Flying with four giant drone motors (ducted propeller paramotor) 

some people get naked to get fame, some people try to sing. love how peter just wants to fly and let us be a part of it.

I finally made it in to a Peter Sripol video!!!! I was the orange blob ahead of his first launch taking pictures. Peter, my favorite part that was not on video was seeing how excited you were to find the broken spars. That was great. Awesome machine you made, I wanna fly it next time. Let me know when were are flying in Nati. You rock brother!

A carbon fiber rod in the trash?!?!

Hi Peter. It's been almost 30 years ago, but I did a lot of work on ducted fans. In those days I didn't have electrics so I was using weedeater motors. 6 of them. Talk about loud. I removed the governors and was able to spin them to 10 grand. Between the noise and flying debris the neighbors forced me to stop and my test rig was just too big and complex to move around easily. I actually set it up in three different places but complaints killed the project. At any rate, my experience determined that a 5 bladed fan with straight paddle blades set up so that the fans were about 1/8 inch apart ( fans to middle engines front and rear ) produced the highest thrust. I was able to get almost 150 lbs with a 24 inch diameter fan. Yes, tip clearance was critical. I wound up using a three axis mount ( like a y ) as torsional flex in the mount would allow the blades to impact each other. The legs were airfoil shaped and pitched to shape the airflow in and out to minimize spiraling flow and torque effect. The intersection of the legs wiht the duct were about 4:1 width to the inner points at the nacelles. These intersections were CRITICAL. Any disruption of flow was seriously magnified downstream. They had to meet at a near perfect 90 degrees and radii at the intersections worked best around 3/32 in. I was experimenting with variable pitch blades to reduce spooling times when I quit doing research due to neighbors. This is where I really had problems with blade contact leading to some rather spectacular explosions and disintegrations. I had lots of vhs video tape of these experiments but a house fire destroyed them. I've often wished I could start back and have specifically thought that modern high output electrics were the key. Unfortunately I am now retired and disabled so I haven't got the funds or the stamina to persue this research any more. If you would like to pick my brain and check into my work let me know. I'd get a big kick out of working with a bright young person such as you.

Very nice! I wonder, is the thrust of coaxial motors the same as two separate motors?

I love you peter. Thanks for actually building these things most of us just talk about! I love that youre getting into paramotoring. Such an amazing sport.

Seeing this in person was pretty cool, such an odd thing to see flying around and the noise was insane.

“There is nothing more permanent than a temporary solution” (The ducts without any safety mesh) 🤣👏

BRO!! You have no idea how exciting it is for me to see you enter my world of squishy-wings and butt-fans! If you're ever in my neck of the sand, let me know! I have some EPIC places to fly!

Awesome work 😎👍

Awesome job! Those motors were huge. I have to imagine the sound and being so close to them gave people a jolt. Your duct design looked pretty good, but you could definitely squeeze out more efficiency. I like seeing how you push things to such extents. You really bring life to what others would consider grand ideas.

At This Moment Peter S. Realized: " RU-vid suks! I should just go into the business of selling Electric Paramotors!"

“Props” to you for the R and D on this. The easy comment would be just buy a moster but it’s guys like you that will invent a better bird. Nice job and nice BGD wing

The more Peter I watch, the more I think "with a few chinise electronics, I too could rule the sky" Half forgetting silly sky laws.

It makes me so uncomfortable that there is no screen or cage or anything preventing him from accidentally sticking a hand into the blades.

Here's an idea. As a paraglider pilot, I always dreamed of something to gain initial altitude before moving onto soaring flight. There's towing rigs and such. But what about a big quadcopter that is worn as a backpack, then jettisoned once you are up to altitude, and it flies itself back to its home/charging station. Not the worst idea, right?

One day, he may actually make a real flying car.

This guy is a national treasure.....We need more people like him🙌🙌

That "on" chime on the speed controller brought back some memories of my RC days

The drone shots of this thing in the air are just so cool to see. I wish to see more.

Nice, this gave me some ideas: 1. To get a "large pizza" while still using small motors, perhaps you could run them in series instead of in parallel, so to speak. You could either have multiple motors turning a separate single propeller shaft via gears or belts, or you could have the motors share a single shaft connected to the propeller. 2. To eliminate the torque roll from a single large propeller disc perhaps without the inefficiencies of typical counter-rotating propellers, you could have the stator and rotor of a single motor each connected to a propeller, so that there would be no net torque roll. Just some ideas I had while watching your cool video, Peter!

Such a fun contraption. Thanks for sharing it with us! I’ll be your test pilot again for the next version! 😜

On this historic day, we remember the Wright Brothers: Orville and Redenbacher, whose dreams and visions inspired generations. And now, again, one man's vision ushers in a new era of aerial travel, proving the power of imagination and intellect. The magic... of flight!

Classic Sripol video! Great balance between design, build and trying out, with his typical camera work, drone and music. Can't beat that!

You’re like the Myth Busters of Aerodynamics! I LOVE it! ❤️

Peter never ceases to amaze me. Well done 🔥

Dude. Big Balls. Crazy Balls!

I think you've got a hit Peter, this is the type of video that we love!

Another wild & wacky flying contraption, yay Peter!! You never disappoint!

looks like a lot of fun...you have a lot of creativity and ingenuity, its awesome to watch!

I'm constantly shocked by the innovation and skill this guy displays. Also, the ballsy-ness of trying out the designs himself. I wish I had even 1/2 this on tap! I don't even understand the math!

I will be buying one as soon as they are in production!!! Love what you’re doing. So inspiring.

