Interesting Fact: This is how, in some roller coasters, a turbo start with very fast acceleration is achieved. The have to produce mega Joules of force but only for a split second to achieve the insane acceleration( in an amusement park here in Germany one of them can reach 60 mph or 100kmh in less than 1.4 seconds. A motor producing that amount of force would be unfeasable so the energy is built up like this over the course of about 5 minutes with a 5 ton flywheel!
While flywheel based roller coaster launches do absolutely exist, and were produced by a German company, none exist in Germany. Hydraulic, pneumatic, or magnetic launches are far more common methods used on coasters.
Hey Everyone! Sorry I’ve been away for awhile! I hope you’re all well :) A big thank you to all the new and old subscribers who have got me to 100,000 Subs! I’ve got quite a few projects on the go so there should be some regular videos again! As always i appreciate all the feedback and if you have any ideas let me know :)
Hello there! I have one idea for you to try- if you could attempt on making Mars rover type of vehicle- 6x6 or maybe 8x8 drive with some insane suspension, and also maybe a claw to lift some stuff and put into some type of a bow on that vehicle. Sounds pretty challenging but i think it would be easy for you!
@@brickleymotion hey there nice idea! I think they use a rocker type rear axle which work well! I will do something like this thanks! Also a weird 8x8 vehicle :)
The energy stored in the flywheel is 0.5 x I x w^2, where I is the moment of inertia and w is the rotational speed ( in radians per second (= rpm / 60 x 2π)). The moment of inertia depends on the mass distribution through the flywheel, but for a solid disk is 0.5 x Mass x radius^2. This energy is then transferred to gravitational potential energy, which is calculated as the mass of the load (in kg) multiplied by the gravitational constant (approx. 10m/s/s) multiplied by the vertical ascent (in metres), i.e. energy (in Joules) = m x g x h. In your last case before the clutch gave out the machine lifted 1kg by about 50cm (guess) so that gives 5J of energy output. The efficiency of conversion is simply the ratio of these two energies. P.S. don't be disappointed if the efficiency looks quite poor!
You can calculate horse power from this really easily. Hp is defined as how fast a device or engine can lift a weight to a specific height. I think the weight is 500 pounds and the length is 10 feet. That’s probably wrong though. But what you’ve built is almost exactly how hp was invented except instead of a flywheel it was a horse. Very cool and you should totally calculate the hp of the different flywheels.
James Watt, a Scottish engineer and designer of an enhanced steam engine in the late 18th century, gets credit for the term horsepower. He measured how much weight a horse could lift over a known distance in a minute and found it to be a little over 32,500 foot-pounds of force. He then rounded up and divided by 60 to get 550 foot-pounds per second. And, voila, horsepower. So I had the equation a little backwards but the idea is the same. Here is the actual equations you might need to calculate this. en.m.wikipedia.org/wiki/Horsepower
@@letsdosomething6691 Yes, if you measure how long it takes to lift the weight by a height then the power is simply m x g x h / t. I would regard this as being a measure of the power transfer capability of the clutch rather than the flywheel (which is technically and energy storage device)
Clutches are probably one of my favorite creations to see redone in lego. I don't how many iterations you are going to go through, but I'd love to see some of your different itterations along the way!
Flywheels are very good dynamic energy batteries. The largest flywheel I’ve seen in person was a massive 8 foot steel ring about 1.5” thick and 16” wide with chonker spokes. The flywheel I’ve used most is in a machine called The Buffalo. It’s a steel cutting machine with five different cutting implements tied in to one flywheel. I’ve seen it punch through 1 inch thick steel like it was butter with a cold center. The sound was immense and the vibrations through the floor scary. There’s a reason that flywheels are used so often
@@GazRsExtremeBrickMachines Looking back now, it seems when the string winds on the shaft it's essentially changing the pulley ratio by changing the diameter of the shaft. So as it lifts it gets harder to lift. Perfect stress test for clutches and flywheels!!!
You're back! We all missed you! I don't know how you always manage to come up with amazing, outside the box creations. This one was no exception. Glad to have you back. Happy building!
Hey thank you very much! Originally I had no clutch but I couldn’t keep tension in the line and things got messy lol. I do have a different way to do it next :)
I´d use a differential gear as clutch. Just use a tire on one output shaft and the winch on the other. If you then clamp the tire tight to a standstill, all the momentum of the flywheel is transfered to the winch. With this setup, your "clutch" will withstand a lot of torque, just make the lever clamping the tire longer to get more force.
