I dare you to double it

In my opinion, Adding more thrusters in a straight line quickly hits the wall of diminishing returns. Instead, try mounting and stacking them in a cylinder and surrounding the collective ends in one large cone nozzle. This is how rockets are designed, with many burners in a ring inside of the larger cone that funnels the final air mixture in around them all. If you place them closer together in a ring and encapsulate them with a blast cone it should direct the collective force more efficiently.

looks like you're ready to take on the final boss. let me know when u want to come out and race

As an aerodynamicist I have one word for you - Streamlining! The mask, the, tank, the backpack - you'll break 20 mph for sure and that would be even more amazing. Great Show!

I swear Preston’s always in a good mood 😂 literally one of the most underrated KZfaqr!

I love everything about this, but your random songs especially make me smile ear to ear man 😅

the true kerbal approach to problem solving, add more engines until you get the results you desire

AMAZING CONTENT!!!🙏🏾😭loved everything the production is amazing, the comedic relief everything! This should seriously become a show

This dude is single-handedly keeping the water jetpack company in business.

preston may not be pregnant but he never fails to deliver

Seeing the aerial view looks like when David Hasselhoff saved SpongeBob

This video is next level awesome in every way from the videography and soon to be #1 iTunes hit about Jam Nutsto the overal humor and entertaining interactions. It was a great idea that paid off with a cool finish. Great stuff!

No joke: Preston never gives us up, never lets us down, never runs around or deserts us. Never makes us cry, never says goodbye, never tells a lie, or hurt us. Edit: But for real, Preston makes the best content on KZfaq for sure. I’ve never laughed this hard at something before. Seriously. Also the Mrbeast and Ryan Trahan songs are still stuck in my head lol.

FBI: We heard you made your own underwater jetpack, we need to talk about your known associates. .

Maybe a swimming cap and smaller goggles could lessen water resistance. Also placing some shrouds near the propeler intake to prevent seaweed or debris from cluttering it in every use. Hoping to see you break records with your cool ideas. More power :)

Preston is always in a good mood. I love that I’m new to this channel. I already love it. I found it out today like it is the best channel ever.❤❤❤❤

Saw this at the top of my side bar and immediately clicked off the other video I was watching. So many great choices here. Like the scene in the water where we couldn’t actually see you but it was still captivating due to the music choice. Also that final “Double It” in the song is so clutch! If it’s true that we get better with time, I can’t imagine the heights you sill reach. Bravo!!!

This was so fun to watch! The music amplified it too. You definitely have a way of getting people locked in on the idea and also on edge/anxiously hoping you succeed. The Shopify spot was like slick!

Also Sprach Zarathustra was a great addition to your super gear moment. Truly goosebump worthy.

Angle and 'wing' the support bars and then sand everything smooth and slick. I'm betting you could get 15 mph out of that setup. Excellent demonstration. Awesome vid. Liked your style. Thanks!

You should see if Robert can get you guys into an Olympic Sized Pool to really push the jetpack and maybe move the two outer motors to the middle on a raised section or pair them into 4 sets of triangles to try to reduce the jets from interfering with each other

Just found your channel last night by watch the 6 jet jet pack video and I loved it so it’s perfect timing that you came out with this one today

the cia watching this video:

Only 12? Double it and make a second row behind it

Watching Preston's videos before he has 1mil subs feels like being part of a secret club

Out of the hundreds of times that my brother's Strava account has been featured (for less than half a second) in a KZfaq video where an upgraded homemade jetpack is used to race a former pro swimmer, this is *probably* my favorite #putmoreengines Keep it up, Preston!

Awesome stuff! If you could 3D print a helmet / mask and body and oxy tank plates that are aerodynamic, which allows for less turbulence and drag to occur, I think you could drastically improve your speed and maneuverability on try number 3!

Only 12? Try double it again. I dare you.

