I had an idea for a very strange kinetically powered helicopter. An unfortunate design error made things go off the rails. Despite that, fun times were had by all.

  1. If you don't already spend time every day learning new stuff, you should! I'm forever amazed how much I learn by cultivating this habit. If you're interested in learning technical stuff, you should check out Brilliant. It's an awesome tool that you can use to learn math / programming / data analysis / etc. If you go to https://brilliant.org/StuffMadeHere you can try it free for a month & get 20% an annual subscription.

  2. Would be interesting to see you try a contra-rotating setup with mass concentrated in the rims of 2 shrouded rotors

  3. Can't the rotating blades be made into a flywheel themselves? I mean get some mass into them and then you'll be able to get rid of everything else in your design, you'll be back with just the blades and the stem and then it won't matter that it spins

  4. What program does he use for his image demonstrations? Just curious.

  5. so…. if you had flown that model plane you showed you would have had some idea of the scale of the problem. swap fixed and moving portions of the "wings" so you would be within an order of magnitude of what you needed. also put them right below the prop. and the "training gear" aka needles sticking out of a semi-truck. with no "off" switch. none of this is meant to belittle or berate – make a crazy flying thing but how about start with a known good / successful flying thing ?

  6. Couldn't you make a counterweight, that is geard to spin in the opposite direction as the prop shaft , in the vertical axis, that would directly counter the torque from the prop shaft in the same way you added a second flywheel to counter the first?

  7. I’d be interested to see what would happen if you used the main propeller shaft as a sort of pyrotechnic cannon, taking the chute above the spinning blades!

  8. Instead of looking for a geared flywheel would mass on the prop shaft not just solve it? No mechanical parts required

  9. I thought you were going to make the shaft the the fly-wheel, with some kind of internal clutch.

  10. So I've been thinking about this for a couple days and just remembered a cool train. There was a short-lived monorail that used a pair counter-rotating gyroscopes coupled together to make a train car balance on inline wheels. They key was making the flywheels 1- gimbaled and 2- geared to each other so their procession was canceled out.

    I'm not sure how you'd incorporate that into a flying machine… but if anyone can figure it out, it's you. The channel Primal Space has a great video on the monorail. Love your stuff, man. Big inspiration!

  11. May I just say: WHEEEEEEEE!!! I had one of those dangerous string-pull air dancer toys as a kid, so that flight path is familiar. Way, way higher, and unobstructed by drywall, relatives, and similar breakable objects. But familiar.

    I am like 90% sure the twisty thing is why grown-up helicopters have those pokey-out tailfin things with the little sideways propellers on them. They are pokey-outey for leverage, so the sideways propeller can be of reasonable size, and then it can be used for steering, too. Not, like, normal, reasonable steering, though. Freaky helicopter steering. (It's amazing that helicopters work as well as they do. Did you know they're not required to have black boxes in them? That's insane.)

    I look forward to whatever bizarre mechanism you come up with just to try something different from existing, proven designs!

  12. You have the coolest job next to the guys at vsauce.

  13. go CO-AXIAL !!! , and four mini FPV style props for roll and pitch control (which can double as an extra/emergency thrust should your autorotation be miscalculated!!) If you dont want to use batteries (which i totally understand), maybe the flywheels can double down as alternators too… I wouldnt use the original props for pitch and roll bec that would just be a classic helicopter and increase the complexity.. Love your videos!! huge fan (Ba Dum Tss)!!

  14. In the future, we will see a news clip of stuffmadehere accidentally shrinking himself or the kids.

  15. I haven't seen your lady this enthusiastic ever I think! Looks like a win!

  16. What what happened if he put another set of flying wheels spending in the opposite direction of the other two? So that would be flywheels on all four sides.

    Or

    One horizontal flywheel on the bottom of the helicopter spinning in the opposite direction with a gearbox transfer the power?

  17. Just buy an RC heli 😂

  18. isn't the torque of the rotor spinning everything in the opposite direction with no way to counter that torque because you have no side rotor or counter-spinning set of blades below it? And do the wings even work? Like most of the air going over them is just turbulent, right?

  19. If that wing solution would be feasible, helicopters would not have a tail rotor (or double rotors spinning in opposite directions).

  20. long time viewer here, I love the new pacing and the clear changes in skill over the years, wish you the best in the future 🙂

  21. Those aeleroms are nowhere nesr big enough….considering you used a precision aerobatics katana as a visual aid…precision aerobatics planes are notorious for having huge wings with large control surfaces because theyre designed to fly 3d aerobatics which the majority ofnmanuevers are done post stall and not using the airfoil….the key is huge control surfaces guiding the theust from the prop….the ailerons you employed are more for a wing with an airfoil and ustilizinf the wings lift….in this situation its not using a wing to fly so your going to need obnoxious cintrol surfaces to get the same affect because its relying just on the air flow thats the thrust from the prop nothing else is contributing to the lift on this application…that would be my theory

  23. She’s a keeper!

  24. That pyro parachute cannon to get it far from the blade ks exactly where my mind went at first and maybe a shaft brake to stop thenprop when on descent

  25. I vote for counter rotative blade solution 😀 It could allow to keep the current clean design in comparison with a tail rotor.

  26. По мнению автора второй винт у вертолётов видимо для красоты

  27. Pivot the project to a flywheel powered helicopter. You can cancel your torque spin with a tail rotor and it would be interesting to see how you approach machining a swash plate

  28. Why not put the flywheel on the shaft itself so it spins in the same direction as the propeller??

  29. This quit being a kids style helicopter as soon as you started.

  30. The us military actually made a supersonic propeller plane. it was so loud it sent a man into cardiac arrest. I think the nickname was the thunderscreech.

  31. Try a Russian version instead of the wings!
