- Alright!
PLA toroidal propellers V2!!!
Potato props. :D
Here, I print out the V2 design from STRIKING FPV, and put the toroidal propellers to the ultimate test!
In this video, I'm flying a MIT toroidal propeller on a 3" Kopis FPV using ASTONISHING results!
If you're looking to up your FPV game then you need to check out this experiment! I'm using a MIT toroidal propeller designed by @STRIKINGFPV on a 3" Kopis FPV to see how it performs. What I'm discovering is ASTONISHING!

D gains back to normal, and throttle back to 100%.
Printed in silk PLA, these will take some abuse!
Lest see how she flies!

It's so cool to see them actually flying well! Job done, I can retire 🤣. But seriously, I never thought my design would end up being this stable.
I dare say, though, that silk PLA is playing a big role in making these viable as a printable prop, and that's a fantastic discovery on your part, I'll have to make a note of this for future versions 👍.
Don't go too mad with them, I took a other personal 'spirited' flight, crashed hard and did all 4 props. Again. 🤣🤣🤣
@@phatpigcustoms Ah well, main thing is no full throttle prop'splosion like your first run 😅.
I should also consider having the blade taper in thickness, like slightly thicker at the hub, thinner towards the tip maybe.
Glad to see these things fly after seeing the video of them being designed, I was left wanting so much more. Would be cool to see a noise/sound/volume comparison between typical 3 blade props and these. Isn't the main selling point of torroidal props the noise level?
@@NotOfThisWorld567 if only I had more time to do more testing. As soon asni am able to do these tests, I will upload something.
WTF SPOILER!! lol
i love how these tri-loop toroidal props look kinda like the old biohazard warning logo
I thought the same!
So excited to see all the versions that people are going to make and to see this V2 be a surprising success to a lot of what people imagined when a whole different prop design being used for drones so amazing because when a commercial prop comes out with one that’s injected molded it’s going to be crazy to see some head to head with top end props and just different applications this had to grow drones in all.
Mad isn't it! I'm just happy to try something different. 😀
Bad boy! 🔥 Easily the best version of these I've seen so far. Nice work, Johnny!
Thanks WillPowerFPV, I really appreciate your comment! Very kind. 😀
Sorry about the smelling pistake. Corrected. 🤣
@@phatpigcustoms haha, all good! I got ya.. 😅✌️
as a city centre apartment dweller - wow thats a massive back garden - lovely!
We are very lucky to be here. The kids, all 5 of them love the garden. 😀
Considering it is 3D printed, it's darn impressive!
Honestly, I am shocked too! 30,000rpm and somehow its still holding together. That's 500 revolutions per second!!! Potato!!!
They look very promising, I done a test print with ASA of the V2 3" ones last night and the design looks great and seems strong enough. Had a little bit of stringing on the underside so I need to retune my printer but looking forward to trying them. My plan is to print them, balance them, lightly acetone smooth them then re balance them and send it😉
I am too lazy to acetone prints - and usualy end up melting them. :D
Let me know how it goes - I am looking forward to the next prop evolution from STRIKINGFPV!
@@phatpigcustoms try a dip in some clear acrylic floor polish to smooth the surface a bit.
@@greggv8 what a great idea! 😀
@@phatpigcustoms I did a vase print of a dice cup in clear PLA then coated it with Future acrylic floor polish. Made it a lot more transparent. A second coat smoothed it more. If you have some of these props resin printed to be even smoother it's not difficult or too expensive to make silicone molds for pressure casting in resin. I've been doing silicone mold making and resin casting since 2000. I've come up with plenty of tricks to make the job much easier and results better. Happy to share my experience.
At least now I can say that “I was commenting on your videos before you were famous”… Cheers!
Hey Cliff! 😀
Love it!!! Oh --and the silk filament idea.. brilliant !!!! I have loads of silk filament to try it with! 💗💗)
Works for me! I'm sure PETG is better as would be ABS, but silk pla is easy to print and works fine for me!
DO the new design... the bi-blade one.
Possibly, but out of time for now.
They didn't have very much thrust when I tried them. Probably too much flex.