I feel like this rig could use some sort of ratcheting device for a Cleaner demonstration. If you wanted you could also run the line through a pully so the flywheel could be mounted on the ground. Neat demonstration as it is!
@@GazRsExtremeBrickMachines something else i thought of, if your clutch continues to slip you can make a "clutch pack". How they normally work is they have disks keyed to the shaft and a "cage" going around the entire pack, alternate one disk for the shaft and one for the cage until the clutch stops slipping.
@@Sean-Ax lol Awe bless! Food food or a different flavour food to the last 7 flavours…. Charlie’s life long friend/sister(Ruby, was in a few videos) died a few weeks back and he’s so clingy at the moment! He still goes around looking for her which is so sad. I now miss her waking me up at silly times :)
I feel like the flex at the top caused the clutch to give un-even pressure when lifting the heaviest loads... Am curious how much more it could lift with less flex and possibly more clutch force. Great video!
I've missed your videos showcasing your amazing creations. I wish I had a tenth of your ability! Fly wheels can be awesome and fun to experiment with. Looking forward to seeing more 👍
2:41 this reminds me of watching The Price Is Right when I was a kid. I always wanted to see the big wheel spin that fast. 😀 Back then I would imagine someone spinning it. Then it starts spinning faster like a run away diesel until it self destructs. 😂
Very impressive! I think a bigger version of such flywheel in vacuum enclosure with magnetic levitation bearings might solve the main issue with renewable energy sources as a cheap and reliable energy storage.
Important to know, that not only the mass is important, but its distance to rotation center. Both flywheels could have the same mass, if one has its mass mor far from the center it will have a higher moment of inertia
Hi bro, fly wheels are the best creation ever using Lego. I also have a suggestion for you, you should make a suspension mechanism and equip it in the testing mechanism,the main purpose of it is to pretend the damage to the "weight", I've noticed that when you release the clutch while the elevator is at it's maximum altitude, it falls and breaks, and this may cause damage to the Lego parts Thanks for reading bro, I appreciate it❤️
Hey there thank you so much for the that i appreciate it! That’s a cool little idea I like it. I do love flywheels too I have a good little test soon and will use one on a Lego saw as well :)
@@shlushe1050 well... I don't think so, a ratcheting mechanism won't absorb the shock, it'll just hold the elevator up and prevent it from falling, but how will we get the elevator down after that?
@@abossoum2392 that's the point lol, after it goes up it'll hold itself up showing how efficient it is at transferring power. Then to release it you can release the holding lever, ratchet and tooth
Welcome back my man!! Hope you’ve been well!! Very impressive fly wheel technique! I did not think it could hold as much weight as it could🤣 I wonder if you tried some how making a new system with multiple disks like on a real manual car, that would be very interesting! Cant wait for more vids!
Hey Easton I searched for your name on replies but it didn’t show! Thankyou very much as always! I’ve been well thankyou, a few around me not so which I think had some effect but I’ll be busy busy from now on :) Great to see you about 😀
Nice work. If you measure the height of the lift it's easy to calculate the energy transferred. If you also measure the speed of the flywheel then the transfer efficiency can be approximated
@@GazRsExtremeBrickMachines I can help with that! The energy stored in the flywheel is 0.5 x I x w^2, where I is the moment of inertia and w is the rotational speed ( in radians per second (= rpm / 60 x 2π)).

@@sammason2300 that’s great info thank you so much! With a working clutch I have confidence it can do much better haha. I really appreciate the time for that reply cheers Sam :)
I'd suggest adding a gearbox to increase the torque on the lifting end to avoid the clutch slipping, and possibly adding in another flywheel there too to provide a more controlled decent when the load comes back down which could be engaged with a ratchet.
@@glowytheglowbug hey thankyou, honestly my knowledge on Lego clutches is limited at best! Lol. I wanted a smooth transition but a locking one would have been better :)
@@GazRsExtremeBrickMachines ooh i gotcha ive tried clutches before too on my large battlebot lol still cant find one that dosent have crazy amounts of friction when there is force on the axle would be cool to see what you can come up with!
