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
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
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.
Thank you very much!
... love your channel 👌
what a amazing project, and this being done by a father and son just adds to how awesome it's wish you best of luck on your future projects
The amp draw and ability of those batteries to discharge that fast is insane.
Sure is. Next version 200c batteries straight from the factory.
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.
Wow, thanks! 🤩 more good stuff to come
@@Mike-Bell what is that 3d software? great video !
@@kay834 I use Blender. Open source and free
@@Mike-Bell My mind is bent at just how skillful you are with Blender, that alone is award worthy.
@@sUASNews thanks 🤩
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.
Congrats to you and your son on breaking the record!
Thanks!! 😃
The left handed guy who uses a shorty pencil is the guy you should worry about.
😂
😂 😂
The fastest father/son duo on TH-cam! And in the world! Congrats! Love your work.
Thanks! 😃
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!
Thank you so much!! 😃
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 😄
Glad you enjoyed it! 😃
I had a very uncomforable laugh at 12 hp in a 10" frame.
The US Department of Defense is going to be giving this video a good number of views i think
Ukraine is here first 😏
That was my first thought, The military application is very obvious.
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.
@@ehjones Against stationary targets, yes. However, this high velocity drone could also be effective against helicopters and some planes.
@@2MeterLP no, because you forgot the payload.
congratulations To you and your Son
Thanks ☺️ always nice to get a comment from you
The shot in the dark with the LED on made it all so much cooler, that is quite beautiful.
Amazing video, Mike. So insightful!
Glad you think so!
Learning breakdowns from you is awesome, please keep making more!
We will!
i’m confused? just 24k views and 61.2k subscribers? for this level of production? truly underrated!!!
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.
Totally agree!!!
This aged like milk
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!
That is awesome!
We have improvements up our sleeve that should give another big speed improvement. You won’t be disappointed with Peregreen 3 😁
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 loved your previous video's but this is something else. Love it, you are amazing.
Glad you like them!
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.
That's more of an argument to CAD designers needing a background in graphic design than it is for Blender being the better tool.
This is an amazing video, thanks very much for creating it. Comgratulations to you both from KZN
Fantastic video, thanks for documenting your work!
Thank you for sharing your family project. Great video. I hope it inspires more father/son projects.
More to come!
As an FPV pilot for many years, this gave me chills. Inspired!
Wow. Amazing entineering and really well presented. Congratulations and thank you for sharing.
Thank you very much!
Great stuff, Mike. Excellent
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
Thank you! Will do!
This is so neat to see the wonderful engineering behind this. You guys are so cool. 😊
Thank you 🤗
absolutely amazing. loved the use of Blender, this has so much in it... look forward to seeing more!
Thanks a ton!
Awesome video! I particularly enjoy the animations. Well done Luke and Mike - dream team 💪
Thanks so much!
Amazing work Mike and good video. You need to do more works like this. Keep it up❤
Wonderful design, explanation and experience. So well deserved.
Thank you very much!
Now that's what's engineering is all about. 🎉❤
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.
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.
Beautiful explanation, thanks for taking the time.
Glad you enjoyed it!
You are the luckiest father alive. What a blessing to work together with the son.
And a son! Living their best live moments:)
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.
@@Mike-BellYeah, Blender works exclusively with meshes. STEP is for CAD.
What CAD program do you use in addition to Blender? Great work and dankie for sharing.@@pseudotasuki
@@cs9260 Autodesk Fusion.
Great film, and great teamwork and perseverance... Well done on the record!
Thank you very much!
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!
Awesome father and son collaboration 🇿🇦🇿🇦
absolutely incredible engineering
Incredible work, you guys pulled off something really impressive here! Im very excited to see your next iteration
Us too!
The fact that you bring the world along your journey of inspiration, design, iteration, testing, failure, etc., is such a gift to humanity.
I can see Ratheon taking notes... Brilliant execution, spooky possibilities on the budget 🫡
That’s so cool that you instilled this kind of work ethic and ingenuity into your son! My dad talk me how to drink and drive
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?
This is incredible Mike well done
Just scribed! Thank you, for sharing your knowledge! Well Done!
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.
Luke and I will follow your progress if you post the outcome online
Truly phenomenal! Bravo to you and your son, very inspiring video, beautiful work, and completely bonkers! Just WOW!!!