@@pirateradioFPV it's a tricky call, especially with all of these blades being designed without computer generated fluid dynamic simulations. I'm impressed they fly at all!
@@phatpigcustoms Yeah, I half expected mine to explode the moment I touched the throttle. I'll try the traditional tri-blades next 🤷♂️😂
Bi-loop*
NIIIICE 👌 So awesome to see this actually work 👍🏻
It's odd right, I expected them to fail massively.
"Its sunday morning and Im an idiot" This has to be the best start of a video ever
I only speak the truth. 😀
Beautiful printing! EDIT: I don't do any of this, but I do appreciate your guys work.
Thanks Matt, the print came out ok! quite surprised really. :D
Wow! These new props can really make a difference in the FPV world!
For cinewoop, certainly. I'm sure something will come out of these new designs.
@@phatpigcustoms waiting for it, and waiting for you to try it 😁
@@vexunaerials7185 count me in! 😀
Thank you so much for this. So many people trying to call BS on these props. I need a few sets like now. Lol.
Hi nearly, they were FUN to fly. And the grip is not to be sniffed at. It is mental! 😀
It’s F/Sunday and I was bored up until very recently..
Thankyou. 🍓
You are most welcome! Happy Sunday!
Very cool... this may be the fix for prop guards on whoops... you can get bigger props and stay under 250g
Now there's a thought!
Yep, the props have to be heavier though.. so may require a larger motor to have the same responseivness.. which might nullify any weight savings.
Interesting, you may get a bit more efficiency at a given size, but it's going to be giving something up too. namely this will be responsiveness, because these props are gonna weigh probably twice what a comparable conventional prop would weigh. That makes a big difference to the pids, and overall stability.
@@friendlyfire01 Absolutely. Nothing is free, and some gains will cost performance somewhere else.
I'm not saying these are amazing, but I am surprised they worked as well as they did.
Worth noting that the design is not the MIT one, but @STRIKINGFPV. It has the same basic principal, but thats about it in terms of similarity.
Quite a few people commenting on other videos that this is a scam etc. Well, from where I see it, these props are nothing to do with MIT, and everything tondo with STRIKINGFPV as it's his design based on MIT principal.
Anyhow, I digress... Did I mention they are made out of potato? 🤣
Excellent video mate. New sub from Philly.. were alike mate! Yahooooooooooo lol lol
Mikey
Nice one Mikey! Thanks for the sub. 😀 Yahooooooooooooooo! 😆
As a tech, I noted that this flight used about half the current to the previous flight video from a couple of days back. Had heard that these toroidal type props were more efficient and quieter. So far to me they do not seem quieter.
I would agree with you here. Just worse performance, no notable difference in noise, but a fun test none the less.
Bravo, thanks for testing.
My pleasure!
Now that’s pretty cool! Seem to fly just fine!
They fly ok for sure! Not quite up there with traditional props, but surprisingly good!
that DID look great 👍🏼 V2 way to go
V2 is surprisingly fun to fly!
Nice work! I printed a set of the bi and tri versions for a 5" in PETG last night and will try them out this afternoon. They are unique. I doubt I'll use them much but wanted to see if it was something I could print and try out.
One you ger to grips with the potential traction, they are a blast!
I'll be keeping a set handy for sure.
how did it go with the weight ? I was planning to print a set, but looking at Cura's expected filament usage/weight, it's like 3 times heavier than conventional props. So i kinda lost interest for a moment
I was trying to go to bed, but this must be seen. Love your work! 😴 waits!
Hello again Captain Gary. I'm glad you'll get to see Captain Monty Propellerhead the 1st in this video! 🤣
those props are beautiful and also sound really nice
They sound so different, it's quite nice really!
Nice video and great flying. Could you do a hover/throttle punch comparison video on your quad with these 'triloop' props vs. the regular triblades you normally fly? Would be interesting to hear the difference on the same recording setup. Maybe also compare the noise with a noise meter app on the phone? Cheers!
I'd love to, butnive just crashed the qwad on a flight pushing the limits. I'll print a new set and see if I have time over the next couple of days!
