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
@@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.
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.
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.
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?
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! 😀
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
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 😀
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.)" www.explainthatstuff.com/flywheels.html
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.
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
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 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!
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 😀
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 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
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
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.
The car charges up the flywheel when it goes down the slope again. Maybe you can use another slope in the Opposition direction to make a pendulum where the car goes back and forth between the two slopes. By looking at this you could compare the efficiency of different setups. Apply lube to the gears, see if it oscillates for a longer time.
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.
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
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
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
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!

maybe instead you could turn the flywheel horizontal and see if it has enough gyroscopic force to keep it stable

Hey thank you for that I’ll take a look now :)
you should make a flywheel saw!
That would be interesting thank you :)
3:20 That was wheely epic
Haha it did amuse me filming this 😀
i love flywheels!
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

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…
You should make a lego car that can wheelie and stay in a wheelie for as long as possible.
MORE FLYWHEELS!!!! 3 should be good.
I may try two or one big one next and awd :)
Awesome much more power now!
Cheers Chris!! We love power! Lol
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 😀
Increase the torque 👍
Really cool. I get a giggle every time a leggo piece just flies off 🤣
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
Thanks for the tug o war lol. Your videos always amaze me.
Haha cheers Mason! Powerful one soon to hopefully compete 😀
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 😀
Thats extremely cool!!
Thanks Mike!! 😀
That is impressive I never thought a flywheel could do stuff like that
Make a pneumatic engine powering the flywheel and put a simple steering mechanism in the front
I think you should put some long wheelie bars on the back
Model is very interesting! I think you should make it 4wd
I will do and thank you 😀
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 😀
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 :)
Nide video, love it what people build for crazy machines with lego ;)
Hey thank you so much !
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 😀
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!
wow this is really impressive !
Hey there thank you very much :)
try making a longer wheelbase so that it can actually use all that energy

You should put a wheelie bar on and make it a drag car
I’ll make a proper drag version soon thankyou
a wheelie bar would be good
Part 3 please!!!!
meant to say, awesome btw! 😎👍🤓
And thank you as ever! 🍺🍺😀
This concept need to be used in drag racing
make a lego drag car!

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
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 😀
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😀
You should do big tank vs bulldozer
I will be doing sometime this year cheers😀
you should make it steerable. Like remote controlled but only the steering wheels
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
Really cool
Thank you very much 😀
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 😀
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
The car charges up the flywheel when it goes down the slope again.
Maybe you can use another slope in the Opposition direction to make a pendulum where the car goes back and forth between the two slopes.
By looking at this you could compare the efficiency of different setups. Apply lube to the gears, see if it oscillates for a longer time.
That’s a really good idea thank you! I wish I had of thought if that! I will do another soon😀
@@GazRsExtremeBrickMachines Great. Looking foreward to it :)
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 😀
Yay tug of war is back
Hopefully more very soon 😀
To prevent the wheelies you should’ve just run it backwards. With the flywheel in the front it would stay on ground
Having flashbacks to my Evel Knievel stunt bike.
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!
Do big tank vs that huge bulldozer or those super strong ones that hold kids maybe?
Nice👌
Thank you Pawel😀
Damn thing needs a wheelie bar on teh faster gearing!
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 😀
Awesome. Thank you.
Wheelie bars next time please!!!
I did at the end :)
Nice more part
Nice one! Looks like it could use Some wheelebars to not lose as much energy.
Wow ur subs doubled I’m almost at 150
Very nice video
Hey hey thank you very much! Keep it up and add lots of tags :)
@@GazRsExtremeBrickMachines yup np
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
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!!!
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 😀
Maybe try steel pins to add more weight to the flywheel
Looks like you should put a wheelie bar on it for the high speed test
I like it its pretty clever!
If more weight is on the outside it also works better
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🤔
you should add links to some of the builds you do if they have manuals for them
HEY. . . . . . !!! You broke it!!!
sooo cool
Hey thank you! 😀
Wheelie bar!!!
I did on the last run but just used the nearest parts I could get hold of lol. :)
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!
Add a wheelie bar and make it a dragster
I’ll probably make a dragster version cheers 😀
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.😀
You could make the flywheel even heavier by putting a 3L bar inside every 3L pin.
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

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 :)

Hey Nick thank you as ever! Appreciate it! If there is a part 3 it will be a big flywheel lol😀
CRAZY POWERFUL BRUH
put a wheelie bar on it!
Add a automatic gearbox to the car to make it better for bumpy terrein
It reminds me the Gyrobus, which actually run in regular service for years.
That moment you need a wheely bar for that lego car
Now do the same gear test but with the drive from the main wheels
I don’t think the motors would have enough torque unfortunately! 😀
It's like a Top Fuel dragster
Yeah was crazy for a few secs lol
@@GazRsExtremeBrickMachines 😂
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!
