Answers to the most asked questions: Why is the toroidal propeller noisier, it should be quieter? - Read the description. Why does the 8 blade propeller sound quieter? - This is a very quiet prop in general. How do other props sound? - Less blades are mostly noisier. The drones weight is also a relevant factor (disc loading). Watch these videos of the same/similar drone but with different props as comparison: www.youtube.com/@quadmovr/search?query=movr5tpr1 What is the weight of the drone and the 3d printed props? - Read the description Where to buy this drone? Whats the name of the drone? - Its a custom build. Details written in the description. Is the video sped up? - No, theres no reason to do so. What you see is real time. Take a look at the cars in the background on the right. They are travelling at 80 - 100 kmh. Also watch my other videos for comparison: www.youtube.com/@quadmovr/videos Isnt this drone overpowered and therefore noisier? - No, this is a moderate powered drone. Heres an example of an over powered drone: kzread.info/dash/bejne/amt-rJmQm7XWfMY.html Is this flown LOS (line of sight) or FPV (first person view)? - Its flown LOS. Like classic RC airplanes.

I've tested a dozen or so toroidoal props sets on my various quads, both 3d printed or mold injected (most common way normal drone props are created). I've tried various pitches and lengths as I was a big believer trying new things and the Toro props really got my attention. I wanted quieter props that gave me longer flight times. Every Toro prop set I have tested are more noisy than standard 3 blade props. No matter where the throttle is set, Toro props pull more current and I always have ended up with less flight time per battery. They are no more or less responsive than standard tri-blade props, but they have more propwash and no amount of messing with my PIDS would clean up how the Toro props would shudder and shake when 'braking' or doing hard manuvers. I also needed significantly more throttle to get my drone to hover when using any Toroidal prop.

@@ABaumstumpf there are some things no amount of polish can fix: 1. the noise, the more the blade contact surface, the higher the friction. The higher the friction, the higher the noise. 2. the noise (yes, once again). Some of the parts are not facing the incoming airflow. Especially during turns. What will happen then? More drag, more friction, more noise. A lenticular propeller is thin and has a low drag on side movements. Not so for these propellers. 3. the drag, same with the noise. More surface and more angles, more drag. 4. the weight, self explanatory 5. the heat, more drag, more heat. Not that important on plastic models with low speed, but extremely important on large metal propellers at high speeds. 6. the structural strength. These propellers have a lot of weight on the outer ring. That weight gets increased a lot due to the centrifugal force. Depending on the materials used, adding friction and heat, the connected elements may break, bend or elongated. Big problems on the long run. Making them thicker may solve the problem, but adds weight and drag and makes them even more expensive. 7. the manufacturing complexity and the price. These things are far more complex that regular blades and they use more material(s), often high quality heat resistant one(s). This increases the costs. Without a big difference in efficiency, fuel consumption, speed or repair costs they won't become a viable alternative.

Assuming this motor is ideal for these props, the data says the multi blade are about 20% less efficient and have 20% less top end thrust. I fell the 5x4x6 are very locked in and much much more quiet. So if it is quietness that you`re looking for, the 6 or 8 blade props are the most viable option for that purpose at the moment. The multi blade props just need more distance to each other to avoid prop wash.

as written in the description these are just a very quick and simple design. a well designed and produced one may be very different. this simple design is less efficient, heavier, and overall worse. but i was surprised the printed props hold up the forces. the closed structure give them alot of stability.

Wow, I wasn't expecting those propellers to be able to put up with the forces involved with your flying. They are definitely not as fast. Did the battery last any longer with the toroidal props? Have you tried making the toroidal props with more of an oval shape instead of round and maybe more loops?

it's hard to evaluate the flight time with this style of flying. Also 3D printed props are 2.6g heavier. total of 10.4g. That alone affects flight time and flight characteristic. ok actually it's 6.5g difference between the 2 frames. So he could add 6.5g to make them equals and then hover tested them for flight time. MIT paper said that it's similar efficiency this mean it's less then regular props. The magic is suppose to be lower sound.

You are the master of los for real

What´s really cool on those is how you can see some of them slowing down in order to steer the quad, can´t usually see that with the naked eye in normal props.

Whenever I watch these high speed drone flights I always think of the the flight characteristics described in the tic-tac encounters. Stopping on a dime and changing direction. Pretty dope.

You always do amazing stuff - can't click on your videos fast enough when you release one. I had no idea a printed prop would hold up to that kind of inertia!

Very cool! AWESOME Flight and video edit!!!!

The toroidal blade system was impressive. Looks like a strong design. But what stole the show was the silence of the 8 blades... WOW! And it even seemed like the 8 blades speed was a little faster. Seemed to really dig into the air when performing your acrobatics... Really impressed. Thanks for sharing... Liked & Subscribed

A 8 blades toroidal design with a more polish construction surely bets the two... Both models have a VERY impressive efficiency transfer of power in a pure vertical ascension flight !!!

@deepsleep7822 It's worth bearing in mind that the toroidal propellers were 3d printed, whereas the 8 blade propellers seem to have been professionally manufactured. That would mean much greater precision, and that their size and shape had also been tailored for the drone in question. As such, it's no surprise that the toroidal propellers underperformed in this test. A more equal one would be comparing two two 3d printed designs.

Your dad is absolutely right. The toroidal propeller like this looks ineffective. The actual air speed changes among propeller radius., so the shape should be more complicated. We see only excellent flight skills. No efficiency measurement and comparison to the classic propeller shape.

I'm very impressed of your piloting skills!

I'm impressed by the great skills flying it! 👏

Surprisingly durable. I would have expected them to blow up at these RPMs, but seems like the second “support side” is helping quite a lot.

Dude sick YOU DID IT!!!! Well done! I hope this makes a million views. Your comparison with the 8 blade was super duper clutch TY

the way you're flying this drone is like a pixar animation. Some serious skills here! Maybe I just have an unskilled eye, but I thought the toroidal prop performed better, but I can't know if that was just the pilot flying differently. The conventional prop was definitely quieter though

Amazing drone flying skills!! The toroidal propeller drone flying was amazing, but quite loud. I thought it was fast until I see the 8-blade propeller demo, and it is equally fast and quieter too!. Not sure if you are able to compare efficiency, top speed, time to complete a circuit run, etc? Love this!

they are quieter, it sounds loud because you have no comparison audio... only the sound of the motors and blades... just the same as LED lights comparisons done at night... you cant go off of images for their output, you have to have a lumen meter for lights, and a A-weighted dB meter for audio

Thats the most crazy drone flying ive ever seen

impressive ! design and performances as well as piloting skills !🤩

Wow, Great video! I'd be interested to know the difference in relative flight times between the two propeller types. The toroids seem to handle the wind fairly well and be quite aggressive.

For something just printed out and screwed on, that looks quite good. Probably much room for optimisation on the model alone.

First of all that flying was absolutely exquisite! Second I kinda like the sound of the octobladed propellers better, the higher pitch is reminiscent of a supercharger.

Absolutely excellent demo !!! Hyper speed !!!

Incredible flying, I'm thoroughly impressed! I wonder how those props would perform without the print lines/smooth or when they have more blades

Awesome skill 🙌 Im really impressed by that performance. I knew about race drone stuff but that is quite mind-boggling. I think most of the noise comes from the ridges of the 3D printing. The transparent propellers are more quiet than i taught 👌
