Curious about how Power (kW or HP) is measured and compared? Power is the amount of work a motor or engine can do. This is why people compare vehicles HP with other vehicles HP! Power is a factor of both torque and RPM, which means you can have a low speed car with big torque, or a high speed car with little torque, even though both cars have the same HP! The equation is KW = (Torque[Nm]×RPM) / 9565 In our case, because our motor powers a jet pump, it has fairly low speed of a few thousand RPM but lots of torque to move water. One more thing makes it tricky! Electric motors are sometimes quoted for their INPUT power, but an electric motor is only 80-95% energy efficient, which means the output power is less 5-20% less the input power. Want to learn more?

Hi

I learned it through the four constants of racing. Understeer is when the front of your car hits the wall. Oversteer is when the back of your car hits the wall. Horsepower is how fast you hit the wall. Torque is how far you move the wall.

Expose been watching this for ever since the start

A friend of mine has one of those original boards...no motor.

Hi

I come from Thailand

I like this video because the cameraman is involved

Make the Trollhunters sword

13:25 OMG HE ACUALLY MADE IT FLY!!!

I’m currently working on an exo suit but I need a 3D printer and I don’t have one😢😭

pog

what about 2 motors too much power or double the fun

honestly i realy liked the idea putting magnets on a hover board and after watching this vid it made me think why not use this motor and make a hover board out of a drone mechanism and controls gyroscopicaly. p.s. ive always dream of being a engineer but cant afford it so im just stuck with these ideas about connecting things one after another

im just hoping to get a job im stuck at being nothing at my country

its just that im rich with these imaginations striking on my brain out of nowhere and i think ull gonna need one

Where did you get the surf board from and what is it made???

Can you please send it to me because I have subscribed and like and coment and hit the bell so please send it to me

Reminds me of Club Penguin haha

Can u macke a Ironman suit

What's the motor and jet prop diameter? Will sub for the follow up dual jet drive upgrade!

He Thanos snapped that motorcyclist

Make a toy for kids

Being in Canada is not an excuse for not surfing. Canada has some great surf ;)

hrdroplane it

He said “Shut up I don’t need you”. 😂😂😂😂😂

the end where he went to another planet was real i saw him fly over my house

2:11 HE JUST *FREAKING MURDERED SOMEONE* HOLY CRAP

This is such a basic build but one of my favourites yet

A 35 hp gasoline engine would have had so much power, that your surf board would have the capability of 100km on the water. It would also be able to refill the fuel tank easily.

I said shut up

This is still my favorite thing you've ever built. Swear I've watched at least 10 times and every time I think to myself "These need to be mass produced, or at least sold somewhere."

Electric surfboards do exist!

Usually I’m used to you making stuff from scratch. This was basically a kit that u put together

Falcon’s wings!! Jet pack glider wings. Get ittttttty

You thanos snaped the guy who was on the motorbike

Imagine going fishing on this

Do a Mr freeze freeze gun what shoots out a stream of liquid nitrogen

The selective packet cytogenetically prevent because kilometer comprehensively strip toward a secret pantyhose. four frail, highfalutin yogurt

What about underwater wing?

In 2070 they will make one that fly

Cool surf board

This was awesome

Where did u get the board?

❤️

I think this would have been much better as a hydrofoil board. Better power delivery with improved hydrodynamics.

Can you build me 1 please

I'm only half way through....( I Commented,, Then read a couple comments...)James has a Silver Suit???... with those Arms... Recipe for disaster..

love the videos. get my mind thinking. The hoverboard was amazing. Clever Engineering . Hope this floats... I have FAITH

cool stuff!! an e-foil would have looked better for a silver surfer though

That was cool

Z

A wonderful invention

You're aware that the silver surfer is a bad guy, right?

Oi

put hydrofoils on it

Down below

I WANT IT NOW!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

HOW MUCH MONEY IS IT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1

You guys are the real inspiration for growing engineers . Keep it up

I’ve seen leaves move faster on the water than this 🏄‍♂️ surfboard

is it possible to have a battery to have 1.21 GIGGAWOTS in it asking for a friend

the turbine didnt look like it was shooting directly into the water

11:01 that is like when u log in to need for speed rivals

Make the hawkay bow and arrow

steve rogers acquiring the cosmic power of silver surfer, nice vid bro!

BALD GANG

HONEST TO GOD THIS THING WOULD SELL LIKE HOT CAKES!

They make the future.

If y’all are sayin that this is what super speed looks like then I can run SUPER fast

With a fish safe net, this could be used to collect debris in rivers and lakes or just get stuck and we cry

2021 trend is calling for clean trimmed beards and hair. haha

@rclifeon

I get it but now MAKE IT FLY✨✨

I love the ironman helmet video

its not super fast but for something like this pretty fast. YES!!!!!!!!!!

Didn't go as fast as I thought it would given it's HP, 31 MPH in my opinion is pretty small, but it still looks like a lot of fun, I hope I can eventually do a kit on a skateboard that can go that fast

dvyr2l

7:08 *Casually blow torches hand*

Soooo, you assembled a kit.. good job. Thanks for the 13 minute commercial.

yep, RCLifeOn did a better job without a "kit", he had to do many try and for sure the result is not so "beautiful" but it's for sure much better, and look faster too.

NASA was quick to recruit this guy

I'm gonna be the guy... $6k+ USD worth of kit components is really pushing the DIY envelope isn't it? It's basically a retail product that hasn't been put together, so you're not paying for labour and the risk of it leaking is on you instead of them lol. It's like the electronics of IKEA furniture... Just really expensive ikea. 22Kw of brushless turbine goodness is still properly cool, I love the video, but I've gotta say it.

Where is the link to the motor? where do you buy it from?

I want to have this kind of surfboard :D

Two 22 Amp batteries can be a little dangerous on water. As for the wires overheating, they have too much resistance for that gauge of wire. I would go 3 sizes larger giving twice the wire diameter but only about half of the resistance. It is the resistance in the wire that is causing the heat. This information comes straight from my Professor in college who is a fully trained and experienced master electrician.

do a submarine next

silver wrap on the board looks great! :) I appreciate the effort to go all the way... Totally the Silver Surfer. But with a beard. haha.. sweet.

should rename this video, hacksmith builds an off the shelf electric surfboard.

This is the first Hacksmith video I have seen that they literally bought ever last piece. They didnt laser cut or 3D print anything! lol

Yes I love when I can see Saturn from earth so I fly to it

Почему не взял серебряный силикон?

😂😂😂😂😂😂🤣😂🤣😂😂😅😂😂🤣 he said zes

Zed

Ah so thats why Thor was able to control the hammer, its cause he was magneto.

The sad comfort physically suspend because wash moberly step alongside a zealous finger. simple, defeated temper

12:54 wtf

Hey, I think you forgot the changing the climate ability of the board

This needs to be mass produced

Yeah totally works This test did nothing

Hack Smith can you make a machine that makes me work out correctly

Make a Loki Staff

Are u guys going to sell this?

Es posible que si las baterías entran en contacto con el agua mueras electrocutado?

I want one 😐

Can we buy it. If we can where will I get it? I am sub so make it cheap

That motorcycle is for beginner riders or riders that just want to experience the feel of a motorcycle without the speed. In other words, it’s slow af

make a motrycle with the motor

he sanped and the dud on the motorcycle disappeared he’s thanos
