I wonder what this would be like, if the flywheel was in the middle or front, but also in an AWD variant so that you’re getting full traction, along with some wild gear ratios for fun
Hey nice idea maybe I’ll try that soon! Cheers 😀
@@GazRsExtremeBrickMachines Two flywheels, one for each axis, that way you get AWD plus double the energy stored, without adding steel or lead weights.
Also, you can double the width of the flywheel and quadruple the energy stored.
Also, a clutch would be great to disengage the wheels while flywheel is spinning up.
Isn't there a bigger diameter version of the turntable arcs? Maybe not.
Aaaanyway, now make two more of the same kind of flywheel, add 4wd and center-mount.
@@GeomancerHT YES! THIS 👆
Let it roll down a slope and then up and identical slope. That would be a really good test of how efficient it is. I bet it’s pretty good at storing power.
That’s a great simple idea! I love it. Cheers Jordan!
Good idea :)
:3
Really liked this! maybe test the car outside of the studio, and check how far it will go on just flywheel power (both high and low gearing) in some kind of hallway? or test it outside?
That's a good idea
A treadmill be perfect for that
@@hooningmoose8941 yeah
Hey there thank you very much! I wish I had of done now! I really didn’t expect it to have much energy storage with the king gearing but it surprise me. I’d have to do it on the road where I am and that could be tricky! 😀
@@GazRsExtremeBrickMachines ah ok
The flywheel would deliver much more energy if the weight was as far as possible on the outside of the flywheel...
And for the fast gear transmission you could use a wheele bar, that would work way better.
All else great video :) Thanks for the time and effort
even just in the middle would be better. or have it be front engine frontwheel drive
Hey there thank you for that appreciate it! I just couldn’t get any more weight nearer the edge using these parts so I packed it as much as possible. I guess with some metal/lead I could have done it.
I used a car on the last run, I just thought it was more eventful like that lol 😀
maybe instead you could turn the flywheel horizontal and see if it has enough gyroscopic force to keep it stable
Can only get so dense using legos; they could add steel or lead but at that point we're on the slippery slope to "is it even a lego mechanism anymore?"
Filling in the disc also reduced losses to wind that the two flat spokes were creating in the last iteration.
Flywheels follow a bit of a weird law. If you double the weight it only doubles the stored power, but if you double the RPM you quadruple the stored power. A small lighter flywheel that can spin twice as fast actually stores 4 times the energy. "And since the kinetic energy of a spinning object (E in the equation above) is related to the square of its angular velocity (ω2), you can see that speed has a much bigger effect than moment of inertia. If you take a flywheel with a heavy metal rim and replace it with a rim that's twice as heavy (double its moment of inertia), it will store twice as much energy when it spins at the same speed. But if you take the original flywheel and spin it twice as fast (double its angular velocity), you'll quadruple how much energy it stores. That's why flywheel designers typically try to use high-speed wheels rather than massive ones. (Compact, high-speed flywheels are also much more practical in things like race cars, not least because large flywheels tend to add too much weight.)"

Damn, that thing’s so powerful, IT DOES WHEELIES!!!
That parallel motor set up is insane lol
Lol glad you liked that 😀
I remember having a small toy motorcycle that had a flywheel for the rear wheel. A "rip cord" with teeth on it would attach to the flywheel to spin it up. The bike would easily ride across a room, on a solid floor.
Edit: Turns out it was a Tomy Pop Cycle, from about 1981.
Hey thank you for that I’ll take a look now :)
i love flywheels!
3:20 That was wheely epic
Haha it did amuse me filming this 😀
you should make a flywheel saw!
That would be interesting thank you :)
wow this is really impressive !
Hey there thank you very much :)
Can't believe how much weight that fly wheel car drove up that incline with, expressive and entertaining thanks good work man!
Thank you so much! It really surprised me too, I’m surprised the front wheels didn’t collapses!
@@GazRsExtremeBrickMachines you doing more with it in the future? Maybe make it longer so it stops catwalking lol that thing is awesome
Awesome much more power now!
Cheers Chris!! We love power! Lol
That is impressive I never thought a flywheel could do stuff like that
Adam Savage tried doing this with a massive budget and professional tools and failed... My man GazR's showed him up with Lago well done lol
Haha Nathan I’ve not seen that will check it out! And cheers 😀
Great video, 2 changes I'd love to see:
1. Make it all wheel drive
2. Tug of War with a brick on the car.
I’ll work on it thank you😀
@@GazRsExtremeBrickMachines can you please tell me the tug car used? Or a set that comes close…
So because of the physics of flywheels, you get a much greater return from speed as opposed to weight. 4 times as much, in fact.
If you can find a way to better balance the flywheel so you can get it going to say, 8000 rpm, youll get way more power with a lighter overall design
Hi there thank you for that, I didn’t know that! 😀
This just assumes its as easy to add speed as it is to add weight which isn't true.
Its not even the weight we are directly interested in, its the moment of inertia of the flywheel.