Thank you very much!
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?
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. 🤙🏻
This is fantastic. Please do more breakdowns of future Peregrine development processes!
Certainly will be making more …
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!
Masterclass! I’m your newest subscriber and bravo! Excellence of art, spirit and intuitive innovative engineering! 👍🏻✌🏻
Thanks. Welcome aboard
Awesome!
Amazing to see the use of Blender for design! Open Source FTW!
What OS you are using? Just curious...
Amazing video, this was a joy to watch!
So glad! and your comment is a joy to see 😊
Great video and many congratulations on this incredible achievement
Thank you so much 😀
Amazing achievement! Tks for sharing!
Thanks for watching!
wow, really amazing engineering.
This is amazing! It's great to know, that you have used Blender to 3d model this incredible creation 😆
This is just incredible on an engineering scale and on many other levels.
😮 that is amazing
What in the world? I somehow stumbled upon the coolest and best-presented TH-cam channel I have seen in years.
Well done!
Wow, thanks!
why did you not put the motorcontroller boards on each wing? seems like the perfect placement from behind the screen :D
Beautiful engineering 👍🏼
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
Besides your world record and your engineering skills … your storytelling is marvellous! Thank you for sharing your design process.
Wow thanks 😀
Good job! Very cool project!!
I asked you a question on Quora. Please read. Sorry, I sent a message. I did not find any of your other contacts.
Wow, this thing looks marvelous. Good job
Glad you like it!
Congratulations!
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 job guys!
Awesome work and i love the visuals
Im glad you enjoyed it ⏩
Congrats. Cool, great design. Could I ask, why have you used Blender for CAD modeling and not smth. specific?
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?
Absolutely amazing! Congratulations!
Glad you like it!
Incredible achievement!!!
such a humble choice of title! I mean you can never know if there isn't a faster drone on another planet
😂
That's the most technical use of blender I've ever seen! AMAZING!
Thanks 😁
Do you use Blender or something else?
Beautiful! Congratulations
Thank you so much 😀
Nothing better than a father and son venture 🎉
Great explanation. Love the iterative design approach.
Great to hear!
Nicely done, congratulations! :)
Thanks a lot!
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 !
nobody said this was a new idea
Proud of your team!
Amazing!
Thanks!
Love your work. So cool 😎
Thank you very much!
very, very cool!
how are you doing the control mixing? i.e. converting from torque commands to motor thrusts?
if by any chance you have a mixer that outputs something like 95% of max thrust + some small differential consisting of roll/pitch/yaw components -- there is something better! using a QP solver you can find the thrust commands giving max forward thrust while still satisfying torque inputs. for such small problems the solution can be found in fractions of a millisecond, even on tiny processors. If you haven't yet done so this might get you another couple kph! get in touch if you wanna know more, i have done something extremely similar at work :)
its simply the mixer in betaflight. there will always be a small loss of power as the pid controller with airmode enabled can only be active and stabilize the quad if it dials back from full throttle on at least one of the motors. this is why its most efficient to make the quad as aerodynamic as possible at the angle of attack its going to fly at and a good tune. since the drone doesnt fly completely straight forward but very slightly tilted up any drag on the body will push the body up and the pid controller will cut power to the bottom motors to compensate.
Thank you for such a well spoken and informative video. I am not the sharpest crayon in the pack but I was able to follow along well. Congratulations on your world record!
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.
That is so true. The power and capabilities of software and tools available today to anyone with drive and initiative is staggering.
Great video and great achievement! So what sec and battery did you end up using?
We did not list the battery and ESC’s because both were dissapointing.
We used the Dogcom 1500mah 160c batteries but they weren’t great, so Bonka next time.
And APD ESC’s but they also weren’t great. A lot of duds we had to put through their paces and they popped before we filtered out the duds and APD won’t acknowledge they don’t filter out the duds in their quality control.
Damm thats awesome!
Well done! Well done! Absolute mind blown!
Here before this blows up. What am amazing feat of engineering, so glad to be here!
Truly amazing video! Tanks for that!
Glad you liked it!
Guinness book record awarded!
Defense contractors must be absolutely extatic.
I look forward to the day you reach Mach 1. Keep up the great work!
Your video is so much better, nice explaination. Insane skills
Glad you think so!
I wonder what cool smooth videos you could get!