@@phatpigcustoms :D the classic. Sounds great, thank you in advance ;)
FYI quadmovr also just published a video on toroidal props, but it seems different ones. He has a comparison to 8 bladed as well and to me it doesn't really sound that much quieter ....yet: ruclips.net/video/UWoXFdRhPKc/видео.html
Nice and the zfold for fpv shit is epic
Thanks, and oh yeah - perfect for it!
good job on the props! enjoying your flying and commentary :)
Thanks very much alfa rme!
I like that the toroidal design is more conducive to 3d printing.
I absolutely agree with you here. I really don't think a traditional prop design 3d print would hold up well at all to 30,000rpm when made out of potato!
I'm from TamilNadu! I just saw your Video. Man 3D printing has enabled inventions from a research organisation to be printed at your home with decent knowledge 3d modelling. Imma Try this on my BETA Xknight. although very cautiously. Propeller Sound seems to be less from your FPV. Correct me if I'm wrong. Toroidal fins "For the Wins" Huge SHOUT OUT & Thanks to U ;-D MIT guys OGly
Love 3d printing, and combining it with fpv and experimental parts is just awesome!
I wonder what a injection moulded version would perform like.
Betterer I would have thunk!
Definately the best execution of toroidal props I’ve seen so far. Seen too many bad prints in tpu that do the physics zero justice. Switching to props-in configuration should prevent that yaw washout and make the turns much better.
Awe, thanks! I appreciate the comment!
Great setup and I like your flying! I'd really like to see the arms holding motors be able to change their pitch independently.
I wonder how that would be controlled and what you would gain from it... Sounds like an experiment!
Thanks for the comment. :)
@@phatpigcustoms I'm wondering would it help to not have to pitch the drone to move forward instead have the arms pitch while moving forward 🤔 Seems like it would have less drag 🤔 I'd love to see someone try it 😁
HA! This is my sunday morning as well! These props are mind-boggling. I just printed one of the bi-blades and the natural flex was the first thing I noticed, too!
Awesome! What material did you print them in?
@@phatpigcustoms I printed one bi-loop in transparent yellow PLA. Just regular old stuff knowing I’d print it again. I’m going to try it on an airplane today and see what happens!
I hope someone starts injection molding these soon. I bet the volume difference will be more apparent when they're molded in PC.
I bet. Strikingfpv will possibly be manufacturing these once the design is on-point.
As Striking said, everyone who will manufacture them, should pay license to MIT, because they have patent
@@SlavaChrome how is that possible? Toroidal propellers have existed on boats for decades, this isn't a new technology, it's just the first time it's been applied to drones.
Excellent props! They give outstanding handling, that's for sure!
the sound is really clear considering its 3d printed,
amazing , really interesting testing, thank you for being one of the first hehe
are they more like for cinematic drones? looks smooth and silent
Smoother for sure, quieter for sure. Fun - for sure!
I thought the buildplate in the thumbnail was a box of props you bought, im about to print some of these thangs!!! I might try carbon pla, its will likely break in a crash but should be ok for flying, i think.
Most carbon PLA is just carbon matt which does nothing for strength. Try PETG - nice and hot with no fan. Works beautifully!
@@phatpigcustoms i have some of that too, im gonna print alot of these thangs 🙃 wood pla for an old timey hand made prop vibe, low speed cruising. I have some glow in the dark stuff too but i dont know how strong it is
Print in warp free ASA or ABS, with tiny golf ball dimples and then acetone smooth them. For science
Edit: FormFutura makes some awesome ASA called ApolloX. Is also highly UV resistant.
Superb idea! If only I had the cad skills...
Nice progress! Could you make a sound comparison video with a sound meter :D
This does seem to be a much requested thing.
Sadly, I just exploded the props after a tremendous crash!
I'll print out another set and do this in the coming days!
This looks SO much like rural Northern New Jersey, you would be shocked!
Lovely!
This is the good old UK! :)
New Sub, based solely on your intro :D
Well, I am an idiot!
