What a beautiful video - Incredible engineering, clear explanations, and a father son project. Doesn't get much better than that! Great work both of you, a well deserved record.
Think i found my new favorite channel. Having in depth technical description and great prodcution is rare nowadays, great to see the design process, would never have thought to test aerodynamics out of a window haha. Keep making videos this good, and analysis this engaging.
Been slightly obsessing about this cool thing so here's some calcs for interest's sake: If we look at the power consumption at 360km/h (100m/s) which is 5091We, assuming about 85% motor efficiency and 55% propeller efficiency we arrive at drag force of 23.8N. This can be reduced to a CdA figure of around 0.00396. Eyeballing the design section area of 150mm x 120mm gives us an A of 0.018m^2 yielding a drag coefficient (Cd) of about 0.22 or approximately that of a Tesla Model 3. This is kind of impressive except that it has no wheels, wheel arches or tyres which are one of the dominant forms of drag on a road vehicle so it suggests that there's at least some room and probably plenty for improvement. Also, at max speed of 510km/h we're starting to see compressibility effects being over Mach 0.4 in linear speed so there's no doubt that the propeller blades are well into the transonic flow regime so the 55% propeller efficiency above may be an overestimate. To make any appreciable gains in the record speed these problems will only be exacerbated. Time to get busy with area ruling and possibly ducted fans to improve the total aero efficiency. I also note there is appreciable voltage sag at the high speed run dropping down to 34V. This means that, for an assumed 12S system voltage of 44.4V nominal, there's about 2kW of power disappearing into the wiring as heat. (235A at 10V sag > 2kW). While motors are to some extent immune from increasing voltage from an efficiency perspective, the rest of the electrical system surely isn't, so bumping the voltage higher is only going to be a win, albeit with safety complications.
@@matthewbarnard461 Some of it is, for sure, but it depends on how and where the voltage is measured. Also it's still I²R losses which is just turning battery power into heat so increasing system voltage can only but reduce this inefficiency.
This is AMAZING! Congrats on the accomplishment… a good thing that you documented everything, which is a great thing to do in engineering. Great job once again!
From someone who can barely make a paper aeroplane, this is fascinating. Watching the design evolve to optimise the aerodynamics, airflow, and centre of gravity is amazing. It must have been so rewarding seeing it achieve such crazy speeds 😄
Small drones are practically undetectable and inescapable at much more conservative speeds anyway. Being cheap, easy, high range and having resilience to jamming would be more important than 500kph+ speed.
This has absolutely blown me away in terms of how effective your designing and surfacing was of v2 without doing aero computation. Eagerly awaiting v3!
I feel almost vindicated seeing someone else do their rapid drone prototyping in Blender, and especially your line that; "Success is achieving both excellence in performance, and esthetics" is something I've cought a lot of heat over from the pure CAD guys. Amazing work all-round!
This is a very interesting take! I feel like engineering/product design is to often teached to go from a sketched based 2D straight into hard and traditionel software such as solidworks/ siemens NX surfacing tool of what ever is used. Blender could be this perfect in the middel. It's abusrd to think about the hours i've seen friends, colleageas including myself put into interrating very complex surface models just modifying splines and addapting surfacecontinuity. The best thing is I have blender installed a couple of months ago exact for this reason but do not seem to find the time or motivaction tot get into it. I this video shows exactly why I should.
Thanks I value the concern 😊 and your comment. It more case of with youtube getting 3.7mill new videos uploaded each day that it really takes a lot to stand out above all that noise. But after a couple of years doing this I think this video is going to give me the catapult boost I have been waiting for. The subscribe rate on this video and type of story has gone nuts and is super high which is fantastic recognition for my efforts.
Awesome design, execution and performance, Mike Your Bambu printer may be able to print STEP files, which will behave like very fine mesh STL files, although that depends on the slicer. Great to see South Africans setting records. Netjies gedaan.
Dankie. Flippin lekker om SA bietjie te showcase. Blender doesnt work with STEP files unfortunately but it is perfect for the animation I make and it makes fantastic drone designs too.
Yup, Bambu Studio does support STEP. That's my go-to format when working with designs that have tight tolerances. Plus they're much easier for others to reverse-engineer.