@@glowytheglowbug yeah it’s near impossible I think as there’s always something pressing against a beam. I found a way to take it off the input axle which you’ll see in a few videos time but the flywheel is still rubbing on the far side. I do use oil which really helps! I found olive oil lasts longer than certain sprays. :)
Hello nice to see you back. You should try making 3 more of those 2.8 kg flywheels (if you have enough parts) and see what happens when you put them on a car. You might need brakes on that car.
Haha hey Donnacha! Nice to see you still around thank you! You would need big brakes lol, I think I used two thirds of my panels! There’s a crazy amount in there. Think 300 plus eek
Hey Gaz long time no see. Glad you're building again. I like this, it has a real sense of power and threat! sort of reminds me of Event Horizon. Very nice build as ever. As for the clutch, can't you do an intermediate gear ratio of say 3/4 which then gives you 25% more torque handling? or you could double up on clutches? Lovely build. And pretty unique to Lego 👍🍺🇬🇧
Hey cheers Carl it’s been too long! Originally I had no clutch but I couldn’t keep tension in the slack line well enough and then it wanted to destroy itself when it hit the top lol. I think the gearing would help but I’m hoping to pull or lift a lot lot more! I know you’ll know so much more about Lego clutches than me, I think this is my first! 😀😀
@@GazRsExtremeBrickMachines oh I get it now. Why not use a differential as torque sensor - when it hits the stops, the torque rises rapidly and the diff operates a cut off switch and disengages drive. Not a million miles away from the auto geabox thst @MaxBrix and others did. I know little of Lego compared to you! 'tis great to see what other people come up with. Now RC cars.... there's some good stuff there and I bet you're just a few moves away from getting into that as well. Take care 👍🍺🇬🇧
I’m still trying to keep away from RC! I love your 4x4 crawler so much! Thanks for the info Carl I really do need to learn a bit more on this! It’s weirdly one thing I never played about with much when I was younger. 😀🍺
Maybe on the clutch side you could have some way to slowly lower the weight without hindering the lifting of said weight. Like some kind of escapement. So you don't have a weight crashing down to the ground.
2:13 I could be totally wrong about the answer for this, but with some basic math problem solving: based on the weight difference of the biggest flywheel and the one before it as well as the weight of the final load test for the second last flywheel, the potential maximum load weight for the big flywheel could be around 12.4 kg or about 27.3 lb, which is also about 4.4x heavier than the flywheel itself. It would be pretty impressive if my guess here is close to the end result. You'll definitely need to enlarge and/or reinforce the clutch first though like you did with the flywheel. Otherwise, the clutch will always limit the potential maximum lift height. I think.
it seems to convert energy to friction at connecting the clutch. so maybe it is good to add CVT beside the clutch’s input . connecting the clutch, set input low and output high. after connecting the clutch, set input high and output low. (i’m japanese student. so i maybe make a misteke of words.)
Def get rid of the friction clutch, and try a multi geared transmission. Yes, a pain. But would be cool. That way can multiply the force of the flywheel some more.
Hey there thank you for that I think I will get rid of the clutch, I’ll play about with things. The big problem is getting things to handle the torque :)
Wow, that's some extreme engineering! Nice! Yesterday I uploaded a video from my new Technic Train Elevator. It lifts around 5-6KG with one large motor, with counter weights. What do you think?
Hey there I will watch that later and thank you very much, I love your trains so much! I hope you have the views you deserve now, I’ve been away from RUclips for quite awhile :)
You gotta use more friction square, like in clutch mechanism in car gearbox and decrease the gear ratio in lifting mechanism, so it will be slower, but effective.
flywheels are really neat. the earliest electrically powered bus i know of used a flywheel and an electric motor. the motor spun the flywheel up to speed when at bus stop through an overhead wire connection when t the stops
Oh wow thanks for that info! It’s scary how much energy big heavy flywheels can hold! Although my experiment didn’t show it too well lol :) I know the lmp1 cars a few years ago had flywheels where a passenger seat would usually be and spun up during braking by electric motors and then released the charge back to the front axle at the corner exit.