Thanks for the sub. :)
Im just entering the hobby and at around 12:33 the low battery was making me nervous lol. Im using a cheapo $60 dollar drone and modifying it. stripped the frame and droped the gear ratio so its straight from the motor and not using gear reduction. once I get the extra cash Im looking into the FPV drones looks like a lot of fun.
The copper stuffs beautiful.
Sure is. Looks great when printed slowly with lots of heat.
Super excited,.
Something new that does show signs of potential for sure!
Diggin' your channel, man. New to quads, diggin' that too. Have a fantastic Sunday!
Thanks Ian! It's all you guys with lovely comments like this that drive me to create more content. 😀
@@phatpigcustoms Looking forward to it. I like the way you get to the point but still give a lot of details. Relevant ones even, (which seems rare these days, lol). Watching your vid made me want to fly, but it's windy today where I am, and my wife and cats won't let me fly indoors, (Don't judge!), so it's an ebike day for me. I'm going to look into these props, though!
take all the 🙌drone enthusiasts🙌 and put them with the 👐battlebot communities👐
All of them? 😀
the other option to get good results imo is some petg. petg at a slowish speed with the cooling fans off, should give really good layer adhesion, and make it very unlikely to explode as its very impact resistant. silk pla has a lot of the same attributes, but id be worried about flying it in the summer as it gets soft very easily in warm environments.
Absolutely. Great results with PETG - the choice for 3d printed props for sure!
Another great review 👊🏻
Thanks Triton FPV! I really appreciate your comment!
Love to try these on the DJI FPV, . just need a 3d printer.... :D
3D printers are a pain in the ass. Absolutely get one, they will ruin your life and complicate everything. A must do indeed!
Liked and subscribed!
Thanks Ashley, your sub means a lot! Johnny.
5:15 LOL how to get a cat out of a tree
He usually has a sniff everytime it gets set down - not today though!
Really interesting... i enjoyed this video
Thankyou! :)
The sound of the blades have a very distinct whine-kind of reminded me of what happened when CFM International switched to a larger front fan on the LEAP jet engine and “buzzing” noise of the fan blades was replaced by a very distinct whine.
Yessss! The noise is more rounded and almost more refined / tonal. Very odd hearing a different noise!
Great video thank u
Thanks for watching and the comment H2O!
This 6 blade loop prop needs to be compared to standard 6 blade props comparing them to 3 blade props is just stacking the deck.😎
These could be used more for whoops in small spaces with more safety.
Someone will make a lot of money selling these for that purpose. Pros will buy this.
It will still slice a finger if you poke the top off them!
@@phatpigcustoms even with ducts thats unfortunately possible also.
Where this would shine is in small places where ducts would be too in the way.
Its Sunday morning, I'm an idiot. Can't even count how many times I've said that phrase
Nice video... BTW if you end up in powerline, mono filament fishing line isn't conductive with a 3d printed plastic casting practice weight, but you didn't hear that from me... 😉
Nothing to read here. Move along... 🤣
Does everyone want to come to your house and fly? I do. But let’s put that aside. I enjoyed your video. Thank you.
Yeah right, no one will fly here as I'm digital. 🤣🤣🤣
Love your PID tuning guide by the way. Top work!
@@phatpigcustoms Thanks! I put a lot of time into that concept! 😵💫😂🤣😂
@@phatpigcustoms Oh… and we could take turns flying. It’s easy if you think it out. 🫡
Your cat is very sweet!
I love you. XxX
Quite astonishing m8
home printed potato props at 30,000+ rpm? I agree! :D
looks great!
Thank you! It was great for what it is!
I’m jealous of his drone piloting. Even though I have a drone FAA certification, I still consider myself a novice flying.
Have you seen the new CFM RiSE ductless high-bypass jet engines? What interest me is the new fins behind the propeller rather than counter-rotating blades or the traditional duct. I think they are designed to cancel the helical flow from the propeller output so it doesn't spread rapidly and lose energy. The duct on traditional high-bypass jet engines serves a similar purpose but weighs so much more and the older ductless turbofan designs wiith counter-rotating blades have a stupidly complex gearbox. This new design has an adjustable attack angle on the fins, I think, which they could adjust with RPMs or just to tune for performance but I figure you could do a fixed set optimized for hover and it might be worth the effort even if it's fairly specific to the vehicle. Adjustable ones might be worthwhile for large camera drones.
