Lol cool video
Good job bix .. I wonder if a coaxial setup would b more stable id like to see this on the store so simple and easy for kids to get into a basic form of heli flight
why? did the devs figure out that theyve trashed their once great game and actually fix it? you guys have almost talked me into logging into my account to find out.
Your dihedral is not applying forces the way you think it is. The gyroscopic effect means the force is applied 90 degrees ahead in the plane of rotation. This would produce the spiral tendency. Try without dihedral and add more weight below.
Have you ever had the chance to see Jim Walker's "Ceiling Walker"? Also, how bout an R/C control line aircraft with throttle and elevator flying on a tether center pole? Bob could get into this one!
These kind of videos are my favorite. Love watching ideas become reality
Me too
Me toooooo
dihedral does NOT work in a rotor, if you apply a force in a spinning wheel the torque has a 90 degree shif so that is why it is flapping around
Exactly. Law of gyroscopic procession.
"OHH MYY GOSHH! I ALMOT DIEEED!" Best part XDD
Design is okay but what could be added is a weight on a string so every time the whirlybird turns one way the wait on the string lags behind and pulls it in the opposite direction. That would counteract all the movements of the whirlybird
pendulum balancer
I would guess, that just adding a weight on a string wouldn´t lead to any advantages. You would need some kind of dampening of the balance weight. Otherwise it will start oscillating quite badly, I suppose.
Try adding a secondary rotor on the bottom of the pole which turns the oposit direction (using the downforce to propel them) so it auto corrects itself. And to maybe improve on that adding weight like flywheel to the bottom aswell would stabalize itself like a gyro
Won't work. Google "pendulum rocket fallacy"
It would work far better by deleting the stick all together.
@@cgrant26 This isn't a rocket. The pendulum effect is the reason paragliders and high wing monoplanes are stable. The issue here looks like the torque of the rotor causes a kind of gyroscopic procession which causes high angles of attack of the blades. A counter rotating mass at the base might work to counter it, as well as a free pendulum, that way you could also mount the batteries in the bob.
2:45 The laughing goes so well with the sound hahaha
@7:45 ** and yeah hahaha I was gonna comment on the same thung
Oh, so they're called whirly birds? I brought a bag of odd props from my mini quad crashes to work and let my students just glue them to dowel rods and see what flew best. Tons of fun!

@@aborelli and wire them in with power. so they run the whole day.
This is the type of episode, the old fans enjoy! Good job guys.
Without reading all the comments to see if it’s already been suggested but... use an EDF mounted through the centreline blowing into a hollow pair of wings, allowing the thrust to escape along the trailing edge or maybe through tip ducts. You should get the thrust and lift with less of the gyroscopic forces. You may need paddles in the EDF to help prevent torque reaction. You need to test out this theory!! :-D
like the first steam engine, or a spinning sprinkler, nice idea.
This could most certainly work.
Duct sizing and taper of the duct will be most important.
Yes, IT IS feasible idea: ruclips.net/video/CSZqFoOiyF4/видео.html
The efficiency is not that good, though.
@@shinjisan2015 - The Aeolipile!
Oh like those balloon copters
I like that these videos don’t waste time. So many videos like this are just 20 minutes of explaining and not much doing.
Dihedral is not your friend because of gyroscopic procession. The self righting force is 90 degrees out of phase and is causing, not helping, the swirl.
Is there a way to pulse the motors using the gyroscope sensor to level wing/propeller. I just don't know much about this stuff. Sounds interesting.
Krinje
Percivalpresto
Dangit, now I want to see how it works with that adjustment
dihedral would help with a 2 blade prop
I like rc aircrafts but what you just said melted my brain
Man youre very smart
can you guys make a AREAL SCREW, I WOULD LOVE TO SEE DAVINCHI FLY
Jerreinemy sorry to burst your bubble but the aerial screw has been proven to be physically impossible
@@tacticaltaco8102 If it is operated by men the power to weight ratio won't be enough but if the power comes from a lighter source like a rotor it's not impossible.
@@tacticaltaco8102 definitely not impossible just not so much screw shaped but a cross between a screw and a disk
You can cut a circle into a large spiral shape and see it autorotate and fall slowly
Jon Snow you just pretty much just made a helicopter
@@tacticaltaco8102 i just mean even if you had to use props on like this build even a very steep pitched screw you could still make it fly
So not impossible
Like Something ive heard with enough thrust you can make anything fly
Definitely a success! I'm sitting here laughing like I'm some kind of mental patient. My wife's looking at me like I'm crazy. Excellent video guys thanks for sharing.
Your wife may be entirely correct! But if so, I'm the same kind of crazy :D
I always get a good laugh watching you guys. Reminds me of when I was young building muscle cars. "That should work"
It would be awesome if you were able to make a gigantic quadcopter with 4 props like this!
This is great!! If you added a longer pole and a much lower center of gravity, would it not amplify any of the oscillation?
Loved that experiment!
Can you make the big plane from seek and destroy.
You guys are children at heart, and I greatly appreciate it. Keep being awesome!
You guys should make some bombers, not the nerf ones but model ones
Like with servos and hatches and 3d printed bombs
God I love you guys way more in the winter when the gears are turning! Bravo! badass rotor wing thingy
Darwin award in the making , put a metal blade on the tank in the beginning
Also what, micro beaver on the wall
It's like my worst dream with hallucinogens.
Very funny
Best youtube content out there👏
Could you control it with differential thrust, tied into a flight controller?
Next challenge!! Umbrella that can lift a person like Marry poppins.!
To fix your balance issue try thinking of a car tire and how they balance it using weights, try that... Maybe even have a circular piece connecting the 2 or 4 wings together and adding small weights accordingly. Then large props end of wings for the torque and smaller props in middle to get that speed.
handle with bearings
@@stevemoney6613 yeah I was thinking same.

