5:24 small correction: you need 8 times the power for twice the speed. Force increases with speed², but power is force × speed
And restrictive exhaust nozzles would be a great idea too...
@@christopherleveck68355” drone motors actually, greater disk area and same efflux
plz be my teacher
Was just about to comment the same.
I though it went up by the square, i.e. double the speed requires 4 times that power. please enlighten me!
Someone may have already commented on this and it might be obvious to you, but a big reason the plane is so unstable during the motor burn is it's not pushing through the center-of-mass. It's strapped haphazardly to the top of the craft causing it to nose dive down as soon as it's ignited. Placing it centrally in the back or adding another motor underneath is a possible way to correct this. Always love your uploads though. Keep up the good work.
Job Well done! 👍 interesting and inspiring video!
I was on my way to comment the same thing!
also mounting the rocket motor further back on the plane will help.
Or, you could angle the rocket to point back and up, so that the thrust vector passes through the CG. It will also push the plane down, but if it's already moving through the air all you need to do is increase your angle of attack to get a little more lift. Or you could do what JATO's do, and hang the rocket underneath or to the sides, pointing it back and down but still through the CG.
I don't do avionics, only pyrotechnics and solid booster engineering, but yes it seemed to me that it would be much more stabilizing to put the booster under the wing level... Also he modified the balance and weight of that plane way to randomly 😂
@@baudouindesaintroman6337 Rockets are one of those things that mess up the whole "if it looks like it will fly, it probably will" heuristic. I think that's what we're seeing here, the complicated dynamics of rocket thrust and mass are hard to optimize around, so most people just slap a rocket on top of the plane since it feels correct. I blame 50's-70's pop sci artwork for this misconception.
Back in 1980, in a time before computer aided design, I build a SR-71 Estes-type rocket from scratch. I referenced photos from a magazine and used balsa wood & paper tubes for most of the materials. It was about the size of yours. Being a fairly heavy rocket, it had two D-size solid propellant motors, one in each engine. I was quite fascinated by the Blackbird at the time, but extremely inexperienced at building rockets. Needless to say, it flew, but not very straight!
I bet you used a slide ruler
@@ninkd0311 🤣 If I was only that smart... it might have flown straighter. 🤣
I made mine in about 1990. I even followed the guide to paint it with different black paints, some flat, some gloss, to simulate the different surfaces. It was maybe my 3rd rocket. I never actually flew it. I spent so much time on it that I was afraid to launch it. Years went by, got interested in girls, and it hung in my room for years. My mom probably threw it out at some point after I moved out. It was beautiful though. I spent so much time on it. After spending months staring at it at the hardware store. Wish I would have launched it.
@@gkoshinsky Sounds cool! I don't know what happened to mine either. I know I carried it home after the launch (more than I can say for some of my rockets! LOL)
Awsome
You succeeded in making the SR71 exceed mach 3.2 in scale. I call that a win! Mach 3.2 is 2400 ish mph and your plane did 2800 scale mph. Bravo!!
How do you scale speed and sizes?
By ratio of size
Say if you had a model 1/59 the scale you'd need about 1/59 the power for scale speeds
Edit: I'm not the greatest at math so I might be wrong but idrc
@@Rydog20 oh... That was simpler than I thought.
at altitude 71 did hit 3.3 thoo haha
@@Rydog20 what about air resistance? I know this sr is small but at 3.2 mach vs 200km/h its still different, i mean maybe my brain isnt thinking couse it 4:30 in the morning.. Correct me if im wrong pls.
you need to stop mounting the rocket engines to the top of the plane . they need to put in the back like the fans but in the middle . desing the same plane model but with the option to put in the rocket engines in the back like a fighter jet . and put 2 rocket engines in the back not one .
I agree with this cuz if it will be sitting on top, it kinda disturbs the aerodynamics
@@BragizTheFentanylAttractor not only that, it pushes the perfect in line thrust point from the normal engines way higher wich causes the plane to pitch down and generate even more drag .
Cool
You can can rocket motors that are essentially just multi stage boosters, you literally cellophane tape them together and when the flames hit the tape, it melts, drops off the dead Booster while igniting the second stage. More boost with less weight. Mounted underneath it with 2 boosters then the final motor with recovery chute.
That is true, but it is really hard to squish all of the electronic and also balance the cg with such modifications
Your video quality is taking massive leaps forward. This video was that of nearly an educational video on a mainstream media station. Keep it up!