Yeah, interesting to see these spring back up after years of dormant development status. They were so nearly ready for release 40 years ago!
There is an expired U.S. Patent 6,736,600 "Rotor with Split Blade" to Rudolf Bannasch that looks similar to the MIT toroidal propeller. Please see Figure 7 of U.S. Patent 6,736,600. I have no idea of Mr. Bannasch's propeller has good performance or not, but it would be very interesting to see a comparison between MIT's propeller and Mr. Bannasch's propeller, especially since U.S. Patent 6,736,600 expired in 2020!
VERY interesting!!!
Imagine using another two step layers finer like honeycomb. Two stages smaller wings are quieter than two times
Great video, looks very promising! Thanks for taking the time to make this video. Do you think that this type of propeller with replace the current commercially available propeller in the future?
Probably not anytime soon as the efficiency is not there - yet.
As always, time will tell and the design may well radically change!
@@phatpigcustoms Just subbed your Chanel 🇨🇦
@@RC-Flight thankyou! I appreciate it!
Extra grip compared to 3blade prop you say?
I had a feeling that would be the case, after all; it's practically a 6bladed prop for the most part...
Thanks for sharing!
Absolutely. Superb grip, I was pushing much harder through the turns with way less throttle than normal!
try doing little dunks in the trampoline net, new trickshot unlocked!!!!
If only I was that talented!
so now we just need to print our own props😁
A printed prop will never be as good as an injection moulded prop. At least, for the next 10 years till 3d printing matures even more if at all possible.
Yo I subscribed good channel man.
Thanks so much! I really appreciate your sub! Johnny. 😊
WAAAY BETTER, NICEEE
WAAAAAAAAAAAY better! Yes!

Would love to see a design that's been made in CAD using CFD analysis, 3D printed on a resin printer
I'm utterly useless at cad. Microsoft 3d builder is about all I can deal with. 🤣
I would like to see you use owl feather technique and sharkskin or golf ball dimples to improve the slipstream quietness

@@ghafoorhussain6677 teehee. :D
Доброго дня. Я думаю надо подключить к динамометру и проверить тягу на обычных пропеллерах и на новых пропеллерах. А то возникает ощущение, что единственный их плюс это то, что они крепче. Ну вероятно крепче они из за того, что в них в шесть раз больше пластика.
Someone has already done proper thrust tests with good results!
Want a really crazy project? Ditch the toroidal prop and make moebius bottle prop. A moebius bottle NOT a Klein bottle. Klein have no aerodynamic properties that a brick doesn't also possess. The prop must be uniform throughout the entire strip. The props must also be set up in a quadcopter design such as you are currently flying. The prop should be mounted on the centre axis of the moebius bottle.
Love the improvements your toriodals have made. Are you going to try to improve it to the point where you can use your drone to cut the grass next summer? As fast as that thing goes, you could probably have the whole garden cut and trimmed in just a few minutes.
I'm looking forward to you getting it under such good control that you can fly at high speed underneath the caravan and back out on the other side.
I'll take a look in to that!
Basic rule of spinny things: weight = bad
Same with a hula hoop!
Ground effect should be more prominent. Toroidal propellers are capped so should be forcing air down more than open blades that have less compression beneath them
Well done.
Thanks DroneDude64! I appreciate your kind comment!
Don't mind me...I am here for the cat 😍
Cptn Monts says "meow".
@@phatpigcustoms Flaffy and the rest of the gang says: Meow Meow ack at you habibi.( They all are rescues from the streets of Qatar). I would like to see a noise test and battery endurance. Hopefully soon this design of propellers will be available for the DJI line ,to calm down that angry wasp noise of their drones
@@KonstantinGabriel1978 awesome! Meow.
Check out the latest v3 video. There is some noise comparison in that one. 😀
I’m a 3D pilot and I’m very curious at the benefits of these for 3D. They are symmetrical so they are a perfect solution
Now there is something I would like to see!
