mocbuild101 posted a topic in LEGO Technic and Model TeamIt's finally here - my studless remake of the very first Technic helicopter: It's been a bit of a long journey to get here, not only because of the work put into this model, but also because of the many failed TC15 entry ideas... Originally, I had planed on building a replica of the Hoversurf S3 2019 Hoverbike (which is basically a quadcopter you can ride on), but the small size of Lego propellers restricted me to such a small size, that I just couldn't fit any functions into it. Next, continuing the idea of some sort of quadcopter, I did some googling for other quadrotor aircraft, and although I managed to find some (in particular, the Curtiss-Wright VZ-7 and X-19), that idea also failed... Then, after a few days of thinking, I decided to just make something completely different - a flight simulator, based on the 8485 Technic Control Center. With this idea, I actually managed to make enough progress to post a WIP topic, and stuck with it for a several weeks, until I sadly had to abandon that as well... Finally, after trying and abandoning a few other ideas, and with only a few weeks left before the contest deadline, I stumbled across the idea of making a modern studless version of set 852 - the very first Technic helicopter, and one of the original four Technic sets released in 1977: Fast forward 3 weeks, the contest deadline has thankfully extended by 2 weeks (thanks @Jim ), and I've finally finished building... Features: Full studless construction - not a single stud in sight! Near perfect 3/4 scale (relative to the original set). Accurate collective rotor pitch control - unlike the original, where the rotor pitch is decreased when the swash plate rises. Manually powered drive train - can also be motorized, as seen in the video.