Idea: add some protective mesh infront of the intakes so that you wont accidentally chop up your arm if you lean a bit too far to one side

Great stuff Peter. That looked like everyone had a blast.

Finally something cool in this year

Awesome invention, just stay safe. Don't get yourself either severely injured or killed. This is one of the most dangerous sports. Stay safe😀

Your inventions are always so spectacularly awesome! I've been waiting on a ducted electric fan paramotor for ever as it seems like a great use case for ducting. So awesome that you are the one to make it happen. Wonder if you could solve axial tilt with pid loop similar to drone controller.

Smooth out the inner duct surface area for better efficiency. Im guessing.

So frickin rad, man! Great job! - Have you ever considered using a large helium filled blimp, lifting body or a balloon, instead of the parafoil? Adding a 360° swivel-mount above the pilot and below the balloon would allow for some precise control over the aircraft. - That would be an awesome build to watch. 👍

It was cool being a part of this and seeing it happen. Come back anytime!

It's actually better if the back propellers have 20% more battery than the front propellers, because it makes it more likely for you to safely land when the batteries of the front propellers are completely empty. You won't get much more flight time, but just enough for an emergency landing to hopefully not end bad.

Why are you flying with so much brake? You are pretty close to stalling that wing!

Peter, so inspiring, again! Great job!

its cool to see peter taking two lucky big fans for a flight!

Очень классно! Я тоже мечтаю о такой мастерской!

Great video! Quick question what is the feasibility of a hybrid system and would that play well with the FAA limitation on Gas or is there now a gas AND battery limit?

Outstanding shipmate. Press on. USS Kitty Hawk CV-63. Jan 1980 to July 1983. Aviator for life.

Congratulations for 2 million Peter🎉

Hey Peter, my suggestion for reaching 2 million subs you should build a giant rc aircraft carrier , with working lauch catapults and arrestor wires and elevators .

Do I have safety concerns? Yes. Have I finished the video? No.

I love that after all these years you still use music from TechnoAXE, i found out about his stuff randomly forever ago and that ended up recommending your videos to me!

Well done sir. You are the kind of person (adventurer) that I hope my children grow up into.

You have the potential for differential thrust and, thus, flatter turns. Looks super good enough.

Aahh great build! Reminds us at the days when every flying thing was built inside a garage!

Nice. Fun to see all my paramotor friends flying in one of you vids

I love the new toy 😍 Can’t wait for the next adventure dude! See you soon!

ive wanted to make a double ducted paramotor forever one idea i had is if you mae it so the two prop ducts fold in like wings on a butterfly

I've said before and I'll say it again, this man is a national treasure. Oh, and a genius too!

Crazy video! Making a paramotor at home! Quality content Peter!

Awesome! Great work Peter!

Loved this. Good explanation, entertaining and humourous

Inspiring for sure. Can't wait to see how your designs evolve. If you can dream it...

You should add flexible solar panels to the ducts and you might extend your flight time some. We did this on my buddie's electric boat and it really helps. 8)

This is the most creative invention ever

Peter you absolute maniac. Keep being awesome.

Always enjoy your projects. Thanks.

This is so awesome

Congrats your this close to becoming the real life vulture from Spiderman homecoming!!

Dude, that is so freaking cool! Well done! 😎🤙🔥

A cool way to cruse the skies 👍🏻

The vulture suit is getting a nice start I see.

When strapping into your harness, you must always fasten your leg loops first, before your chest strap. Incase a gust makes you launch unexpectedly! People have lost their lives because of this. It’s more important hill launching, but needs to be done always. Safe flying

The real Gyro Gearloose!! Very nice!!

This is super cool. Top tier content.

Looking great! Awesomeness as always!

That was a lot of fun to watch!

Fantastic video! Absolutely love the new approach. For trike use, four ducts beg to be employed. Since I've got a couple of trikes (Fly Products and Flat Top) I need to get building!

Dude your hand and all your fingers. It had more power then I thought it would. Saftey my friend we love your stuff.

Awesome as always! Would be nice if you made a hovercraft with those motors!

I think you just made the Satisfactory Hover Pack! The satisfactory has 2 ducts which each have coaxial propellers.

it is always so cool to see this kind of stuff i really wish i could do this

You could do a up+down version of this. + Slimmer + Less heavy structure required + Lighter + Stronger - needs foam flow combiners - needs front covers - small decrease in airflow

awesome work peter!

You're a mad man you got me really anxious for a moment and you're so relaxed ^^

Peter, always enjoy your videos, letting us see the step by step learning curve to figuring the WRIGHT Stuff !

Nice engineering! The lack of a cage made me nervous though ;) but well done! Awesome video too. Keep going, I love your stuff

Interesting concept and would like to see it developed as far as it will go. Great work, thanks for sharing.

Crazy how quick you have evolved this

Yes, a follow up!

Awesomeness!!!!

You make some of the coolest things fly in non conventional ways. It blows my mind though how you mickey mouse some things together. Lol. "I got duct tape where's the trash bin?" It works though. Patiently waiting for more. Good luck!

As a Builder of small A/C ... you've got great skills and an even better Workshop!

Have fun, Don't Die I saw that sticker !!! she is awesome. (the foraging lady who always says that)

Great job.You always keep going until you get it right.

always something interesting and entertaining on your channel Peter.

Wow…what a build!

Perfect landing 👍🏾👍🏾

I swear, Peter is either gonna become a super *hero* or super *villain* with all the flying gadgets he's made.

Hell yeah! That was awesome!

Now you're getting close to my favorite hobby, Hovercrafts. If you're looking for a project idea, electric Hovercrafts are in super infancy and it would be awesome to see your take on it.
