Ukrainians watching this and taking notes…..
Ukraine has fire power its the Russian taking notes
Exactly what I was thinking.
FAB1500 is still better
Notes? No! We doing 😂
@@gruntovik good to hear! Slava Ukraini!
Sweet! Hope you're well, James. On my 5 inch, running 6s, I get 106mph with a GoPro strapped on. That's with freestyle props, not racing. You managed to go well over that. Maybe you should build one that will lift the Turbine and fuel!!😂
"on my 5 inch, running 6 seconds, with a go pro strapped on" you describing your bedroom antics?
@@sebpaine9095 6s refers to the number of cells connected in series. 6*4.2V makes for a 25.2V battery.
It was a joke.@@aleksjenner677
@@sebpaine9095 6s means 6 cell battery. Lot of 5-7 inch racing quads easily go over 100mph.
@@voltthrowerI think you missed the joke...
Cool!
I think you can combine the fins with the drones arms to reduce drag.
Also a 5 inch should hit around a 100mph to begin with, check your config.
Higher pitch props will be better for the top speed but drone props don’t come in very high pitches so you might need to check out some airplane props.
Looking forward to seeing where this goes 😃
He would probably have to move the arms down to near where the fins are located to keep the center of pressure behind the center of gravity
I'd say that "a 5 inch should hit around 100mph to begin with" is a bit of a stretch. A super-light racing drone, sure, but if it isn't optimized strictly for speed (minimal/fragile frame, not carrying a second camera, minimizing battery weight, etc.,) then 60mph is decent. My freestyle 5" quads go about 60-65 because they are very much not optimized for speed, in favor of survivability in crashes.
@@FPVenius yeah you’re probably right. I have a five inch freestyle with older components and the gps said around 100 mph back when it was working. But that might be with a tailwind and maybe the gps wasn’t that accurate. But I see 80-120mph being stated quite often. I figure that people with more experience can hit those speeds.
@@FPVenius a simple 4s nazgul with some watermelon props already gets 80mph for me. And whenever I get higher pitch its around 100mph. I think he's using low C batterys in this video
The take that space X got me cracking up 😂
It’s so nice to hear a young person who speaks well.
I watch so many of these project type channels I’ve gotten ridiculously good at seeing a pcbway sponsor coming from a mile away lol
GO BIGGER!!! Maybe something with multiple rocket engines and more powerful electric motors.
Edit:
Used the wrong wording. When you speak eight languages, getting everything is difficult sometimes. Thank you for the correction.
Moar boosters!
Get to Mars before Elon!
Electric motors, not engines
We choose to go to the moon 🌙 not because it is easy but because it is hard
MAKE IT BIGGEEERRRRRRRRRRRRR
This reminds me a lot of Thunderbird 1 from the 60's Thunderbirds show. An awesome build!
Excelent work!
Greetings from Ukraine 😉
Ukraine KNOWS drones😎
💀
🤢🤮
Love your vids bro
yeah me tooo!
Fr
Nicely done! If you want to improve the system, bury the rotor spars in the fins. That'll fair in both the fore and aft of the spars and sharply reduce the drag.
Love your work!
However, on this project I would go in an opposite direction, i.e "send" the drone initially with the rocket (possibly with folded drone arms), then, near the destination reachd, switch to drone motors for controlled loitering/landing...
Bingo
From a practical, aerodynamic and efficiency point of view, neither is particularly good idea. That's why militaries use very different types of drones and aircraft. Aerospace companies have been trying for decades to make hybrid VTOL vehicles, but it's difficult... they usually end up being sub-optimal in every area. Tilt rotor aeroplanes and helicopters with pusher props have some success. Jets like Harrier and a version of the F35 have VTOL capabilities, but are hugely expensive and complicated.
Lovechild between drone and rocket 😄
I’m sure combining stabilisers with motor arms could save weight and improve aerodynamics.
Go for it! Bigger faster greater thank you.