I wonder if instead of using a friction based clutch, you could instead use a series of pegs which slot in. The plus side is that there is no slipping. But the downside is that there is absolutely no give - It's either all or nothing system. The alternative is to use more friction material, or increase the pressing force between the friction material.
could you change the gear ratios between the clutch and the load? That way you can still measure the energy in the fly wheel (it’s ability to lift the load), while reducing the required friction on the clutch. The transfer of energy will just be slower, that’s all.
waow, a new vid! ive always wondered if you could get infinite energy from a flywheel by powering the center and setting up an alternator pulling energy from the outer edge of the flywheel
Hey there I kind of wanted to try this but the nylon kept binding too much producing a lot of friction which didn’t help. I’m sure with a proper set up you could store quite a lot of energy like that :)
Hopefully it will not be another 6 months for your next vid.. I've learned from Dan and Rob at Vidiq that subs will come and go over time. But your your true fans will stay as long as you're releasing content.
Hey there thankyou very much, I’m just filming the next one :) I think what I’ve learnt is if the content clicks the right boxes a video will usually do well. More subs equals a better starting point which is a great help but over time a video will do well whether you have 1000 subs or 100,000. I’m so surprised to see so many familiar profiles which is great 😀
Hey yes they do they’re fascinating things! I stayed at a hotel which spun a flywheel under cheap rate electric and released the energy during high rate! :)
You could have taken a current diagram while accelerating these flywheels and if you'd powered the motor from an lithium battery you could see why flywheels have no participation in energy storage... How often is your setup flown apart in pieces? Seems wobbly, but I am sure you have built it as sturdy as possible...

Hi
Hello there! I have one idea for you to try- if you could attempt on making Mars rover type of vehicle- 6x6 or maybe 8x8 drive with some insane suspension, and also maybe a claw to lift some stuff and put into some type of a bow on that vehicle.

Thankyou very much! they’re fascinating things, I really wanted to push it more, next time hopefully :)
Theyre good weapons too if you put 2 teeth on each end of them
Actually they can’t hold that much energy. The chemical energy stored in an equal mass of gasoline could do this lifting for hours or even days.
@@Mike-oz4cv I know, the fact that it can even lift the weights is impressive. I wouldn't expect it to get off the ground.

@@GazRsExtremeBrickMachines im doing great. all I can say is you are the best!
Awesome video!
Thank you very much Peter :)
Ayyyx King is back
Hey there that means a lot, cheers😊
@@GazRsExtremeBrickMachines remember me? Like maybe as Lord_Backfisch? Or boiledtea? (I got a new Account on my PC so this is my mobile account now
Of course I remember you (that name) you always commented! I do like a cup of tea so won’t forget this one lol :)
@@GazRsExtremeBrickMachines :D
Nice work. If you measure the height of the lift it's easy to calculate the energy transferred. If you also measure the speed of the flywheel then the transfer efficiency can be approximated
I was hoping someone would explain how to work it out :) The energy always surprises me.
@@GazRsExtremeBrickMachines I can help with that!
The energy stored in the flywheel is 0.5 x I x w^2, where I is the moment of inertia and w is the rotational speed ( in radians per second (= rpm / 60 x 2π)). The moment of inertia depends on the mass distribution through the flywheel, but for a solid disk is 0.5 x Mass x radius^2.
This energy is then transferred to gravitational potential energy, which is calculated as the mass of the load (in kg) multiplied by the gravitational constant (approx. 10m/s/s) multiplied by the vertical ascent (in metres), i.e. energy (in Joules) = m x g x h. In your last case before the clutch gave out the machine lifted 1kg by about 50cm (guess) so that gives 5J of energy output.
The efficiency of conversion is simply the ratio of these two energies.
P.S. don't be disappointed if the efficiency looks quite poor!
@@sammason2300 that’s great info thank you so much! With a working clutch I have confidence it can do much better haha.
I really appreciate the time for that reply cheers Sam :)
@@sammason2300 hey could you copy paste that as a new post if you get chance! I will pin! People like this stuff :)
watching that huge flywheel spinning and making the whole contraption wobble gave me severe anxiety
I'd suggest adding a gearbox to increase the torque on the lifting end to avoid the clutch slipping, and possibly adding in another flywheel there too to provide a more controlled decent when the load comes back down which could be engaged with a ratchet.
Hey there that’s a great suggestion! Thank you so much, the second flywheel is a great idea!
Spin the flywheel faster with higher gearing/more robust/powerful motors for the next video! :)
Awesome!
