@@davidepiccini9254 Hi, Davide 😁

@spencer963 I try to get a video uploaded here every couple of weeks to keep the channel ticking over 😁👍

Sorry for the late reply, TH-cam hid your comment. 0345 is the number of the video. All the videos on this channel are numbered in sequence. The rubber bands I used came from Poundland. If you are not in the UK that won't help you, but they are just cheap ones from the bargain store. Dollar Store if you are in the USA.

@rabiasyed1808 potential energy is the cake in a box, kinetic energy is eating the cake. Potential energy is stored in the rubber band when you stretch it. Kinetic energy is the band returning to normal.

No, back in 2015 that wasn't a regular part of my videos.

@@DontPaniku This is true.

🤣🤣

I have no doubt you could, but that wouldn't qualify 🤣🤣👍👍

@@Putarubberbandonit 🤣 definitely wouldn't

Hi, Allan. I hope you are well 😁😁👍👍

@@Putarubberbandonit doing eggscllent here greandad.

Thank you

@motherisape Yes, but there is a trade-off. You lose some power due to the friction of the bearings and gears. Obviously, if money is no object, you could invest in proper bearings and low friction nylon gears. If you have a single band and you want to maximise the stretch without wrapping it around the axle, use a long chassis and use string to go from the band to the axle. That way, it is the string that goes round the axle, and none of the band stretch is wasted 👍

@motherisape yes, I am living the dream 🤣 In fact, I uploaded this to the wrong channel, but I left it to see if anybody noticed. Normally, they are a daily upload to my GrandadIsAnOldMan channel 👍

@@Putarubberbandonit I used to watch that channel long ago it was one of my favorite channel

@@motherisape well it is still there, but I put the rubber powered stuff on this channel 😊👍

Thanks, Marc 👍👍

Fast is mainly about power and grip. Plenty of rubber bands for power and rubber tyres for grip. If the tyres wheelspin then you are just wasting the power. You can also add weight to the back of the car to help the wheels grip. Small wheels will give you faster acceleration. Large wheels will give you a faster top speed but take longer to get there.

Here are some thoughts on fast cars - with related links in the video description th-cam.com/video/yIkUHWcQKrA/w-d-xo.html

Thanks. The problem is I am trying to clear stuff out and instead of that I find stuff and do new projects 🤣🤣

Do you mean, "how do I join the rubber bands together?" - Helpfile - Joining rubber bands together th-cam.com/video/EbYuhdwknbs/w-d-xo.html If you want to spend more money, you can buy proper hobby grade rubber used for competition rubber powered model aircraft. You buy that by the yard or meter lengths. That is what I am using in this video. If you mean the propeller assembly, that one came from another rubber powered plane kit.

@@Putarubberbandonit what rubber band plane kit I would like to maybe get that

@@spencensawyersmom any cheap "wooden stick" rubber powered plane kit would have the propeller assembly, sometimes they turn up in the shops as seasonal stock. Or you would have to search online. I have a couple of playlists on making rubber powered planes (the links are in the video description, but I will put them here for you.

@@Putarubberbandonit thank you

That is interesting. It seems to be a problem with Tinkercad. I just tried it myself and it failed, then I created a duplicate file and tried that and the download failed. I have just uploaded it to Thingiverse and that seems to work www.thingiverse.com/thing:6769556

Hang on. That has just FAILED too. I will see if there is somewhere else I can put the STL file. Give me a while to work on it 🤔🤔

Right this direct Thingiverse link seems to work for me www.thingiverse.com/download:14757960 PLEASE LET ME KNOW IF IT WORKS FOR YOU

I have uploaded a fresh file to Thingiverse and that seems to work www.thingiverse.com/thing:6769692

@@Putarubberbandonit ok thanks so much

@@MsRaidman that is how 3d printers work. They build the item in thin layers. However, when it is that thin, there is a good chance it will tear when you are lifting it off the print bed.

I was just gentle winding it up. I went as far as I dared 😁 If I was going to try it over a longer distance, then I think it would need to be a bit stronger, but in the bath it was good enough. I squeezed the video into portrait mode, so you can't tell how far it goes, but the length of the bath is well below it's capabilities.

That depends on how you define "working". It flies a bit, but it is not likely to disappear into the distance miles away. Not every configuration works, some work better than others. It is intended to help you learn about trimming the settings and trying different layouts to see what works best. If you don't try, you will never know.

Hi, Lynn. Yes, larger stiffer rubber bands would give it a faster burst of power. However, soft hobby grade rubber as used in model aeroplanes would allow more turns so it would run for longer. A more aerodynamic propeller would help, too. The difference in wheels is demonstrated in the video. The toy car wheels certainly reduced the distance travelled👍

Thanks, inspired by the kits I could see on eBay. With proper rubber it would probably go further. Those cheap rubber bands are "cheap" 🤣🤣

I did try a different propeller that I had laying around, but it didn't improve the performance so I didn't include it in the video 👍👍

I was disappointed, I thought it would go better.

Just soft plastic 👍👍

I thought I would do a few simple basic cars with no 3D printed parts and no special tools.

I usually just save the batteries from vapes, but when I noticed these I instantly thought of car tyres

Thanks 😊😊

When I saw these parts in the vapes I wanted to do something useful with them.

@JustFun-iz9rf Yes, I use Tinkercad for all my 3d designs. It is free to use. In effect, you create things by putting together basic building blocks.

That would be something you would find out when you try it. It would depend very much on what weight you use for the swinging ball. The mass gives you the inertia. The other 3 balls are more or less just for visual effect.

@@Putarubberbandonit Thanks

@@LarryReedVT it made me smile 😁

@@horrido666 This is not my design. I just downloaded it from Thingiverse 👍

@spencer963 once it started to loosen up, it was running fine. Silicone spray worked well as a lubricant 👍

I was pleased I managed to get it running. I was beginning to think it wasn't going to work.

@@RaakeshV it was cheating, taking Cds with me on holiday. I have used beer mats/coasters for wheels in the past 🙂

@@Putarubberbandonit Beer mats for wheels? That's some next-level engineering! I'm guessing the car runs on lager fuel too? 🍺🚗