MARV lol hey there marv!
@@gracklefpv8811 Oh hi there
Fractal aircraft! Brilliant! 😁
String theory RC; The Quantum multirotor.
...and call it the "fractal motor rotor" :D
Good One! this one brought me back! It needs two winglets on opposite sides this will slow down the rotation and give stability, I've done something like this one back in the late '70s using rubber band power. I made a fuselage then mounted two winglets equal in length of the fuselage, the boom is then placed about 80% up on the body with the boom running threw the cross-section then mounted the winglets on either end, it was a successful flight! about all I can remember how imprest how high it got!
Wow, this might be my favorite FT video...
RumbleLab it’s mine behind rocket plane
It's incredible. It looks like one of those mad seeming, but absolutely terrifying 'what if' machines developed by German scientists during the last war, and found abandoned in a secret facility by the allies as they retook Europe in 1945. You could have put a gimballed counterweight on the end of the shaft - or a gyroscope, to keep it level; the whole thing is basically a huge, powered dandelion seed. I'd like to see you revisit this project.
Ahh yes, good old pendulum rocket fallacy. Guess gyroscopic stabilization doesn't help much.
cgrant26 Goddard also fell for this fallacy.
You guys are living the dream. Congrats on all your success.
Dihedral for stabilisation? Wait, I'm thinking it'll apply 90 degrees out of faze due to gyroscopic procession, making it do that wobbly thing you keep seeing. I'd suggest trying it with no dihedral and relying on pure gyro effects to keep it level a bit longer.
Am I getting this wrong? Dihedral on the rotor should make it inherently unstable, right?
That is actually a logical point. Helicopter rotor inputs are 90* off the desired movement due to gyroscopic precession. It would follow that the righting force of the dihedral would cause a 90* shift.
If you look carefully at a rotor system in flight you will observe inherent dihedral resulting from lift generated from ends. 70% of lift comes from the 30% at the far end of the blade.
Gyroscopic fly weights situated at 90 degrees to the blades controlling blade pitch is how Bell stabilised their teetering system.
This is the kinda thing you think of when you're bored as hell and then do because honestly it's funny as hell - and it is XD
I think you have to put some mass at the end of the conduit to keep it stable in air.
These guys remind me on my brother and I as kids screaming around in the garage . Only with cooler stuff! love it
This looks like you guys just picked up some failed ussr ww2 research
Me, my dad, and my grandpa all just got tickets for flite fest!! 3 generations of experience. Can't wait!!
Oh also. We all fly mode 1 :)
The vibrations were probably from gyroscopic precession
needs a teetering rotor head :)
@@freezatron lol, that and a whole lot more too.
Most likely. Forcing the propeller/motor to rotate through the air puts a lot of torque on the motor mount itself. Plus the vibration is probably coming from the propeller, due to a bending in the propeller.
LOL I got SO HAPPY when I saw the tank lift off the ground!!!
I made this suggestion before- monocopter. Looks like a maple seed. One wing, with the motor pod at the root, or on an extension stick, as a counterweight. CG is at center of rotation. You launch it vertically off a wire, like a model rocket. An RC trim tab on the wing can be pulsed to add steering. Lockheed worked on this idea a a pocket sized drone platform for combat scouts. Kids used to make these as free-flights with Cox .049 engines back in the day.
Unless you articulate the "blades." that will always pitch up and roll left. The blades must be able to flap to compensate for dissymmetry of lift in forward flight. It's a helicopter thing...
if there's any significant forward airspeed, yup.
Lol even the men in black were keeping their distance indoors (safety first) ! Love these kind of builds.
I am also interested in making RC toys, I make RC ships, drones, rc cars and helicopters, etc. I liked the way to explain you, very thankful.
That was so much fun watching you guys be Mary Poppins
genius
FANTASTIC!! You need to address the gyroscopic process issue though. I'm building something similar, but with the motor/props are at 90 deg to yours, plus a duct changing it back to a tangential thrust like you want.
Your definition of “It worked” must be completely different from mine.
Lol right? I've had days where I got a homebuilt POS to actually fly but always in my videos I was like 'Well, that pretty much sucked!"
You guys are hilarious. This is what the hobby is about!! Stefan tho!! And the guy rolling in the snow!!!!!!!
Man I love you guys. 👌😁
You guys are just the most wholesome family fun on RUclips, I can't wait to get my future kid interested in flight.
I JUST NOTICED A WING STYLE YOU HAVE NOT TRIED YET. The rotating wing that uses the Magnus Effect to generate lift
I wanna see that.
Have they done a cyclogyro yet? Would like to see the results from that also. Well, it could result in a lot of fail, which would be fun to watch also.

