The very idea of 9000W motor/battery power in a product that small is just absurd. Amazing work!

So you decided to take on Red Bull and crush them, what a badass the both of you are!

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.

The amp draw and ability of those batteries to discharge that fast is insane.

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.

Congrats to you and your son on breaking the record!

The left handed guy who uses a shorty pencil is the guy you should worry about.

The fastest father/son duo on KZfaq! And in the world! Congrats! Love your work.

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 😄

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

Fantastic video, thanks for documenting your work!

I loved your previous video's but this is something else. Love it, you are amazing.

Thank you for sharing your family project. Great video. I hope it inspires more father/son projects.

Learning breakdowns from you is awesome, please keep making more!

congratulations To you and your Son

i’m confused? just 24k views and 61.2k subscribers? for this level of production? truly underrated!!!

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

Awesome video! I particularly enjoy the animations. Well done Luke and Mike - dream team 💪

absolutely amazing. loved the use of Blender, this has so much in it... look forward to seeing more!

Wow. Amazing entineering and really well presented. Congratulations and thank you for sharing.

This is so neat to see the wonderful engineering behind this. You guys are so cool. 😊

Amazing work Mike and good video. You need to do more works like this. Keep it up❤

Beautiful explanation, thanks for taking the time.

This is an amazing video, thanks very much for creating it. Comgratulations to you both from KZN

Wonderful design, explanation and experience. So well deserved.

Great stuff, Mike. Excellent

Great film, and great teamwork and perseverance... Well done on the record!

As an FPV pilot for many years, this gave me chills. Inspired!

Amazing video, Mike. So insightful!

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.

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 incredible Mike well done

no one tells you the drawbacks of being an engineer. i have zero interest in drones or drone technology and yet.... air squid go brrrrrrrrrr!

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

Truly phenomenal! Bravo to you and your son, very inspiring video, beautiful work, and completely bonkers! Just WOW!!!

Great video and many congratulations on this incredible achievement

Masterclass! I’m your newest subscriber and bravo! Excellence of art, spirit and intuitive innovative engineering! 👍🏻✌🏻

Awesome father and son collaboration 🇿🇦🇿🇦

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!

absolutely incredible engineering

Amazing video, this was a joy to watch!

The shot in the dark with the LED on made it all so much cooler, that is quite beautiful.

The fact that you bring the world along your journey of inspiration, design, iteration, testing, failure, etc., is such a gift to humanity.

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!

This is amazing! It's great to know, that you have used Blender to 3d model this incredible creation 😆

Amazing achievement! Tks for sharing!

Besides your world record and your engineering skills … your storytelling is marvellous! Thank you for sharing your design process.

This is fantastic. Please do more breakdowns of future Peregrine development processes!

This is just incredible on an engineering scale and on many other levels.

What in the world? I somehow stumbled upon the coolest and best-presented KZfaq channel I have seen in years. Well done!

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 work and i love the visuals

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?

wow, really amazing engineering.

Thank you for sharing this detailed and impressive video. It gives such a beautiful insight into the whole project & engineering that went into it.

Just scribed! Thank you, for sharing your knowledge! Well Done!

You are the luckiest father alive. What a blessing to work together with the son.

Nicely done, congratulations! :)

Awesome! Amazing to see the use of Blender for design! Open Source FTW! What OS you are using? Just curious...

Beautiful engineering 👍🏼

Congrats. Cool, great design. Could I ask, why have you used Blender for CAD modeling and not smth. specific?

Incredible work, you guys pulled off something really impressive here! Im very excited to see your next iteration

Beautiful! Congratulations

Great video and great achievement! So what sec and battery did you end up using?

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!

Good job! Very cool project!!

Great explanation. Love the iterative design approach.

Absolutely amazing! Congratulations!

Nothing better than a father and son venture 🎉

such a humble choice of title! I mean you can never know if there isn't a faster drone on another planet

😮 that is amazing

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!

I look forward to the day you reach Mach 1. Keep up the great work!

This video made remember you should never give up on your dreams! Epic engineering

great job guys!

Here before this blows up. What am amazing feat of engineering, so glad to be here!

Amazing job…keep it up

Your video is so much better, nice explaination. Insane skills

Congratulations!

I can see Ratheon taking notes... Brilliant execution, spooky possibilities on the budget 🫡

Incredible achievement!!!

Proud of your team!

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 :)

bro took away wings from redbull, without the millions of dollars redbull has you guys still did it

Truly amazing video! Tanks for that!

That's the most technical use of blender I've ever seen! AMAZING!

Guinness book record awarded! Defense contractors must be absolutely extatic.

I am agog at this accomplishment. What tools did you use to create the animations for the video, Blender as well? What video editor are you using?

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.

Very well done!

I wonder what cool smooth videos you could get!

Amazing!

Love your work. So cool 😎

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.

Impressive doesn't begin to describe this achievement.

Damm thats awesome!

why did you not put the motorcontroller boards on each wing? seems like the perfect placement from behind the screen :D

Great job! 👍
