moving rudder, is extremely fun to build and is amazing value for the price you are paying for this! The wheels were done differently and very nicely, and I absolutely love this Lego Technic set as my first set of this theme. Nothing bad to say about this! This does take a lot of time and concentration if you are new to Lego Technic!

Rated 4 out of 5 by from Something More, Many Don't Know This set looks good and does have a decent selection of movable parts for the price, but the real reason I bought this set is one it seems many don't know. This set #42057, combined with #42061 Telehandler, and #42063 BMW R 1200 GS Adventure, are all necessary to build a special 40th Anniversary Technic Set. The instructions don't seem to be common knowledge, but the PDF Instructions are out there. The special car is a tribute to the #8860 Chassis that was available in 1980. Thought I would pass that on to Technic Fans, incase you are interested in such.

Rated 5 out of 5 by from "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.

Rated 5 out of 5 by from Lego Technic 42057 The 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.

Rated 3 out of 5 by from nothing moves when pushed The only way to make the props move is to move them by hand then the engine moves. Should have been connected to wheels so the props and engine move when you push it.

Rated 5 out of 5 by from A great little helicopter Being a fan of aircraft and owning every Technic aircraft set released by Lego in the past 14 years, I have to say this is a great example of an ultralight. Although I've only flown an ultralight plane before and never having been in an ultralight heli, I am familiar with the mechanics of ultralights. This entry-level Technic set is for beginners and children to enter the world of Technic and aviation. This small set has a lot going for it in terms of a 2-cylinder engine, quite a few axles with gears going to the top rotors and rear rotor behind the cabin, and the color scheme is perfect. The set is very interesting and appealing to both the eye, but also just screams, buy me and build me. Swooshing it around and turning the gear knob to engage the rotors is loads of fun for both children and to adult fans alike. I highly recommend this set and at the price point you get a lot of bang for $20.