Nice James! Nice work and great video material!
I’ve got a video idea: What about adding a VR to an RC plane?
Defense contractors are taking notes on this video for sure
Or, they should be.
I'd definitely hope not, this would be a step backward....
Could you combine the fins and prop arms, putting the propellers further down towards the center of mass? I think that would be more stable at higher velocities.
Hey, avid fpv drone pilot here, just wanted to comment that I came with a nice gust of wind at a downward swoop from about 500 meters high with the dji fpv and managed 186 kmh, I'd recommend you do the same , take it high, swoop down with the wind, then engage the rocket, also try to use lighter parts anywhere you can
Edit: maybe heavier might actually not be too bad either....
If you do see this comment and try it with success, please give me a shout :P
Furthermore: maybe give it dual control surfaces so some servos to use control surfaces like an airplane, and maybe a rat trap mechanism of sorts that folds the arms with props down and out the way, then kind of glide it down... i dunno this last part is a very far stretch.
You are ready to impress the secret service bro!
You have the perfect tool and age for the job.
It's a UAV, unmanned aerial vehicle.
Would love to see more of this! :)
17:05 when you pushed full throttle it reminded me of something like a bassboat going onto plane and going perfectly flat
Very cool. It would be an interesting experiment to have drone legs be able to fold down out of the way for aerodynamics , maybe a very light spring holding them up. I’m curious to know if rocket would cause them to fold back out of the way during rocket stage or if drone motors are still able to produce force while rocket fires.
James have you considered building an rc oblique wing, it was a prototype nasa aircraft that had a rotating wing to optimise itself for subsonic flight with its wing at 90 degrees to the fuselage and supersonic flight with the wings rotated so that one side is swept forward and the other back. Somehow it didn’t fly in circles but unfortunately was never used to much effect as it ran out of funding otherwise it may well have changed the way we make planes forever as it has the pros of a swept wing but none of the cons of the complicated mechanism required to sweep the wings. Just an idea as you seem to be doing a lot of speed related projects at the moment. Love the channel 😃
Many flight controllers can control servos, if you have a spare channel on the tx/rx you can use a knob to control the pitch of the fpv camera using a single axis gimbal.
Some flight controllers also have support for controlling gimbals using the gyro so you could set whichever angle you want (and some allow for combining gyro with a channel input for modifying the target angle) and have it maintained while in flight, that way you could have the camera pointing horizontally, or slightly down, out of that bubble cockpit so you get a good view no matter the attitude of the vehicle.
Very cool project :)
Great project, but why not to land with the parachute? (definitely easier than with motors)
Soon as I put FPV goggles on and it felt backwards I'd tell my assistant "suddenly it's all backwards!, take them back off so I can try to save it!" Beyond that, some DJI gear would help with content/video quality.
For the landing, I would bring it close to the landing area through FPV, switch to stabilized mode (easy to assign the mode to a switch on your RC with Betaflight ) at a safe height, let it stabilize itself into a hover, remove the goggles and fly it line-of-sight through the landing.
Maybe you could try to use ducted fans (EDF) instead of propellers to reduce the drag? Some people have already built EDF drones, they fly ok but, as the power consumption is higher than the propeller drones, the flight time is reduced without offering any advantage. In your project, maybe you'll get higher speeds?
Wow, this is such an amazing build! I'm so impressed with your creativity and skill. Thank you for sharing your work with us!
I thought of something, similar to that with rocket motors and props back in the 70's even built a frame for them in the early 80's. It's funny but i had the idea for the drone back then lol. Nice work and results :)
I've always wanted to see a drone with a rocket motor aimed sideways. That is, the drone just hovers, and the rocket moves it forward.
maybe for your next vid you could make a rocket go as high as legally possible and maybe start a collab with other youtubers and get permission to go to space!