@@Ailtir i guess thats obvious, since it returns 4 times the power, that u need 4 times the torque to get it running, not counting air resistance, which is also squared with speed
Thats extremely cool!!
Thanks Mike!! 😀
Really cool. I get a giggle every time a leggo piece just flies off 🤣
Thx for making flywheel heavier👍
Increase the torque 👍
MORE FLYWHEELS!!!! 3 should be good.
I may try two or one big one next and awd :)
You should make a lego car that can wheelie and stay in a wheelie for as long as possible.
Wow! I loved all the improvements you made! Great work on that all Lego flywheel. I thought for sure you’d have to add weight to it with other materials.
Hey cheers Parker I’m glad you liked it! I think any more weight and the axle would be struggling to cope, I noticed after it had worn the plastic down quite bad lol
I used to have a flywheel drag car toy when I was a kid. It was a blast. I actually still have it and I'm still blown away at what it's capable of
Oh cool I’ll take a look at some older ones
Yay tug of war is back
Hopefully more very soon 😀
You should make like a string pull starter like a lawnmower to be completely clean energy
I like the idea Jacob! Would save me charging all these batteries!! The only issue is the strength side but it would be great if it worked
This thing was surprisingly strong for a wheel powering wheels, and if you. Count gears as wheels, it’s a wheel using wheels to power wheels
Haha hey there I had to read that twice but yes!
I’m going to attempt to make a big hamster wheel for my cats and drive a vehicle 😀
efficient flywheel has all its mass located as far away from the axis as possible. like more of a ring with spokes and less of a disk.
Hey I tried that first time but I couldn’t get enough weight in it just using Lego so I did this 😀
a wheelie bar would be good
i find it very surprising that a lego flywheel has this much power! great job!
Thank you very much, surprised me as there’s no bearing etc 😀
Really cool
Thank you very much 😀
I just realized something that would be a co engineering challenge, flywheel dragster. Basically a dragster that's only powered by a spinning flywheel, and you have to improve the design to get the best run possible
I would like to see an even larger heavier flywheel. Most of the weight I would put as far out on the flywheel as possible. Great work though! I am stunned how much weight it would push up an incline!
2 flywheels, front and back
Hey thank you Josiah! I will work on it! Surprised me too carrying the weight uphill!
Nice👌
Thank you Pawel😀
Let's make flywheel in center and make 4WD :D
Maybe two flywheels and 4WD?
Great idea! Definitely 4wd next. I’ll see if I have enough parts for two 😀
Maybe try making it awd + somehow even a bit more weight to flywheel, or just make another flywheel, put it somwhere in the front for better center of mass and conect it to the front wheels and with the first flywheel too so they would both spin equally fast
Hey Alex I think I will try this next time as the videos have had a lot of interest and a few have requested this! Nice idea cheers
This ting strong, and is a dragster to =))
Make a pneumatic engine powering the flywheel and put a simple steering mechanism in the front
Awesome. Thank you.
This concept need to be used in drag racing
I think you should put some long wheelie bars on the back
I have an idea: put a wheely Bar on the fast one, so it does not waste energy doing a wheely
Hey there I did on the last run but found it fun like this 😀
Damn thing needs a wheelie bar on teh faster gearing!
try making a longer wheelbase so that it can actually use all that energy
Now that you have tons of adjustable weight, the truckload of pins used, could you try balancing the flywheel to increase the max rpm? Removing pins on the outside for a greater change in balance and pins on the inside to fine tune?
I don’t know if the spacing would be the same, but a 2x2 cylinder instead of the bushings on the flywheel shaft might make the shaft stiffer, allowing more rpm as well.
Hey there that’s an interesting idea! I’ve taken it apart now to make something else but I will keep that in mind! Cheers!
If you could make it all wheel drive, it could definitely climb some steep inclines. Keep up the good work!
Hey thanks Bailey! Awd next time :)
Having flashbacks to my Evel Knievel stunt bike.
Wheelied itself to destruction lol, you could maybe make a wheelie bar for it and see how long it would maintain the wheelie for in a bigger area
Hey there I did make a quick one for the last run but only with parts I had on hand 😀
sooo cool
Hey thank you! 😀
I like it its pretty clever!
CRAZY POWERFUL BRUH
Part 3 please!!!!
meant to say, awesome btw! 😎👍🤓
And thank you as ever! 🍺🍺😀
you should make it steerable. Like remote controlled but only the steering wheels
Cool seeing you implement the suggestions we commented in the last video. You did a good job filling in that flywheel nice and solid.
Hey there thank you so much! I do really appreciate the input 😀
Model is very interesting! I think you should make it 4wd
I will do and thank you 😀
Thanks for the tug o war lol. Your videos always amaze me.
Haha cheers Mason! Powerful one soon to hopefully compete 😀
Maybe you could use the Lego magnets as weight? They are the heaviest official lego part compared to its size.
use 2 flywheels. 2x torque, 2 x flywheel weight without overstressing the drivertrain
pretty nice video! try to install the flywheel in the middle of the chassis and try to built it an AWD, so it has more grip and its center of gravity is more central
Nice one! Looks like it could use Some wheelebars to not lose as much energy.
cool!