10/10 Stunning achievement for both of you , and being able to keep it "in the family" and have FUN together as well as keep on learning , innovating and supporting is Mega Brilliant, Well Done
Well done guys, this is awesome to have local guys pushing the limits like this, very inspiring! Did you ever consider running CFD on the model, and do you think that would have helped the design direction?
Thanks Mike. Up till this point the level of technology is such that big gains have been possible through iterative exploration. But from here on the gains will become smaller and harder to achieve and require more sophisticated optimisations and we are running wind tunnel simulations for further speed improvements. And we have product manufacturers who are interested in supplying us with optimised components to go faster. If you have CFD skills I would be interested to know how you would approach this.
This reminds me of the passion I had when I was a child about aviation! Working together with your son on a project like this not only is super cool, but then to achieve what you did in the speed record is fantastic! The LEDs in the tail is brilliant! I am definitely looking forward to seeing what else you dream up, design, test, tweak, get to its best version as engineers and a father and son duo? Just lovely!
What an amazing project. I love the father and son team. I'm looking forward to use some of the things I learned from both of you in my next project. Congratulations
great to hear it. The need to distribute the PDB/motor controllers is something I've never seen on a hobbyist drone before. Also, you guys have the same heat gun as me, and good to see your solid Blender skills!
Mike and Luke, I'm sitting here in Joburg and so proud that you guys from my hometown have achieved this incredible milestone. Great videos from you both and have already shared the links with other drone enthusiasts. Also must add that I love the fact that you designed the drone with Blender. 👍👍👍. When I saw Blender I figured you'd move over to FreeCad but I was wrong.
Hi Jerome thanks for sharing the video. We are both ex Joburg. Blender has proven excellent for this project and is a must for animations. Blender is awesome. What is your filed/software used?
My university drone team may be attempting this record next fall. Been doing some research, and I want to commend your component selection! It's been really hard finding any configuration that performs higher in thrust simulations.
Awesome project! Looks like a fun one. Curious if you have done the math for what impact a carbon fiber exterior (or any alternative) could have on weight. The shell sure looks pretty light already.
The low hanging fruit development areas are still batteries and aerodynamics so thats the next version. And interestingly induced drag is near negligible at 500. You pay the price of weight in battery drain and manoeuvring. The angle of attack of 1 degree is all you need for body lift. It’s basically a wingless VTOL. I’ll be explaining this in the next video. So weight savings will increase speed because of a longer speed boost but not induced drag savings. Weight will get serious attention in version 4🤣 And when we get serious competition. 🤙🏻
I just built my first vertical frame and it flew away on me, it might be because my props are so close together as you were saying. Fascinating to hear more construction detail and the problems you had with your escs. also how you made your camera/nosecone and airshaper fascinating thanks a lot!
Thanks. I am a retired architect and have an Autocad Sketchup Revit Lumion background so Blender is a natural follow on. My primary need is animation so Blender is a must. Besides Blender is fantastic software. It can do pretty much all things 3d. What is your field/ software?
In general, the idea of such a device is not new,🤷♂️ it was already there, but you guys have brought the project to a really working fast state!👍 Thanks !
Maybe tow steered composites and custom aerostructurally optimized geometry of frame and motors for v4? In my experience, ADFLOW is a lot faster and more accurate than airshaper and it can do shape optimization
Incredible. The headaches and cost of prototyping and manufacturing on a cnc machine twenty years ago vs. the options of today has mind blowing potential.
Hey, I remember this guy called me on the phone a few years ago for consulting about blender. How you doing Mike? This is seriously cool. I grew up without a father because he was assassinated when I was 2, so I never had this kind of interaction, and even though I'm an amazing engineer I have simply never had access to the tools, space, or resources required to carry out this kind of experiment. To me, you guys are like ultra-rich. You are like infinitely richer than me. We are different classes of human. That's why I am a designer. Pencils are cheap. I have made countless models for other people to 3D print, but they will profit because I can only afford the tools to make the models, but they own the printers, and I will simply never have enough money to own my own printer.