Quick tip for multi rotors - have a switch for Angle mode, it’ll auto-balance the drone and you can just bring it down safely
Unless of course you enjoy mini missile strikes on the countryside
I'd be tempted to build a larger single ducted fan OR quad ducts (4 tubes) inside the fuselage with 4 flap controlled vents on cardinal sides that give you thrust-vector control, and on the nose have air intake vents that can be closed off during rocket powered flight. The drag co-efficient improvement would be immense....... thus it becomes more of a control/engineering challenge.... but it's a hella interesting one if you can pull it off.
From an FPV Pilot: *oh, my god LOL* ahh, warms my heart seeing new pilots play the "wobbly" game in BetaFlight
It looks like your FPV camera has some sensitivity to UV light that gets translated into visible violet light in tbe feed, and that's extremely cool! I've often wondered what the world would look like if I could see UV.
I've been building a similar high speed drone, sans rockets, since I saw your last video and suggested it, and since the current wr broke his record I got inspired. I'm at 108 mph currently, still testing stuff and ramping up. I hope to make my 5 inch come close to 200mph.
Those white lines are from noise interference in your power, try isolating video lines as much as possible and maybe add a low ESR capacitor to the ESC end of your power cable
James. Firstly Congratulations, that was really good.
I was surprised that the motors didn't overrun and cause issues with the ESCs, I was expecting some sort of electric failure.
But if you go bigger with the drone and rocket could motor overrun be a problem? If its possible would folding props be a good idea?
Maybe there's a world record in it?
Keep up the interesting work. 😀👍
You should try working on the landing part of these aircrafts, because most of the damage done to them seems to be from the landing
I make motor mounts out of PLA all the time. Just slide a bit of cardboard (like a toilet paper roll) in between the motor and the PLA wall and it acts as a heat sink and insulator.
Dude you made a miracle again.
To me the most interesting thing was the huge increase in speed with the rocket body. I wonder if there are more efficient aerodynamic coverings that could be used for racing drones.
so, the reason it went faster is because you had the camera pointing directly upwards, and all four motors were pushing thrust directly behind the drone, this is commonly done when trying to make record fast drones, Id say if anything the rocket frame slowed it down a bit. But fair play to ye for getting the drone up and running in one week!! my first drone was like 3. lol.
What you need to do is build a high altitude rocket which launches almost vertically before leveling off and extending wings to glide far and back to the ground
sorry i meant jack brabham project it,s just that i was watching donald campbell in dumbleyung before hand sorry again , loved your dam busters plane seen that movie quite a bit and you done a good job . terry
im loving the ProjectAir golden age
Looks like your vtx output to the antenna might be touching the frame and giving you that extra static in the video signal. I can’t say for sure, but I’ve seen that issue before and that’s what the video feed looked like.
Couple things, you could use more powerful motors with higher pitch props. 5x5x3 would be a good choice for props. Also, since the rocket is stabilized by the flight controller, the fins should be deleted.
Awesome mate call it the drocket
Maybe you can try a fast drone on electric only, like the red bull one
This has so much potential in drone warfare.
I have been thinking about tiltwing drones with rockets for a long time. they made more sense to me. eventually, i decided a kinetic launcher makes a lot of sense over a rocket motor.
Very cool, I think hinged propellor fins would reduce drag a lot on a larger version.
Brilliant, looks very 1960s Sci Fi. Fireball XL5 anyone.
As you ignited the rocket motor, The craft seemed to pitch up a little bit. Was that intentional? If not, you could maybe add a counterweight to the camera to shift the center of mass back on a straight line with the thrust vector.
In laymans terms, you've just created the working model version of Thunderbird 1......awesome :D
Definitely go for bigger and faster! This ought to become a sport and record-smashing thing!
Red Bull have the fastest rocket shaped drone but I don't think they ever used rocket motors.
Things to achieve! 🚀
MORE, POWER, POWER, POWER.
Heck yea, go bigger and faster! That was a cool project!
Add a warhead to the front, that way it’s more cool and you can sell it to the wartime industrial complex. They have loads of money and could be a great sponsor maybe.