Yes

Big fan. Double it next time

I haven't seen a video creator exude so much enthusiasm in years. 😂😂😂😂😂😂😂😂😂😂😂 Its literally shocking my depressed system lol

Dude...im not even gonna comment on what was or is right or wrong with what you built...i'm just here for the entertainment value...and you my friend NEVER fail to entertain!!!

Honestly glad I found your channel, your charisma is contagious!

A couple suggestions: 1.) You need a full face mask for air but one that is streamlined. You are probably losing about 20% of your thrust just to the drag from the mask and the bottle. 2.)Consider maybe a few slim air tanks inside a casing? The casing will alleviate some of the drag caused by the bottle in your mouth. I think with those two things you might be able to gain as much as 30% higher speeds. Have you tried them in depth? Try it at about 20Ft. No waves or interference from seaweed

Preston's videos are like the reality videos of Phineas and Ferb

Brother I just wanted to thank you so much I have been beyond depressed horrible time my life and I really needed some Jimmy up and make me laugh and your videos were savior for the first time in a long long time i laughed and smiled remember, last time I did I’m gonna keep binge washing. This is what I needed someone Brian sending my life to take me out of my depression in some way I have to give you the credit for saving my life don’t care about hanging out here but I was gonna be at the point where I was just gonna end it something got me on KZfaq and I saw your video somehow I don’t feel that way now. Thank you so much. Keep up the amazing your videos are something special, you definitely savd my life

This mans a underrated youtuber he should have at least 10 million subs. Keep up the good work!

Another amazing video preston, great content, love the positivity

Walking around the office singing "put more engines" is a great ice breaker.

The wake coming off your goggles is so sick - you nailed it!

this guy will always comes with a good content for his viewers

Fly to the Caribbean with this thing.

This is one of the funniest shows ever keep it up

This has golden era KZfaq vibes! Congrats my guy!

Loved the video! Im not an engineer (Though I'm in school for it). I think this thing would be easier to control if instead of spreading them out across a single wide plane across your back, you had them in a two- high stack. Itd help the center of thrust stay more consistent. A more precise thrust vector could also help with speed, and itd be less unweildy too. Maybe youll never touch this thing again, but in case you do, that might help!

Prestongoes should sneak into the Olympics with this!!

i like how he was afraid that he was gonna die out there and then became mad that he was gonna die out there bless this man

It would help to make yourself more hydrodynamic so you can flow through the water easily with less resistance. Make a cone or something to hold in front of yourself.

Bro I hope I get to the point in my life where I can make a full on jet pack

preston bro i love the fact you didn't give up like bro you just kept going after all that seeweed shit and failure

Congrats on 400K! 🎉🎉

Myes, simply impeccable content yet again. And unequivocally, do put more engines!

Preston is getting EVERY penny out of his auto tune purchase, and honestly, I'm here for it.

Your videos are HILARIOUS. Please Don’t stop innovating Prestongoes & everyone involved.

I feel like I just watched one of the greatest of human feats. Awesome video!

4:01 "Oceanside Beach" is a very creative name for an beach that is located at the sideline of the ocean. Wow! Much impressive!

DOUBLE IT AGAIN I DARE YOU! 👁👄👁 #PutMoreEngines

Oh hey my comment made it in the video. W

Dude this is freaking awesome... May have to build one myself

How have you not passed a mil yet? These videos are so well made

That's badass. I'm not sure I'd layout 6k+ to build it, but it's badass.

I would recommend larger props or even compressor fans if you want up power, also change to a small separate power source.

"The ballon dipper thing that kept happening" got me man 😂

Theoretically if you added more voltage to the motors you'd Definity go faster however you run into the problem of damaging the motors. Also it'd try to bundle them up as 2 cylinders mainly to focus on the jet streaming for better control.

Gonna be whistling "Put more engines!" while I work

Spacing them out is the best idea. Wingspan being wider means more water to push off from. Means more speed. Causing a bigger wake in the water. Creating a massive bubble to push off from. From behind you.also distributing the wait down to your feet as a stabilizer. Would help from the engines rising up to the back of your head. Needing a whole suit to keep in tightly in place.