Hey hey cheers 😀
HEY. . . . . . !!! You broke it!!!
Very impressive work! I wouldn’t want to be the guy to have to take apart that fly wheel apart later with all those pins hahaha.
Haha thank you Dave! It was an absolute nightmare good observation!!!
Nice more part
I reckon you could do some truly crazy stuff with the lego ballast brick (part no. 73090b) for additional weight, with a larger flywheel, something to really compete with the high-torque trucks you have.
Hey thank you for that I’ll take a look! I big flywheel would be great too😀
Lego go brrrrr
make a lego drag car!
To prevent the wheelies you should’ve just run it backwards. With the flywheel in the front it would stay on ground
you should add links to some of the builds you do if they have manuals for them
You should put a wheelie bar on and make it a drag car
I’ll make a proper drag version soon thankyou
If more weight is on the outside it also works better
I dare you to make a flywheel with that 6kg lump of steel :D
For real, lego has some very heavy blocks, it would store a magnitude more energy if you built a wheel around some of those. Keep in mind it is very important that the weight is as far outside as possible. 1118 Boat Weight block comes to mind, but that may not be the most practical to keep the flywheel balance.
Hey there Kris the only problem and it’s quite a big one is the axle was just about on the limit here. I used quite a bit of lubrication and even then it was wearing away quite quick.
I will try a bigger one though with some weights thanks for the info too 😀
This model is amazing!! Great build, I have no idea where you get the inspiration! Please can we get pt 3 I’d love to see what other adjustments you could make. KEEP OT UP!
Hey Nick thank you as ever! Appreciate it! If there is a part 3 it will be a big flywheel lol😀
Use those aluminium Lego bricks for the flywheel
You should do big tank vs bulldozer
I will be doing sometime this year cheers😀
Wheelie bar!!!
I did on the last run but just used the nearest parts I could get hold of lol. :)
Looks like you should put a wheelie bar on it for the high speed test
See if you can't turn the fly wheel 90° should create a gyro effect and help stop it from doing a wheelie also would make it easier to feed into say a awd drive train would also be awesome to add one if your automatic gear boxes so it will accelerate faster without as much wheel spin
Wow keren👍👍
Absolutely awesome, needs some back wheels for some take off. I really want to see how far you can take this concept.
Hey thank you so much! Yeah agree, I did put a bar there on the last run :)
Do big tank vs that huge bulldozer or those super strong ones that hold kids maybe?
That moment you need a wheely bar for that lego car
Maybe try steel pins to add more weight to the flywheel
tug of war with brick on it ..... 👍🍺🇬🇧
Hey Carl I did try that but it didn’t go well with trying to move everything out of the way quick haha 😀
a lego brick spin launcher gun, directly detach from the rim, no trebuchet string, just let it go, at a wanted point, with a stopper-detacher, rapid fire mode also, disc keeps spinning, mass disc >> mass projectile
If you'd put this int the "lego saw" from your another video, it'd have much more kinetic energy to cut hard stuff, before it slows down
I will definitely try this thank you! Soon hopefully 😀
You could make the flywheel even heavier by putting a 3L bar inside every 3L pin.
Nice dragster
Hey thank you :)
It so funny how is sounds like a train when spinning up. Its got the classic DC-AC (or whatever) switch sound and at top speed it sounds like a train going flat out
I know what you mean! Love trains!
3:02 like it has a muscle car engine and doing a long wheely.(Like in GTA 5)
Lol Oh I loved that game!
put a wheelie bar on it!
Friction i think is the main problem here. Graphitgrease on the Flywheel Axle maybe can help.
Hey there I did use some lub, the reduction hubs though have quite a bit of resistance unfortunately and they’re sealed units.
I had to use them though for the tyres and secure fitting. Also they can handle serious torque 😀
Wow you did the speed idea i suggested and you also improved my idea and made it strong AND fast! Awesome!
The start of the fast car was wild! I popped a wheelie!
Hey there thank you Blulu for the ideas I really do appreciate it! I will try one more too
@@GazRsExtremeBrickMachines Nice!
Try turning the wheel, instead of the flywheel, to bring the flywheel spinning at extreme speeds!
I don’t think the motors would have enough torque lol. Would be epic speed!
It's like a Top Fuel dragster
Yeah was crazy for a few secs lol
@@GazRsExtremeBrickMachines 😂
At 3:17 that why they don’t put too much horsepower on rear wheel cars
Add a automatic gearbox to the car to make it better for bumpy terrein
I could be wrong but I don't think a heavier flywheel would necessarily make a difference. The energy given to it seems to be limited to the torque available from the spin up motors and the resistance in the system.
For speed add a second fly wheel to the front axle and make is more front heavy
I like the idea cheers! Something for the future!
