ALLWAYS

I love the camaraderie amongst Engineering UKposts! Thanks for all you do Destin!

No

It’s just amazing, I could see people in a future society making these and using them for communication or transport, the clean energy and easy production is such a necessity for creative ideas in developing countries.

Absolutely

But thoroughly useless like all of Tom’s projects. If he turned his mind to solving task that actually need solving, I’m might find it easier to accept him as a fellow human. However, with that hair colour and his current penchant for making less than pointless objects, Ginger Tom can S a F.

My hand gets sore pretty quickly if I have too much crank time 🌈

Makes me think it'd be sweet to make it a treadle charger instead of hand crank and make a second battery pack. UNLIMITED POWAAAAHHHH!

I use a 1S lipo for radio and servos - runs to 3.3 volts on all my AM yacht and 2.4gHz Flysky gear. Suspect the ESC sets the limit and may be resettable.

Why schottky diodes? What do they do?

It's also safer then handing a bunch of kids a lithium polymer battery.

I used to have an old super capacitor plane, air hog thing. it was amazing. I havent seen one in years though.

Yeah its good with the short charge time cus kids these days have got the attention span of a flea 😂

i think it forces the kids to crash the plane multiple times to recharge the thing.

@@Darkknight512 they use nicad batteries for kids stuff. a lot more stable then lithium for less energy density, and dont pop like copasitors.

Same, would be an awesome kit to play with!

totally impressive. thinking where we were 35 years ago

Can we buy the stl files for this build ?

Yes, this is so cool❤

Only thing that comes to my mind in a way of improving it is a way to ride a bike to the field and use the bike somehow to crank the generator!

Would be cool if it could do this automatic. Meaning that if you do this just a bit before the motor would die it would extend your glide time.

Doesn't ESC braking require a holding charge though? When out of power to run the motor, the braking may not work either.

I guess you only need to brake shortly as after the props fold they won't spin out again

Yes, but once the motor stops and props fold in, it wouldn't take much. Almost all plane ESCs have this feature built-in. @@Alluvian567

​@@Alluvian567 if you do it right before by having a volt meter or low-voltage trigger on-board, it can do it right before. It only needs to brake for maybe a second, then the props will come in, and as long as it isn't turning too sharply or nosediving at low speeds, the force of the incoming air will hold them back with very little added drag.

FOOL BRIDGE RECTIFIER

@@tyty_5869😂😂😂

Tom will have to do some Mehditation for that hehehe

He just showed up

Before Tom even said it, I had Mehdi's voice in my head 😂

From an engineering perspective, though, I do wonder whether the plane really pushed even 100W during operation. As an example, running those supercaps at the same power density (per gram) as the lithium battery, they'd run from full charge to zero in about 12 seconds. Also, checking the charging, seemed like it took about 90s to charge the capacitors to half voltage - that's a quarter of their full energy capacity, so the crank power output was (0.125Wh * 6 / 4) / 90s ~ 7.5W over the duration, which is well below the charge rate of even one lithium battery. Not saying a supercap plane isn't awesome, but it does help illustrate why lithium batteries are in such high demand - they really have great power/energy characteristics.

I believe Tom is also an engineer.

He is an aerospace engineer

I also love his channel. There are many brilliant makers here. Another amazing one is Shane from @StuffMadeHere - a ton of engineering, programming and crazy ideas. Wonderful fun with electronics can be found @greatscottlab And if you are interested in various forms of generators, batteries and amazing humour, Robert Murray-Smith from @ThinkingandTinkering can be your guy 😊

Right? I was amazed how clean the capacitor bank looked!

agree!!

Yes i just have rubber ones or slingshot type planes

Why didn't he just use a brim or raft to get better build plate adhesion and integrate the batter and wire connectors into the design to save weight?

The brake requires power. Motor stopped from no power

@@spudjames5038 motor stopped because ESC measured voltage below minimal cutoff value set in parameters, even old typical 20A ESCs have its settings accessible via throttle movement on startup and counting beeps of the engine, very nice to lower down cutoff value after switching to Li-Ion instead of Li-Po battery chemistry. Also could be desirable in this scenario when we want to drain capacitors as much as possible. Also ESC brake is done by shorting motor coil terminals through mosfets on high side or low side, it does not consume power from battery or capacitor source. Just like when you touch the two wires coming out from DC motor and try to spin it by hand, you will feel braking force.

He needs to make this where the wings fold in, and the V tail into an X tail, so he can rocket it up to altitude and then glide back down..

Use a diode and a separate supercap to power the RC controls, this way they will retain power longer than the motor and allow you to set the ESC cutoff voltage lower and get more flight time.

Stop the Prop by Pulling Up into a momentary Stall, Prope should back and stay there.

@@HoundDogMech Именно так.

On most electronic speed controllers (ESC) like what he used in this project there is a setting called "brake". As soon as the ESC senses a rotation, when zero rotation is commanded, it applies a small reverse current to cause the motor to stop spinning. I have used it on many glider airplanes with folding props. Occasionally, like you mentioned, you'd have to blip the throttle to get the prop stopped in the ideal position.

@@Carrera0to60 In the case described by the author of the video, the option with electronic engine stop is not correct. The charge of super capacitors is very small, and when they are discharged there is no way to do this correctly. But you can try to make an electromechanical stopper. It is necessary that it be turned on all the time while the engine is running, and when turned off, it blocks rotation. I would try to make something similar from a small relay or solenoid. It will, of course, consume some energy, but it might be worth a try. In the case of a rubber motor, the rubber band with stored energy pulled the propeller axis more strongly towards itself. When it had completely used up the energy reserve, at this point, the rod no longer pulled so much, and under the action of the spring it moved forward, where it touched the adjusting bolt.