I haven't tried 3D yet, and I am certain I would crash - but what fun it could be!
You can take a look at the flight of a LOS pilot with such type of propellers here:

@@muggzzzzz quadmovr is a monster lol
@@phatpigcustoms nothing between you and it but air an opportunity. I can help you with setup. Best way to learn is just flip over and fly straight lines which allows your mind to get used to it. Turns are cross coordinated and instead of pitching back to keep the nose up (upright flight) in turns you pitch forward to keep the nose up(inverted flight) another thing you can do is take a tiny whoop in your hands and physically do the actions so your eyes see it and translate it to the flight.
@@the_darkside_fpv I wonder if liftoff or velocidrone has a 3d option!
Failing that, I'll order some 3" props and run them on the 4s Kopis with those 3800kv 1507 motors. Could be really fun!
Terrorial props work even better when they are Stacked and rotating in opposite directions on an X8
Oooh. Dont tempt me. 🤣
"You are in a no fly zone"...😁
Nope!
Hi henry srry i spelt name wrong itsmr r ware robert just contacmeand iwill xpla e thanks robert
I want to see a 3d version!!! I bet it would be amazing!
My crashes would be even more spectacular and instant! 🤣
I would love to see you use
Flying around is cool, but how do you know which propellers are more efficient? Maybe try simplest tests like this: measure hovering time, measure loudness. Regular propellers vs toroidal propellers.
Regular are way more efficient. The amp draw reflects this pretty accurately on hover. Almost twice as bad on consumption.
Yeah, I tried the bi-blades on the 4", that didn't really work. Almost no thrust, felt like it was mostly in the air due to the ground effect and when it was able to push itself out of the ground effect, the voltage instantly sagged really hard. Probably too much flex on the PLA, even if I tried to enforce them with the CA from the trailing edge. The yaw sinking definitely was there with those, too. Tri-blades is clearly where these are at, should they ever gain any kind of popularity.
That's my one reservation with bi-loop design. Tri-loop all the way!
teehee
does anyone seen how FLAT the toroidal boat propeller is vs how everyone keeps making these open at the sides like if they were ducted?
Not a clue. But I'll look at some more pictures!
Some dude thin coated some in nail polish to fill n level the surface better than print.
Great idea!
everybody talks about that but missed delson aeronautics low noise propellers
I've used some in the past on model aircraft. Can't remember a thing about them!
@@phatpigcustoms apparently they sold a patent for new ones to a US based manufacturer : ruclips.net/video/1LNKL92kMKE/видео.html
Can you do a 'sausage' test comparison to see how much safer these might be for our fingers?
Cumberland, Toulouse or Chipolata?
@@phatpigcustoms :D Your choice. You can even use your fingers for a more scientific approach if you prefer... 😉
.
@@paulhope3401 already did that last week. Just pulled the stitches out myself today. They were itchy. 😂
Video starts at 5:30
Flying starts at 5:30 😉
Try variable potch though pn each toroid,will improve performance quite a bit and further reduce noise. Pitch should start very low and get steeper from there
I'll wait for the next design and test - then see how it does.
I'm no engineer or designer, just an idiot with a camera. 😀
@Will It Mod? i love how smart people just love to call themselves idiots, and idiots love to call yh4mselves smart haha. You are doing great and I adore this natural curiosity to science in people. Since you can do cad, its easy, changin pitch is really a one minute adjustment to your sketch curvature. And will ge very interesting to see what it does. The idea is that air should enter the fan surface at much softer angle to avoid turbulence, and then gradually you increase pitch to turn air direction into downwards. This is how mollusks build their shells btw and its a very optimal way actually. There is also a coeficient there to try, but i forgot what it was.
I want to order a set of these blades made in PEEK or Ultem, the machines that work in those plastics are like 70k, but you can get parts made through xeomety for a decent price per/cm3.
using a high end plastics in a solid high resolution SLA printing would be ideal.
Did you notice it being any quieter? Still sounded pretty loud from the video
