Giant Flying LEGO Helicopter!

September 7, 2019


everybody’s norm from tested here once
again at Bay Area Maker Faire meeting up with Adam Woodworth Adam how you doing
Brad having fun even in the rain yeah it’s a little bit rainy outside but
thankfully all the drone stuff is happening indoors and if you’ve seen our
past videos seen Adams videos you make some incredible custom drones this is
amazing is of course Lego copy you have the original copter here is probably six
or seven years old it was from that International Jetport set as a hair poor
with a little jet it was always my favorite of the helicopters and a couple
years ago I did the big lego airplane yeah and I wanted to do something
there’s a little less stressful to fly so I put this guy together okay so a
couple things wants all about one just fabrication right this is scaled up how
many times the size of minifigs scale so this is 10x minifig scale and it works
out nice so that you have one instant relation foam with a couple pieces of
depron foam which is like what they used to make those indoor aerobatic airplanes
yes so you got very lightweight sturdy rigid fabrication wise a lot of curves
here very neat as this all bandsaw is it cnc’d how did you make this it’s mostly
laser-cut so there’s a bunch of free Lego CAD programs so I made a 3d model
of this and then pulled all the 2d surfaces off of it so I could do all the
cuts and then assemble it like a paper model basically even have the full
minifig inside that is so cool I see the light boat in right there that’s really
clever okay so fabricated this together of
course it needed to this rotates oh my god Wow
how does it all fly yeah so obviously like a big square blade is not gonna
produce a ton of lift so the the rotor up top is just kind of decorative but I
wanted to make it spin so there’s a little propeller on here that pulls it
around slowly as it’s flying around and then the actual lift comes from a
quadrotor that’s kind of hidden in the legs you design systems are
untraditional using multi rotor ray like this is quadrotor now how much testing
or how much calibration is needed so the stable so I did a fair amount of tuning
before I painted it I’d like to put the little guy in it and did all the details
modern kind of quad flight controllers are pretty good out of the box so it’s
just kind of tweaking it to match the dynamics to the aircraft then you’re all
good but I always have a rule that I never like do all the detailing on
something until I’ve proven that it flies so you don’t need to like add
weight in a certain place change the center of gravity much the controller’s
gonna I mean this is light enough that the whole thing’s only about four pounds
so for something this size the dynamics are pretty slow very very cool uh what
other projects are you working on I see on your Instagram AJ would peace you
guys have a lot of projects yeah so I always like to kind of keep something on
the backburner working right now I’m kind of on a submarine kick so I’ve been
taking a bunch of like Star Wars plastic models and then putting submarine
internals inside of them and kind of flying them around in water so lets you
get that like cool space motion yeah at like a scale that I can work on in the
backyard it’s almost a computer control right then you can film it and it can do
spins and and multi axis movement the greatest compliment I got on one of
those is like somebody’s like this looks like kind of lame CGI I was like I know
it’s real it’s real that’s exactly what the old movies were like right awesome
one last thing this this canopy here vacuform yeah it’s a big back form piece
off of I think it’s PT G so like a soda bottle material and I made a big plywood
form same process like pull all the 2d surfaces off glue it together and then
it took a few poles to try to get one that came out right but it came out
pretty good I hope you don’t stop making large size Lego flying Lego because this
is such a cool thing you’re gonna take it up I’ll take it up for you guys and
share you flies all right let’s go look

  1. Norm is honestly one of the best interviewers anywhere ever. His ability to ask relevant and interesting questions is so underrated.

  2. sooooooooooooo disappointed that it is a quadcopter and not a functioning helicopter

  3. I've seen him on Flite Test, where he was able to fly a Lego model plane that was made out of foam board, which similar to the way he made this helicopter. This man makes childhood dreams come true and I respect him for it

  4. Clickbait much? Sure, it's cool, but it's neither lego, nor helicopter. This guy's creation: https://www.youtube.com/watch?v=NOptzQP4bJU is way closer to that. But I guess "quadcopter with oversized foam frame made to look like lego heli' wouldn't bring nowhere near as much views, huh?

  5. It gives the "illusion" of flight while actually flying! really cool and kinda surreal looking, gives me some ideas..

  6. Fabricating pieces is a dying skill. Everyone’s using 3D printers which sorry to say takes no skill. It’s great that people not skilled with their hands can build and create, but I like building and fabricating things by hand. Using saws. Grinders etc. Even in my business everyone’s going to scanners where we still cast our patients and mod with plaster by hand for a way better custom fit. Just sad cause I can see very skilled craftsman being gone within a few decades leaving us with men who can build anything until the power goes out.

  7. So much time and effort involved. Only question is why weren't the studs scaled appropriately? Seriously cool project though. The slowmo rotor is freaky.