Hey Tom. I cant say I remember talking to a Tom 🤔 do you go by another name? And for the record I also grew up without a father which is why I treasure my sons all the more.
@@Mike-Bell You called me on the phone after my blender tutorial went viral to inquire about Blender consultation, and I gave you a figure that I assume was too high, and you never contacted me again. I'm 100% sure it was you, I might still have your number. I know because I remember your name, voice, and videos. Do you realize what you have made? you've made the next weapon for the Russia Ukraine drone war and you gave the designs to the world for free.
Hey Tom oh yes I found your channel. I remember you. Are you still working for the architecture related company? Don’t let lack of tools define your potential. Your creativity is a powerful tool that many would be envious of.
@@Mike-Bell My father was assassinated when I was 2 and I was accused of Sexual Assault in Cape Town while running two popular comedy shows even though I'm completely innocent. It does not matter how intelligent or talented I am. I have been told since birth that I'm a genius capable of anything. My father was also a genius. It doesn't matter. I live under fascism. There is a boot on my face. I'm telling you, we are different classes of human. I will forever been seen as a crazy person despite the fact that I repeatedly prove myself to be in the top 0.01% for intelligence. I'm telling you I have no power, because I was born a criminal.
@@TommyLikeTom Hi Tom, I'm really sorry to hear about your difficult start in life. Your story is heart-wrenching. However, given your intelligence, you'll understand that dwelling on self-pity can trap you in a cycle that hinders progress and success. Stephen Fry articulates this sentiment beautifully. czcams.com/video/r_2kelqYz_o/video.htmlsi=dZcWIaX_HwLWtfQ_
Needs to take advantage of the Area Rule. (See differences in body shape between F-102 and F-106 jets). Spinners on the props will help reduce drag inducing turbulence, and could be landing gear. Potential to move those speed controllers in to the printed sections of the arms, to reduce cable mass.
Area rule to be investigated in next version. 500 kmh is already into some incompressibility territory so we suspect there are gains to be made with area rule. Interestingly the weight is only a burden to take off and manoeuvring. At high speed cruise the angle of attack is only about 1 to 2 degrees and induced drag from body lift is tiny. But yes wiring is heavy and around 8 to 10% of weight so needs optimising.
@@Mike-Bell I think there's mention in there of tip speed getting close to supersonic,... It'd require custom molds, and a gearbox on each motor, but having each motor drive a pair of contra-rotating props, with the trailing prop having a steeper pitch angle to further accelerate the air, might add a decent amount of thrust.
What a tremendous accomplishment, Mike and Luke! Congratulations to you both on this amazing feat! You’ve created a thing of beauty, and I can’t wait to see the next iteration. Although I am not a trained engineer, I was able to follow your clear descriptions and appreciate the problems and how you were solving them. Simply remarkable. I am so happy for you both!
Beautifully told story. I really enjoyed that. Coming from the country of my birth was a nice bonus. I couldn't help but admire the beautiful location zinging by in some of those shots. You must be so proud of your son. What a bright future he has. I feel like this is just the beginning of the drone age. All the best and thank you for sharing.
for streamlining the shape, there is an old blender addon available that will optimize aerodynamic forms. its not perfect, and uses assumptions rather than actual simulations, but its pretty good at getting a great shape.
Excellent video! The animations were awesome and that definitely covered everything I would have liked to pick your brain about. It's always nice to hear about others design philosophy. Also I just have to mention some funny coincidences. I'm currently getting my mechatronics degree too, nice job Luke! The other one is that I had originally named my speed record project the peregrine falcon back in 2019. What are the chances?
Are there any blender Addons you use to help model it? I have blender for a few years since 8th grade but I still find it extremely difficult to do things like this that involve precise measurements and parameters. Also, was all of the design done in blender? Or dis you also use other programs like cad or other things to help. Thank you! For instance, how did you model things like the camera tilt adjustment? Also, during the part of the video where you showed the short clip of modeling the NACA duct, how were you doing that? What was the greyed out shape you were manipulating? Was it just a boolean or was it something else that i don’t know about?
Yes all modelling and design was done in Blender. I dont use special add-ons. I find the overall dimensions of an object useful for sizing and scaling. And you can set up a special axis for non orthogonal modelling. And you can move and scale inputing numbers. The NACA duct was modelled with booleans.