Those competitions still very much exist, flight durations are over 40 minutes now

wow!

This video is a shameless clickbait. Tom Stanton has no respect for his viewers and them are so smart that they forget what they were sold in the thumbnails. Probably no dignity either to mind it if they noticed.

@suprememasteroftheuniverse he literally does that all the time though. Yeah, 6 capacitors arranged to look like a radial engine would have been cute, but it would have suffered catastrophic failure from the one thing he specifically designed the real plane to be able to survive.

​@@suprememasteroftheuniverse"Clickbait" implies the title and thumbnail promise something not shown in the video. Sure, the exact thumbnail doesn't show up in the video, but you didn't click on this to see the thumbnail, because you already did. You clicked on it because you wanted to see a "Super Capacitor Plane", which _was_ shown in the video.

And it working very well on the first try

I love both of your videos, glad to see you here BPS

You won’t

Hi joe

It would be a cool idea for you to make a air launched rocket that launches off of a plane

Rocket launch via drone or drone launch via rocket would be pretty cool

I was thinking the same. Something like a joule thief would be easy to implement.

A SEPIC converter would be nice here. These days they can get an efficiency of around 85-90%. Using some schottky diodes also helps.

Boosting such low voltages is quite inefficient, and the last 5 volts anyways contain only 10% of the total energy of the full 16V. (The crux is that the lower the supply voltage, the more current you need to draw for a given power requirement.) So, this isn't worthwhile.

@@FlyGamingChannelIt don’t think it would work, unfortunately, as a joule thief’s boosted charge immediately collapses in the face of any significant loading.

Maybe even regenerative propeller movement.

Honestly, that's a hilarious thought. I wonder how long it would take for an airliner filled with pedal cranking passengers to be able to launch the plane into the air by hand power alone. it would probably make it easier to fall asleep on the plane afterwards lol.

That's great, but for cost savings and the fact that smooth current for charging isn't needed, single phase is fine. Furthermore while 3 phase uses 6 diodes, a bridge rectifyer uses 4 diodes but one can reduce the part count to two diodes and use half the turns of copper coils if they make a Delon Full Wave Voltage Doubler with two diodes and his supercapacitors. Maybe with the money saved, one could splurge and get six 2.9v zener diodes as a rudimentary capacitor balancer to prevent over charging unballanced capacitors.

You don't need filter caps when all you're worrying about is charging up capacitors lol

You don't need particularly clean DC when charging caps.

Is that what it is called?

@@Maxim.Teleguz boost or step-up converter, yes.

The wide usable voltage range from 18 to 6.5 or 5 volts negates the benefit of a boost converter. You might end up getting less in the end, definitely not worth it.

@@celeron55 The thing is that capacitors are totally fine with being discharged all the way down to 0V. So discharging from 18V to only 6V means you still have 33% of your energy left in the caps. If a boost converter has better than 66% efficiency (and weighs a negligible amount) it would improve run-time. Anther option could be to use more caps in series and go all the way up to 48V or so (maybe with a step-down converter to ~18V if your components can’t handle 48V directly). That way the 6V cut-off means you only lose 12%.

I like this idea, squeeze all energy from these caps. But there are some voices against it. Maybe a Joule thief to save on weight?

Might start a fire on the plane though

@@FilmLadd Oh good point. He'll want some nice fire-retardant coating. :)

@FilmLadd not only a plane, but fly-by birds. From the other hand: fly plane endlessly and munch some fried chic... ehm, pigeon ;)

It could work, but it's also a great way to get the UK equivalent of the FCC *very* angry.

ok, then do it, you have books you have questions, go read and ask.

​@@osmacar5331I know you're trying to encourage, but this came off as smarmy and condescending

Don't forget the added weight

@@crackedemerald4930 yup, this is true

Tom's calculation is that the energy in the caps is about the same as a coin cell. I'd assume you only would add seconds of run time with a boost converter. Not to mention it needs to be light and high current.

And you'd lose control authority very quickly after engine failure.

@@merseyviking Oh yea, that'd be the real nail in the coffin.

that's hours of cranking one battery. You overstimate human's "im tired" at just 5watt production after 10 mins.

he should repurpose one of his bikes as a generator lol@@dimitar4y

@@ilovehumongoushonkers he can but thousands of people already did it on youtube and it's not worth it

@@dimitar4y Realistically it's only about 10 minutes of cranking to fill up a battery. If the battery holds 10 watt hours and the crank is capable of producing 50 watts.

@@DKFX1 where's the losses, bud.

you should be able to program the ESC to apply a brake when you stop the motor .

Using the motor as a generator to recharge the capacitor could get extended flight time if you initially go really high and then want to do a bit more low flying at the end - whilst your ideas would optimally extend gliding I believe having throttle control on landing could be more useful and fun in most cases. A switch between braking and regeneration would be even better although it may be heavy to implement both.

Don't think they could learn from UKposts video?

Yea, he absolutely nailed it on this one.

There isn't even a motor in the thumbnail. It's just a thing he printed so he could stick the capacitors in the nose for the clickbait.

@@CYDeviant Lol I wonder if it is worth it since the original is cool enoug