The Insta360 rear facing shots are beautiful! Such a versatile camera. I'm just replacing my original one after a good few years of hard use!
Oh..and rocket projects are always a good watch 🤘
Totally agree! Thanks man
I love how you put your RC SR71 into your RC car and drove it to test!
What was he supposed to do with it?
😂😂😂
?? Im not following, are you saying that he could've jumped in the cockpit and flew it there instead?
It's not a project air build without rocket motors. Brilliant!!!
Next step - design and strap on a full flow staged combustion rocket engine on it
@@leomathguyyes😂
Goldbird
That video was the most (vicarious) fun I’ve had in a long time. Some excellent research and engineering skills on display. Look forward to the next project.
You can never go wrong with an SR-71
Love these flight videos a lot more than the boat ones
Ah James, this is your best one yet, brought a tear to my eye! Brilliant idea brilliantly executed!
Just a few minor thoughts:
Agree with everyone else who's suggesting a bungee-launch.
FYI these incredibly low Aspect ratio deltas are a bitch in roll, because the stubby wings provide damn-all roll damping. And at higher angle of attack, the vortices spiralling off the leading edges tend to bang into each other over the aircraft centreline, causing a roll oscillation. So if you can shoe-horn a rate gyro into the roll channel it'll make life so much easier.
I so just love this video!
That is one really cool plane. golden, rocket-powered, SR-71, 200kph, great footage and video so I'd call that a win.
I know nothing about RC planes but found this a thoroughly compelling snd informative video.
That little plane flew it's little heart out. It deserves a medal.
i swear to god when i watched his solar powered airplane vid i fell in love with this guy's channel and i got obsessed with this guy i am a science lover, and engineer lover even tho i am a early-teen love u project air
Props to the original manufacturer for making the landing gear accurate!
intentional pun? 🤔
mad props
11:52 Love the fact that Emma is working on the Elegoo OrangeStorm Giga in the background
Bro is gonna break the sound barrier one of these days
This toy would be my childhood dream, I can still get exited when I see him unboxing it.
always a good evening when project air drops a rocket plane video
Thanks for watching!
Great project. That was a spectacular flight. The way you led up to the rocket engine flight was just so impressive and all the work you did to pull it off. You had a well-deserved success. Keep up the great work.
The plane🔥
The neighbors reaction🗿
I’m so happy to see such lovely people here. Keep spreading the love!
A standard planform airplane designed for subsonic flight would be more easily controlled, easier to see the orientation and easier to launch. Perhaps you could try a small diameter folding prop with a motor brake to stop rotation of the prop when the rocket is ignited. Having the rocket pointing out of the tail cone should make it easier to keep the center of thrust aligned with the center of drag.
0:32 Bro that's hard core!! Wow, nice job!
James Bond: The Man with the Golden Plane
😂 such a good joke
I'm much older than you, but we did something similar when we were your age. To get the aircraft airborne, we set up a launch catapult using surgical tubing as the drive mechanism, much like a high start for gliders. It did several things for us, 1) it accelerated the aircraft over a longer distance so it would not disintegrate, 2) it stabilized the aircraft until it was well past the speed to be flight stable and 3) it aimed it in a very specific direction. I was on the controls and had my friend hit the trigger for the launch. It worked perfectly.
Who loves ProjectAir videos😊

Who doesn't
What was it befoore@@MsTatakai
That's why we watch
✋
😁
Use the drone to lift the aircraft high in the air. Install a cable release servo onboard the aircraft and with enough altitude, the aircraft may gain enough airspeed during the drop to start flying properly and you may discharge the rocket then...
Bro, your Mini is WICKED COOL!! So jealous!! and what a cool project! These speed record videos always have me on the edge of my seat!
4:00 that’s a gorgeous Mini Cooper!😮❤
Awesome build and definitely the right choice of plane. Congrats and sorry to see the devistation of the model. Keep at it!
Phenomenal channel man! Just stumbled onto it.
The attention to detail and the way you explained each step was great.
You need to build a proper High start. 10 meters of surgical rubber tube and a release. Lots of 3D printed options out there. your hand launches are pretty sketchy! Using a High start lets you keep both hands on the controller. I like your builds! Excited to see the next one!
