The main issue will be getting enough grip from your wheels, so you will probably need rubber tyres. Next point will be gearing. You don't necessarily need a gearbox, although that would help you get more power to the back wheels. Instead of a gearbox, you can use relatively small wheels and a relatively large axle to wind your rubber motor round. The bigger the diameter of the axle, the "lower" the gear you are in, so the heavier the object you can pull. I did this video on the maths back in 2015 kzbin.info/www/bejne/fn_GcmNqpM95ZtU

@mikeflight9 Hi Mike, dull and grey outside at the moment. It is probably better suited to balsa gliders or at least any glider with a reinforced fuselage to take the strain 😊👍

@Sea-Dog5496 probably more effective to put a stiffening rod along the length of the plane👍

@@Putarubberbandonit Great idea. Shove a stick up its rear. I know some people I would like to try that on. 😋

Haha, KZbin hid your reply, they thought it might be offensive 🤣👍

@@Putarubberbandonit I take it you could not read it? No matter. It was a little off color. I am not surprised. I try to be discrete, but I don't always get away with it. Haha

@Sea-Dog5496 I always check the "held for review" folder. If I didn't, I would miss half the comments. KZbin algorithms tend to catch innocent comments and miss the important ones. My 9pm publications on my main channel always get a comment from an automated porn bot. It is a new one every night, the bot creates a new channel and spams publications with seemingly harmless comments, but the thumbnail is the same each time and the channel is simply a link to an external porn site. As they use the same images every time, I cannot understand why KZbin can't write an algorithm that spots it as soon as it is created and blocks it immediately. A cynical person might think KZbin is happy to play along with it as it will make their stats look good with new channels created every night to boost KZbin's numbers.

🤣🤣👍👍 Good morning Mike 😊😊🌞🌞

@spencer963 Haha, spoken like a true American, you can never have too much power 🤣 Sitting drinking my coffee watching the world go by. Frosty start this morning, but the sun is shining 🌞

@Putarubberbandonit hell yeah! Don't need to be getting locked up for posting a meme 🤣 though admittedly, our government was getting too far out of hand. Next 4 years will be better :)

Hi Ed. There is another video tomorrow with some replacement rubber bands. I did this video about a week ago, but scheduled the publication for today. Since then I have been hunting for suitable replacement bands. I could order them online, but I was hoping to find some in local shops. It looks like the size of rubber bands I wanted are no longer stocked anywhere. Then today I found I had a box of suitably sized ones in my own stock.

I am sure you could if that is your preference. I prefer to avoid weapons on my channels 😁😁👍👍

I assume you are talking rubber band powered. I would guess you would need gearing to make a reverse feature. I vaguely remember a toy mechanism with 3 gears where the "middle" gear only engaged in one direction. The gear shaft rode in a slot and one of the other gears must have too, so the outer gears engaged for forwards, and the third gear dropped in for reverse. In a similar, but different, gearbox on some pullback toys they have an action to wind up the spring when you pull it back, and engage an extra gear when it drives forwards

@KingdomCome811 there is one way for you to find out 😁 Build one yourself and try the various combinations and options 👍

Thanks, yes, running it hotter seems to be doing the job 👍👍

@Putarubberbandonit what do you set your build plate to? I'm constantly using 65c

@@spencer963 I pushed it up just a touch, currently running 68°C It is a glass plate with a coating that is supposed to grip the print while it is hot, but when I am having problems I often add a layer of Elmers glue.

By coincidence, tonight, I was searching for some brass tubing in my "stock room" and came across the wooden launcher and thought I might give it another video for comparison. So you will probably see it again, fairly soon. It just needs a few replacement bands as the old ones have gone brittle

😁😁

@@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, KZbin 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 kzbin.info/www/bejne/r3rOhnuNmLZ-qKM

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 kzbin.info/www/bejne/e5O8ppuarNChmNU 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.

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 🤔🤔

@@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 👍👍