Congratulations on building such a beautiful machine! Would be interesting to explore how durable your design/build is with the goal of characterizing operational lifespan and maintenance/repair costs. I'd expect optimizing these would present a entirely new set of engineering challenges. Of course, understandably, you and your son might instead prefer to focus efforts on just going faster.
9:15 "The software generates these elegantly sculpted streamline curves." I am sure you've discussed this elsewhere, I've yet to see your other videos, but what software did you use here?
Amazing engineering skills. You should collaborate with the team of Dronegods. Obviously the F1 drone cam its purpose was not top speed, it's goal was to be able to keep up with an F1 car for around 12Km's (2 laps) while providing stable high quality footage.
The very idea of 9000W motor/battery power in a product that small is just absurd. Amazing work!
Its absolutely insane. I built fast drones myself but never Had anything over 4500W
Better to fly fast to cool it!
So you decided to take on Red Bull and crush them, what a badass the both of you are!
It's a totally different system. This drone can not stay flying as long as red bulls drone.
@@grampafpvthe speed record has nothing to do with flight time
Redbulls drone was never about getting a top speed world record? 2 different drones for 2 different purposes
@TinyBearTim read the comment I replied to.. keep up bro..🙅♂️
@@grampafpv I think it can fly 7km at 350phh so it could in theory track the red bull car although the camera probably isn’t as good

The voltage drop of the battery is due to the internal resistance of the cells
@@matthewbarnard461 Some of it is, for sure, but it depends on how and where the voltage is measured. Also it's still I²R losses which is just turning battery power into heat so increasing system voltage can only but reduce this inefficiency.
I ran a sim and came to the conclusion its 28.67 newtons of drag at 140m/s, which gives it a Cd value of 0.172
The amp draw and ability of those batteries to discharge that fast is insane.
Sure is. Next version 200c batteries straight from the factory.
Congrats to you and your son on breaking the record!

That's more of an argument to CAD designers needing a background in graphic design than it is for Blender being the better tool.

@@Mike-Bell My father was assassinated when I was 2 and I was accused of Sexual Assault in Cape Town while running two popular comedy shows even though I'm completely innocent. It does not matter how intelligent or talented I am. I have been told since birth that I'm a genius capable of anything. My father was also a genius. It doesn't matter. I live under fascism. There is a boot on my face. I'm telling you, we are different classes of human. I will forever been seen as a crazy person despite the fact that I repeatedly prove myself to be in the top 0.01% for intelligence. I'm telling you I have no power, because I was born a criminal.
@@TommyLikeTom Hi Tom, I'm really sorry to hear about your difficult start in life. Your story is heart-wrenching. However, given your intelligence, you'll understand that dwelling on self-pity can trap you in a cycle that hinders progress and success. Stephen Fry articulates this sentiment beautifully. czcams.com/video/r_2kelqYz_o/video.htmlsi=dZcWIaX_HwLWtfQ_
Needs to take advantage of the Area Rule. (See differences in body shape between F-102 and F-106 jets). Spinners on the props will help reduce drag inducing turbulence, and could be landing gear. Potential to move those speed controllers in to the printed sections of the arms, to reduce cable mass.
Area rule to be investigated in next version. 500 kmh is already into some incompressibility territory so we suspect there are gains to be made with area rule. Interestingly the weight is only a burden to take off and manoeuvring. At high speed cruise the angle of attack is only about 1 to 2 degrees and induced drag from body lift is tiny.
But yes wiring is heavy and around 8 to 10% of weight so needs optimising.
@@Mike-Bell I think there's mention in there of tip speed getting close to supersonic,... It'd require custom molds, and a gearbox on each motor, but having each motor drive a pair of contra-rotating props, with the trailing prop having a steeper pitch angle to further accelerate the air, might add a decent amount of thrust.
What a tremendous accomplishment, Mike and Luke! Congratulations to you both on this amazing feat! You’ve created a thing of beauty, and I can’t wait to see the next iteration. Although I am not a trained engineer, I was able to follow your clear descriptions and appreciate the problems and how you were solving them. Simply remarkable. I am so happy for you both!