I love how bro can just make surface to air missiles and not get in trouble
we all gangsta until a squirrel flys the plane and steals it
Your the funniest kid at school 😂
My kiddos love your videos. 🎉❤ super cool
I appreciate your efforts 😊
For making these videos
Great job ! I’m terrible at rc airplanes but love to watch them my father use to scratch build them really enjoyed watching your video keep up the great work !
I hope that you try your hand at it again later in life! It’s a wonderful way to connect with parents (whether they’re still with us or not)
@@vosechu I agree but no I always enjoyed RC Cars and trucks and were more my speed lol and have quite an collection of them that I really enjoy . 😁
1:59 is when the black bird breaks the sound barrier :)
No
Yes
The planes top speed potential was dramatically reduced by bolting on an un-aerodynamic camera and rocket. If these had been shrouded in there could easily have been a further 50kmh.
It probably would not get 50kmh more, probably only about 20kmh:
We needed to capture the flight from the air, so it was a compromise I had to make
@@Project-Air Nah it's okay. 100% increase in speed is amazing already. The camera shape might have made the rocket aerodynamics less significant by shielding it. Keep that aerodynamic optimization for a crazier project (2 stage rocket plane weight balancing when)
@@islam1337simoAgreed.
@@Project-Airyou could’ve modified the cockpit and installed the camera there easily.
This gripping drama was a heart wrenching saga and testament to the human spirit 😊❤🙏🏻
Removing the engine cone was a good idea because it's used to compress air, but if you wanted more power you should add a compressor stage (from the turbofan engines) and put a primary fan in the front to suck all of the air in, and by that, where you put the rocket engines you should put in the front a intake because air sticks into a body when moving, then connect it after the primary fan.
You could also have heaters inside of the engine so cold weather heats and you get more force. If you did that with only 1 engine vs 4 old ones you'll get even better power.
and where is he gonna get enough power for all that ? not to mention the weight lol
@@zmss8537 either mount a bigger battery (since the plane can carry it) and extend the fuselage and space administration inside of it (2nd is better) or add a generator to get some of the energy back.
@@Aaaaa1ggg there's no space, also the weight????
@@zmss8537 that's why you change the engine, if you have more air to push = more trust and efficiency. And the heater will propulse the air way more.
I love your videos! I am a Maldivian drone pilot and my drone pro E88 crashed recently. I really love RC vehicles
As I said in another video, you really need to change your radio to use ExpressLRS. The receivers are very small, even the ones with PWM outputs and the range and reliance are excelent.
I agree, I switched all my fpv drones to ELRS and fell in love. Even my Arrma rc truck has it now
Yep....ill never look back.
You get over 2 km range with standard orange relievers, why would you need more than that unless you are flying fpv illegally?
But then he could fit a gyro
@@TheRattleSnake3145 Kind of a silly comment.
ELRS wins over older control links like spectrum in basically everything, it's cheaper, receivers are smaller, it's range and link stability is insane and it's open source and always improving further.
People have gotten over 100km of range with 2.4 GHz ELRS, basically for a normal usecase you never have to think about range ever again with ELRS.
Additionally it comes with lots of additional features, adjustable data rates, model match, the ability to access settings on the flight controller flashing over WiFi.
You don't have to switch to a different control link if what you have is working fine for you but for controlling things that fly, especially fpv, having a long range, high performance control link that never failsaves is a very good idea.
Cool project!
Cant wait to the the next... Gigga... sized project you have coming!
Basically warp speed, you definitely take things serious, nice video and thanks for sharing.
plz get an ExpressLRS controller so you don't lose signal at long range again
Where did he loose signal ?
@@jas-FPV His Turbine video. What he needs to do is just add a proper receiver and a satellite or since he is running Spektrum he can just mount TBS Crossfire lite as it is plug and play with his Spektrum radio. That is what I use with my Spektrum radio and I can fly miles with my FPV planes.
@@jas-FPV in the "Foam RC jet" video
@@FarmerFpv or an elrs module bay transmitter....
@@FarmerFpv
I haven’t heard that. And he ises a TD Tandem receiver that uses 2.4 and 900 in parallel. So as long as he didn’t make errors installing it, this thing has the same range as crossfire or Elrs.
The minute you said building faster and faster rockets I subscribed :)
9:36 LUNCH BOX 💀💀💀
Fr 💀💀💀 new idea for 5 minutes crafts
The video and SR-71 were both so cool. But can we talk about how cool your vintage Mini is?? That car is just way too cool
He literally made budget afterburners

1:03 One of? na bro it is
Exactly
Mig-41?