Hey thank you very much! I’ll definitely use more motors next time, it could get interesting… lol :)
super cool! great build as always :D
Thank you very much it means a lot :)
@@GazRsExtremeBrickMachines you have a great talent :D also is there a reason to use friction clutches in the engaging
@@glowytheglowbug hey thankyou, honestly my knowledge on Lego clutches is limited at best! Lol. I wanted a smooth transition but a locking one would have been better :)
@@GazRsExtremeBrickMachines ooh i gotcha ive tried clutches before too on my large battlebot lol still cant find one that dosent have crazy amounts of friction when there is force on the axle would be cool to see what you can come up with!
@@glowytheglowbug yeah it’s near impossible I think as there’s always something pressing against a beam. I found a way to take it off the input axle which you’ll see in a few videos time but the flywheel is still rubbing on the far side.
I do use oil which really helps! I found olive oil lasts longer than certain sprays. :)
Love it. Would be cool to have a couple gears to go through to spin up the flywheel:)
Very nice. Like, comment share...😃
Hey thank you very much :)
Man putting your cat in that last flywheel really did the trick lol
Lol he’s quite a big guy as well, 7 KG! Lol
Hello nice to see you back.
You should try making 3 more of those 2.8 kg flywheels (if you have enough parts) and see what happens when you put them on a car. You might need brakes on that car.
Haha hey Donnacha! Nice to see you still around thank you!
You would need big brakes lol, I think I used two thirds of my panels! There’s a crazy amount in there. Think 300 plus eek
Hey Gaz long time no see. Glad you're building again. I like this, it has a real sense of power and threat! sort of reminds me of Event Horizon. Very nice build as ever. As for the clutch, can't you do an intermediate gear ratio of say 3/4 which then gives you 25% more torque handling? or you could double up on clutches? Lovely build. And pretty unique to Lego 👍🍺🇬🇧
Hey cheers Carl it’s been too long! Originally I had no clutch but I couldn’t keep tension in the slack line well enough and then it wanted to destroy itself when it hit the top lol.
I think the gearing would help but I’m hoping to pull or lift a lot lot more! I know you’ll know so much more about Lego clutches than me, I think this is my first!
😀😀
@@GazRsExtremeBrickMachines oh I get it now. Why not use a differential as torque sensor - when it hits the stops, the torque rises rapidly and the diff operates a cut off switch and disengages drive. Not a million miles away from the auto geabox thst @MaxBrix and others did.
I know little of Lego compared to you!
'tis great to see what other people come up with. Now RC cars.... there's some good stuff there and I bet you're just a few moves away from getting into that as well. Take care 👍🍺🇬🇧
I’m still trying to keep away from RC! I love your 4x4 crawler so much!
Thanks for the info Carl I really do need to learn a bit more on this! It’s weirdly one thing I never played about with much when I was younger. 😀🍺
Definitely need more support in the frame, especially where it lifts the weight but overall really cool
Maybe on the clutch side you could have some way to slowly lower the weight without hindering the lifting of said weight. Like some kind of escapement. So you don't have a weight crashing down to the ground.
Hey yes nice idea, I needed a double clutch when one engages the other disengages maybe :)
2:13 I could be totally wrong about the answer for this, but with some basic math problem solving: based on the weight difference of the biggest flywheel and the one before it as well as the weight of the final load test for the second last flywheel, the potential maximum load weight for the big flywheel could be around 12.4 kg or about 27.3 lb, which is also about 4.4x heavier than the flywheel itself. It would be pretty impressive if my guess here is close to the end result. You'll definitely need to enlarge and/or reinforce the clutch first though like you did with the flywheel. Otherwise, the clutch will always limit the potential maximum lift height. I think.
Thank you very much for this comment! Sorry I’ve been away and logged out. I’m continuing with the project shortly :)
it seems to convert energy to friction at connecting the clutch. so maybe it is good to add CVT beside the clutch’s input . connecting the clutch, set input low and output high. after connecting the clutch, set input high and output low. (i’m japanese student. so i maybe make a misteke of words.)
Hey there that’s a very interesting idea thank you for that! Your English is great too :)
Def get rid of the friction clutch, and try a multi geared transmission. Yes, a pain. But would be cool. That way can multiply the force of the flywheel some more.
Hey there thank you for that I think I will get rid of the clutch, I’ll play about with things. The big problem is getting things to handle the torque :)
Welcome back
For the left side, you could use a clutch that starts by contacting Rubber (like now) but After that also inserts physical pins (like the right One)
Hey thanks for the idea it’s much appreciated :)
Would recommend adding more rubber pads on your clutch, and if that doesn't work, make it bigger or have more pressure.
