    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.

    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.

    The best Inexpensive Lego Technic Set
    | 14-18
    I would recommend this to a friend!
    Purchased for: Self
    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!

    Main Build is Great, But The Second One Wrecks It
    | 14-18
    I would recommend this to a friend!
    This 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. Overall: 75% 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.