Unfortunately for the Sr 71 the fastest (manned) plane ever was the x15 at mach 6.7
Fastest aircraft is NASA'S pancake thing. X-42 or smth idk
Ok so that was INSANE CANT belive you did that coolest EVERRRRRRRRRR!!!!!!!!!!!!!!!!!!
4:01 nice car
I about to comment that
@@TDC_gaming too late. sikkkke.

You are doing things we all dream of. Super cool stuff.
Is that legal 0:22
Who cares
I’ll make it legal
Yes (kind of)
Its on a private property so yh
No bro
i think you saw my last comment on your rc battle tank ship and made it 🤔🤔
I can only imagine how the birds react to your creations
Amazing video keep up the work!
You’re going to find that high speed aircraft have poor low speed performance. And “low speed” is going to get commensurately faster. You may need to look at non-hand launched options.
Please make a flying bullet😮😅
Hahaha 🎉
Not gonna lie, this was a kick ass video!!
You really should try to launch your next rocketplane from another airplane
Yes please
X-15
Lookup the M-21. This was a variant of the A-12 (the CIAs single seat precursor to the SR-71). This carried a drone D-21 which was a single engine drone that could fly higher and faster than it's mothership.
Chaps messing about with things is how the world moves forward. Keep up the good work.
Imagine if there was giveaways 💀
i wish
Thanks for including the freedom units for us :D
Great video, your method is sound. I look forward to your future projects!!
14:30 kudos to you for maintaining a decent flight profile, that's a crazy acceleration for the scale
Rocket powered RC Concorde would be cool.... Smash that sound barrier yo!
the way it disappears is amazing
Incredibly interesting video.! Thanks for making it.
I love that you used the SR-71 as it is the fastest plane ever made and flew in NEAR ORBIT.
Well done James yet another video I cannot stop watching until the end.
I like Emma, this channel needs more Emma!!!
Great video as always!!!
But it need more Emma!
Just amazing! Another airplane experiment I don't have to devise!
Legal parabéns para o vídeo muito satisfatório 👏🏻😊
HES BACK!
About 8 meters of 6 mm bungee cord stretched about 1-2 meters with a foot release will make your launches much easier (think carrier launch). The hook needs to be about 3-5 cm ahead of cg to keep ballooning minimal. If you can keep it upright, the fans will keep it flying after the plane comes off the bungee before it gets low and slow like your hand launches.
This is awesome. wathced the whole thing. feel like it would've been turned into a 5 pt build. first rocket powered test could've been a whole episode on its own.
That was sick keep up the good work my guy ❤❤❤
You absolute legend bro, great content here, put together really well, and some great engineering skills from you bro good effort
Nice video, initiative and experiment. You can try to use a VR drone camera to avoid lost orientation and help with controls. Use the canopy space to conceal the camera.
That was Absolutely amazing; I really want to pick up the E-Flite Blackbird in the future; soon as I quit bending the landing gear on my Cirrus 1.5🤣
Dude cool mini! I built and flew a model SR71 Estes rocket kit when I was a kid. I still have it and it hangs with my other model planes in my home office. Cool video sir.
Pretty athletic toss there
bro is going to be the next Einstein of RC😯😯😯
Put a rocket in each nacelle HEHEHEHE! Then challenge yourself to maneuver it using differential thrust. Nice work! Great video
That little rocket engine produces lots of thrust. That is almost as powerful as me when I eat Burritos and Tacos! I can probably levitate if I clench tight enough before releasing the blast. I love your rocketry videos.
That was VERY COOL !!!!!
Big salut 🫡 from France 🇫🇷
Hello!!! My name is Francisco. I'm from Brazil, but i like so so so the blackbird plane!!!❤🐦⬛🐦⬛🐦⬛
The first test flight where he said oh that’s so cool had me dying on the ground
You teach me what to do in rc
I saw the original rocket plane video when it first came out!
Absolutely fascinating!
That was awesome. I can't wait to see your next rocket plane video!
Thank you for another great video. I got a tip for line of sight flying, paint the plane with different colors over and under. Makes it easier to see which side of the plane is facing you.
Literally my favorite plane! Thanks project air!
I'm not into RC planes/cars at all, but this was a cool video!