Amazing video keep it going
Hey guys you should try making a flying back pack with school stuff in it
These guys are living the dream. A nice counterweight at the bottom of the pole would have helped a lot!
I think a goofy torque is going on with the blades.
ya i think it's some kinda gyroscopic thing, "Precession".
Your whirly-bird toy flies very stable at high RPMs, and if you notice as it slows down you will see it behave like the motor-on-a-rotor did. Higher RPMs on your prototype will stabilize the gyroscopic precession effect. Also, since the energy applied to the whirly-bird comes from the shaft, and not the rotor blades, it might be worthwhile looking into mounting the electric motors on the shaft. I would try mounting the motors on arms about a foot away from the shaft, and have the batteries attached directly to the shaft to minimize rotational inertia. Lastly, since speed is the key to stabilization, not lift, it might be a good idea to try making the rotor blades without much camber. Just brainstorming...love you guys!

With nothing to account for gyroscopic procession the rotors pitch will continue to increase. Very fun to watch. Thanks for sharing!

A little more weight on the bottom of the down rod would have helped a lot.
Exactly !!!
Yup I was thinking the same
The rod needs to be longer not heavier
sorry chaps but you're all wrong :)
what it needs is a teetering rotor hub to solve the gyroscopic precession problem ;)
@@freezatron or just a quad board and 4 motors sideways on the bottom to stabilize it and to direct it.

is there any console game that flies realistically? I mean, when you roll 45°, your plane is supposed to slide down and to that side.
@@darkswami war thunder is pretty realistic. Especially if you play realistic mode. I think it just came to Xbox recently. Out on PS4 to.

You can get started for under 100!
All you need is your imagination and some foamboard to get Scratch Building!
You can easily make a design for a simple Chuck Glider, and then complicate it as you feel ready.
Or you can use a free design off the web! (Like one of FliteTests designs!)
Yes I know
I'm planing on getting some foam board for chuck ones and move on from there
Then you just need a transmitter, ESC, motor, battery, charger, and a few servos!
this is such a cool concept. i remember some little spinning flying things i held in my hand and twerl really quick and it will take flight for a few seconds. this is just like that! make it into a controllable drone would be awesome