Damn freaking badass! Just wait til goes commercial!!

hahahaaaa,that tumble was great -i wondered when it's going to happen!!!!

Instead of doubling it, Multiply it by Pi! Make an aerodynamic (or hydrodynamic?) circle frame around you that you can hold on to.

Too cool. Keep up the great work my man

LOL! "Chick-Fil-A open on Sunday kind of excited" !!!

Dude, really enjoyable videos

this is the first video i watch from this channel and my first impressions are: it feels so cool and also you look like Jonas Strand

This is awesome. It’s been a dream of mine to build something like this lol

The last thing we need is this man double the amount of engines and build an exoskeleton suit to carry it

Its performance issues are related to amount of water it moves, when its on your Back, intake is out of water, or not getting much flow, MAYBE underneath you, so they stay submerged & provide maximum thrust available, if you can ride it...

To prevent the ingestion of debris, you could cover the water intakes with some sort of mesh (like on those small jet engines used in rc planes and random youtube videos)

I think building this into a hydrofoil wing would increase stability and improve control.

Hand held and offset so they pull you along and you can move your arms to steer. Hold a grab handle with the throttles accessible to your fingers.

That looks SO fun omgg

I would've removed the plastic covering the button toggle, then you can run a bar that goes across the buttons so they all get pressed at the same time. It would be easier to control the buttons that way. If you knew an engineer, they could even make a board that has a bluetooth to a chip that you can place on the board and synch all the engines to one controller, there are many ways to go about doing it, but the fact you're not an engineer and still made a sturdy build is very impressive. Great work brother

This is seriously so cool

Hey!! You put some of the motors on your arms and limbs. That should help control a lot, but I see that without power, it decreases your mobility. I'm glad you also wore a full face mask, at least. And the fin!! Who knows how much it helped but...cool factor, right?😅 I'm glad that my silly brainstorm was enough to spur a few more experimental changes to the jetpack, what a cool video.

These videos entertain and scare me equally

I saw you at the shores that day! Didn’t know you were KZfaq famous lol. I was coming out of the water from a scuba dive

Damn that thing looks like fun. Very cool

Preston is my new favourite dude in KZfaq.. I love how he bought Autotune for RT outro and now is abusing the software in his videos. Love it

Best thing happened. I was recommended the first video. Then I see this gem in the playing next. What a great day

please make a part 2 to this

Get all the thrusters closer together, maybe in a triangular shape. Tie off all cables together and route them nicely. My best bet is over the shoulders and inline with your arms. You need a pony bottle, though I would strap it near your centre of gravity like in-between your legs or in a ventral position (on your stomach) Lastly you need fins. Not only on your feet but some other system. You could put your hands down tight to your body a slightly flap them to increase drag on that respective side

Great White shark: “That seal sure was crunchy …..”

@prestongoes add a wing type handle bar with all of the throttles on it and hold it out in front of you. It should help control and make it more streamline.

Streamline it closer to your body, they don't have to be flat on your back like that. You could set it up, so you can independently operate a left set and a right set to allow you to maneuver with just the jets alone. Id suggest a triangle shape stack. On your back; rough triangle spread out as flat on your back as you can without impeding your movement… A tight ⛛ on each side. Add a vertical stabilizer on the center jet on your back, approx. 3" tall. On your side center jet add horizontals at 1 inch or less. As for extending its distance. Figure out how to waterproof the charging port and a backup powerbank. 3D print a housing, perhaps.

Blud out here tryna swim faster than aquaman

You could try wrapping a metal mesh around the intakes to prevent some of the seaweed from accumulating

Try doing some reprogramming in some rewiring To allow the motors to use higher voltage Then what they would normally use

OMG !!!!... the songs are just perfect !.. why i took so long to discovery this ! huauhahuauha

I'm no expert in aerodynamics, resistive force is greater at underwater than air, hence like other comments said stremlined it, you'll achive the results guaranteed. keep up the fun! great video clip.

0:21 prestongoes: WEEEEEEE

i NEED the full "put more engines" song
