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
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.)"

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
Damn, that thing’s so powerful, IT DOES WHEELIES!!!
You should make a lego car that can wheelie and stay in a wheelie for as long as possible.
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 :)
That parallel motor set up is insane lol
Lol glad you liked that 😀
i love flywheels!
Really cool. I get a giggle every time a leggo piece just flies off 🤣
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
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
Make a pneumatic engine powering the flywheel and put a simple steering mechanism in the front
Awesome much more power now!
Cheers Chris!! We love power! Lol
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 😀
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
Thx for making flywheel heavier👍
3:20 That was wheely epic
Haha it did amuse me filming this 😀
I think you should put some long wheelie bars on the back
MORE FLYWHEELS!!!! 3 should be good.
I may try two or one big one next and awd :)
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…
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 😀
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
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 😀
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
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
a wheelie bar would be good
That is impressive I never thought a flywheel could do stuff like that
Thanks for the tug o war lol. Your videos always amaze me.
Haha cheers Mason! Powerful one soon to hopefully compete 😀
try making a longer wheelbase so that it can actually use all that energy
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
To prevent the wheelies you should’ve just run it backwards. With the flywheel in the front it would stay on ground
Use those aluminium Lego bricks for the flywheel
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 😀
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 should make a flywheel saw!
That would be interesting thank you :)
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
This concept need to be used in drag racing
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 :)
Increase the torque 👍
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😀
Do big tank vs that huge bulldozer or those super strong ones that hold kids maybe?
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!
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 😀
Having flashbacks to my Evel Knievel stunt bike.
Model is very interesting! I think you should make it 4wd
I will do and thank you 😀
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😀
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 😀
Damn thing needs a wheelie bar on teh faster gearing!
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
you should make it steerable. Like remote controlled but only the steering wheels
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!
Thats extremely cool!!
Thanks Mike!! 😀
make a lego drag car!
Looks like you should put a wheelie bar on it for the high speed test
You should put a wheelie bar on and make it a drag car
I’ll make a proper drag version soon thankyou
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 😀
Part 3 please!!!!
Yay tug of war is back
Hopefully more very soon 😀
you should add links to some of the builds you do if they have manuals for them
You could make the flywheel even heavier by putting a 3L bar inside every 3L pin.
you should have a 24 tooth gear on the flywheel to the wheel. you’ll have a lot more torque but the distance it goes will be shrunken. rn it seems like your hearing is just 1:1 and it’s getting a lot of torque and high rpm’s. i have the 40 to 24 gears on my pullback dragster and it makes crazy torque with the stock lego pullback motor. i feel like doing that will benefit you in the amount it will pull/push
Hey thanks for the tip I’ll look into it next time😀
That moment you need a wheely bar for that lego car
Put in the efficiency, the energy used to speed up the flywheel, and the energy that the fly wheel can deliver...
I don’t think it would end up too well! Someone mentioned about having two slopes to see it go down and back up again on its own power to see this!
Nice one! Looks like it could use Some wheelebars to not lose as much energy.
wow this is really impressive !
Hey there thank you very much :)
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 :)
I like it its pretty clever!
Love the video! Please do a V3! :)
Is it possible to get the flywheel up to say 4000+ RPM? Also consider using heavier materials like metals for the flywheel.
Hey there thank you I’m glad you like it, thanks for the tips too 😀
I switched the gearing a few times but I think it was maxed out at this rpm. Without the drivetrain I spun the disk at 3500 rpm. The axles were twisting too as there was so much load on it.
use 2 flywheels, front and back. the load will be divided on 2 drivetrains so the axles won't be overtwisted
You should do big tank vs bulldozer
I will be doing sometime this year cheers😀
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!!!
HEY. . . . . . !!! You broke it!!!
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
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 😀
Maybe try steel pins to add more weight to the flywheel
Awesome. Thank you.
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 😀
That’s amazing!! The car pulling wheelies was definitely the best part😂 very impressive how much torque it has! Also 65k!!! What!!
Hey Easton cheers after a quiet two weeks it’s going well again😀! Yeah I had fun with this lol. The hill test with the weights blew me away!
@@GazRsExtremeBrickMachines it’s crazy for sure! What if you did 4x4🤔
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!
This ting strong, and is a dragster to =))
Wheelie bar!!!
I did on the last run but just used the nearest parts I could get hold of lol. :)
Try a design with a smaller diameter, and longer cylinder. This is what sum busses, and even some prototypes F1 cars used to experiment with.
Hey cheers I’ll have a look! I know the lmp1 cars used this a few years ago to store energy to then power the motors on corner exits!
put a wheelie bar on it!
CRAZY POWERFUL BRUH
If more weight is on the outside it also works better
meant to say, awesome btw! 😎👍🤓
And thank you as ever! 🍺🍺😀
Really cool
Thank you very much 😀
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!
Nide video, love it what people build for crazy machines with lego ;)
Hey thank you so much !
good improvements, I would really like if you can made a LEGO car with a propulsion system of rubber band, like attach 2 rubber bands to a wheel and turn them lol
Hey thank you very much! I remember doing things like that when I was younger with aeroplanes! Was so fun! Would be interesting taken to the extreme!
@@GazRsExtremeBrickMachines Ouu!
3:02 like it has a muscle car engine and doing a long wheely.(Like in GTA 5)
Lol Oh I loved that game!
Now create mechanism that absorbs/transfer crash energy into flywheel. Some kind of a bumper that gets pushed in and spins flywheel
Hey that’s a bizarre but interesting idea!
Nice more part
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
this was great! next you should put some sort of metal in the flywheel somehow
Hey thank you very much I’ll see what I can do
It reminds me the Gyrobus, which actually run in regular service for years.
Wheelie bars next time please!!!
I did at the end :)
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 😀
I'd like to see it go down a ramp freewheeling and then with the flywheel attached to see the efficiency difference (aka how far it goes)
make pls 4x4 with Flywheel Energy Storage
(lock AWD)
I nearly did as it was an easy conversion but I didn’t want to lose to much energy through the drivetrain.😀