Bigger one. Experiment with the fins originating in the arms for the drone to see if you can reduce your drag load more by letting them draft off each other..... or it makes horrible turbulence and dies.
Mix X20 with SR71. SR71 with the four props of the drone. This might make the flight more controllable? Lift off like the drone and fly with plane control surfaces?
It's just a crazy idea.
Yes make larger and use turbo fans instead of props
You can also make the drone portion jettison just before or as the rocket engine ignited
Let’s go new vid I’m so excited
build something bigger and more powerful, mate! Good Job!
Nice, that has some proper Thunderbird 1 vibes! 😎
Great. I've been building one for the last couple of years, but in my head only LOL, and on the opposite side of the rocket/drone ratio if that makes sense. But this one's rocking, way to go, just don't stop any time soon!
I'm really curious how far you could push the flight controller to keep the drone stable if (for example) the rocket motor was really off-center, like angled at 15 degrees or something like that. I know this is completely impractical but it would be interesting to see what it would take to make the flight controller lose the ability to stabilize the drone.
That pulsing one reminds me of the interconnectable drones from Battle Los Angeles
Well done. Now time to scale up.
This is getting into Guided Missile territory lol.
6:05 probably due to a void or voids in the fuel grain. Have you considered building your own rocket motors?
yes build a bigger and faster one!💗
You have ALOT resistance when you light up the rocket. The arms have to fold inward into the body of the rocket to create the least amount of resistance to to the rockets aerodynamics. Once the arms are tucked in then you can use the fins to stabilize the flight, maybe. And you can not use the hobby grade stabilization to keep it in control. That's why falcon 9 has wing grids to control the decent. Falcon 9 has the wing grids folded back during launch. 😊
FUCK YEAH!! my dream aircraft did you take my suggestion? LOL
Have you considered the rocket acting on the horizontal axis of the drone somehow for less drag from the props over reviving.
“I don’t really know what this is…” radio controlled incendiary device 😂 perhaps?
Would you consider having retractable props?
Please build that bigger rocketdrone. I love your video's.
Greetings from the Netherlands
10:35 Take that SpaceX 💀💀

Thunderbirds are Go!!!
have you ever seen the Nemeth Parasol? You should definetely make one.
A push configuration with fold-in props might improve aerodynamics
Oooh, I've been looking forward to this since Maker's Central!
I would love to see a larger drone with three or four large rocket motors
This was the logical next step
When the rocket is used, motor will generate electricity back , could damage electronics and motors . Nice concept.
man, you're so cool! Keep going!
Faster! The current world record drone is about the same size and shape, but doesn’t have a rocket engine. It goes twice as fast!
Technical advice:
As your air speed approaches the maximum pitch speed of your propeller, the pid controller and motors will lose ability to stabilize or control the aircraft. Use high pitch, two blade props. Use higher kv motors, or higher voltage battery to keep the theoretical max pitch speed above expected air speed.
APC makes very good props for this purpose.
'test hop 1'
"Take that SpaceX"
Elon, "Your hired!"
😁😃
Cool concept! Maybe you want to check out the Redbull drone if you hsvent already! Looks dimilar to the design of this one.
if the drone fold its hands after the rocket ignition thisll be more faster.
ig the drone parts outside the rocket body making the surface area bigger and slows it down a bit.
BUILD THE BEAST! AND SEND IT!
Make one with fold back propellers or arms for more efficiency and faster speeds
Your blue coveralls are really sharp. What brand are they?
Try modifying it so that the arms of the drone fold in when you start the rocket motor. I believe that was you could get more speed out of the drone
Should ı use antenna tbs or elrs on my drones? Love from🇦🇹
Understood, ı'll note your preference for ELRS.🔥👍
How silly of a question this?
Need to work up a large AR fixed wing like a glider for extreme endurance that can be jettisoned after hitting the rocket motor.