Hey there thank you for that! A bigger clutch would help hugely! Also my rubber studs have gone a little dry which didn’t help :)
Yay he’s back
Wow, that's some extreme engineering! Nice!
Yesterday I uploaded a video from my new Technic Train Elevator. It lifts around 5-6KG with one large motor, with counter weights. What do you think?
Hey there I will watch that later and thank you very much, I love your trains so much! I hope you have the views you deserve now, I’ve been away from RUclips for quite awhile :)
You gotta use more friction square, like in clutch mechanism in car gearbox and decrease the gear ratio in lifting mechanism, so it will be slower, but effective.
Never heard of a flywheel but pretty cool
flywheels are really neat. the earliest electrically powered bus i know of used a flywheel and an electric motor. the motor spun the flywheel up to speed when at bus stop through an overhead wire connection when t the stops
Oh wow thanks for that info! It’s scary how much energy big heavy flywheels can hold! Although my experiment didn’t show it too well lol :)
I know the lmp1 cars a few years ago had flywheels where a passenger seat would usually be and spun up during braking by electric motors and then released the charge back to the front axle at the corner exit.
@@GazRsExtremeBrickMachines oooo, nice that is another cool use of flywheels.
you should add a ratchet gear for the clutch and put a limiter to not crank past the top
I wonder if instead of using a friction based clutch, you could instead use a series of pegs which slot in.
The plus side is that there is no slipping. But the downside is that there is absolutely no give - It's either all or nothing system.
The alternative is to use more friction material, or increase the pressing force between the friction material.
could you change the gear ratios between the clutch and the load?
That way you can still measure the energy in the fly wheel (it’s ability to lift the load), while reducing the required friction on the clutch.
The transfer of energy will just be slower, that’s all.
Hey Aaron I should have done this tbh. I was worried it would lift to slow but it would have been ideal. Cheers :)
So cool 😎 👏🏻!
waow, a new vid! ive always wondered if you could get infinite energy from a flywheel by powering the center and setting up an alternator pulling energy from the outer edge of the flywheel
Hey there I kind of wanted to try this but the nylon kept binding too much producing a lot of friction which didn’t help. I’m sure with a proper set up you could store quite a lot of energy like that :)
makes sense
awww the cute cat😄😄
Cheers I’ll pass him the compliment :)
While lego stuff surely is interesting it was the cat I appreciated the most.
Finally thank you very much
I love your cat😊
Hey thanks I’ll pass it on :)
Came for the Legos, stayed for the Charlie :) also...I wish I had enough money to buy all these Technics!
I wish you did! Awe thank you, he stayed with me till 7am the next morning whilst I finished filming and editing. :)
there was a bus made out like this, but he converted the rotational energy into elecricity with magnets and cooper, try something like that.
Hi there I’ve read about the buses using huge flywheels, fascinating stuff. The energy is immense!
You could probably make the flywheel even heavier by putting pins through all the holes.
The thought scares me lol. But yes every little helps :)
that is so cool
Hey thank you very much :)
@@GazRsExtremeBrickMachines 👍
Hopefully it will not be another 6 months for your next vid.. I've learned from Dan and Rob at Vidiq that subs will come and go over time. But your your true fans will stay as long as you're releasing content.
Hey there thankyou very much, I’m just filming the next one :)
I think what I’ve learnt is if the content clicks the right boxes a video will usually do well. More subs equals a better starting point which is a great help but over time a video will do well whether you have 1000 subs or 100,000.
I’m so surprised to see so many familiar profiles which is great 😀
Yes👍
Wow, nice👍🤣🤣
Hey Naveed! Thank you 😀😀
I'm pretty sure some wind and solar farms use flywheels in vacuums for energy storage
Hey yes they do they’re fascinating things! I stayed at a hotel which spun a flywheel under cheap rate electric and released the energy during high rate! :)
Super cool that nice job
Thanks Ian much appreciated :)
When you said "and Charlie" for a split second my brain thought you were gonna spin a cat 💀
when ur clutch becomes a brake = / cool concept for sure
Hey thanks Erik, more work needed on the clutch :)
You could have taken a current diagram while accelerating these flywheels and if you'd powered the motor from an lithium battery you could see why flywheels have no participation in energy storage... How often is your setup flown apart in pieces? Seems wobbly, but I am sure you have built it as sturdy as possible...
Perfect example of destroying your clutch. XD