Thanks Maud. I always look forward and enjoy your comments and loyalty.
Wow, this thing looks marvelous. Good job
Glad you like it!
Amazing work Mike and good video. You need to do more works like this. Keep it up❤
Thank you for sharing this detailed and impressive video. It gives such a beautiful insight into the whole project & engineering that went into it.
Glad you enjoyed it!
Great video and many congratulations on this incredible achievement
Thank you so much 😀
Beautifully told story. I really enjoyed that. Coming from the country of my birth was a nice bonus. I couldn't help but admire the beautiful location zinging by in some of those shots. You must be so proud of your son. What a bright future he has. I feel like this is just the beginning of the drone age. All the best and thank you for sharing.
Glad you enjoyed it!
Amazing achievement! Tks for sharing!
Thanks for watching!
This video made remember you should never give up on your dreams! Epic engineering
Lockheed: Very nice, let's see Paul Allen's drone.
Fantastic video, thanks for documenting your work!
Love your content !
Glad to hear it! Always nice to know it is appreciated
That accent is from home the's no mistaking it
Incredible! Would like this video 100x if I could
Thanks! Looking forward to your speed attempt.
for streamlining the shape, there is an old blender addon available that will optimize aerodynamic forms. its not perfect, and uses assumptions rather than actual simulations, but its pretty good at getting a great shape.
Thanks for the tip. I'll check it out and include in the next video if useful.
absolutely incredible engineering
Here before this blows up. What am amazing feat of engineering, so glad to be here!
Bravo and thank u very much for tech details
Can we get a blender file for some payment?
Recently joined the SA fpv community, half-way through UCT mechatronics, I guess what's left is Guinness Record to match Luke hahaha. Amazing video💯😂
Excellent video! The animations were awesome and that definitely covered everything I would have liked to pick your brain about. It's always nice to hear about others design philosophy. Also I just have to mention some funny coincidences. I'm currently getting my mechatronics degree too, nice job Luke! The other one is that I had originally named my speed record project the peregrine falcon back in 2019. What are the chances?
Are there any blender Addons you use to help model it? I have blender for a few years since 8th grade but I still find it extremely difficult to do things like this that involve precise measurements and parameters. Also, was all of the design done in blender? Or dis you also use other programs like cad or other things to help. Thank you!
For instance, how did you model things like the camera tilt adjustment? Also, during the part of the video where you showed the short clip of modeling the NACA duct, how were you doing that? What was the greyed out shape you were manipulating? Was it just a boolean or was it something else that i don’t know about?
Yes all modelling and design was done in Blender. I dont use special add-ons. I find the overall dimensions of an object useful for sizing and scaling. And you can set up a special axis for non orthogonal modelling. And you can move and scale inputing numbers. The NACA duct was modelled with booleans.
Congratulations on building such a beautiful machine!
Would be interesting to explore how durable your design/build is with the goal of characterizing operational lifespan and maintenance/repair costs. I'd expect optimizing these would present a entirely new set of engineering challenges.
Of course, understandably, you and your son might instead prefer to focus efforts on just going faster.
Nothing better than a father and son venture 🎉
bro took away wings from redbull, without the millions of dollars redbull has you guys still did it
Amazing determination, skills and engineering. I'm so impressed! Congratulations from near the other pole :)
Glad you liked it! Where more specifically are you? Svalbard? Northern Canada?
This is incredible Mike well done
9:15 "The software generates these elegantly sculpted streamline curves." I am sure you've discussed this elsewhere, I've yet to see your other videos, but what software did you use here?
I use Blender. Great for this design project and amazing for animations. Enjoy the rest of my content.
Congratulations and well done.
Amazing engineering skills. You should collaborate with the team of Dronegods. Obviously the F1 drone cam its purpose was not top speed, it's goal was to be able to keep up with an F1 car for around 12Km's (2 laps) while providing stable high quality footage.
Thanks. We know the Dutch Drone Gods and have been chatting.
What an amazing achievement, Red bull must be in tears!
Just scribed! Thank you, for sharing your knowledge! Well Done!
