If it doesn't look like it should fly, and it flies, I auromatically like it

Helicopter? Right! More like rocket powered rotating knife I love it !

That was really cool, if I just saw a picture of that I never would have thought it could fly. I want some of those motors now too!

When I was a kid (about 65 years go) I bought a Jetex-powered helicopter. Jetex was a small solid fuel rocket motor, about 1 inch long. The helicopter had two rocket engines at the ends of the rotor, like your first design. I too encountered the problem of sometimes only one engine firing, which shook the copter violently. When it worked properly it flew quite well.

"No control whatsoever"... sounds like a plan. You and @Integza are definitely spending too much time together🤣

2:52 There is something really satisfying about seeing it start to rotate with nothing but the fuse burning.

50 years ago Standard Fireworks used to make those out of a small strip of cardboard and a small rocket motor. Designed to be used in the standard (no pun intended) terraced house back garden. They amused a generation of fathers and terrified a generation of small children as the watching family would have no idea which way the highly dangerous toy would fly off. It would elevate to cry’s of ooh’s and aah’s and the occasional “look out” as it would hit buildings on its way up. If only we had KZfaq when we were young….. and CAD printers may have been handy too!

Suggestion: A rocket powered car. But not in the way you'd expect. A gear gets spun by rockets (like the mono-copter) and that connects to the actual wheels moving the car forward. It's an idea of the wacky type

So I have some potential for improvement here.... possibly. It sounds like, purely from the sound, the helicopters are rather quickly reaching their maximum rotational speed and then staying there for a while. From my knowledge of rockets, the thrust they produce is basically a function of the exhaust gas speed vs the forward speed of the rocket, especially when you're in an atmosphere. So my thought here is that possibly the rockets, with the arm length and rotational speed, are reaching a linear speed that's basically equivalent to their max thrust minus however much for drag forces. So hypothetically you could get it to rotate even faster by putting the rocket closer to the center of mass of the unicopter. You could probably pull that off by having the arm extend past the rocket's position and act as a counterweight to the main wing, and possibly even improve the lift by making that counterweight a much smaller wing. The other alternative is that the linear speed issue is negligible compared to the sheer drag of the whole system, at which point I wonder if you could get better performance with a larger, slower, more efficient wing design. Or even a 2-stage system. 2-stage rocket unicopter would be amazing.

This rocket-copter is sick! Could you do a rocket powered dragster in a future vid?

Rocket powered submarine. Yes, you heard me.

Die cast rocket car, fastest die cast car possible

Monocopters! There have been some pretty insane large ones in the high power rocketry world over the years.

This is basically what the bee firework is right? Altough that is better because it has less rotational inertia. Still pretty cool though.

i believe they make fireworks like this with a side exit exhaust. Basically a modified ground bloom that takes off into the sky.

Did this when I was a kid in the 1970s. No 3D printer, all built by hand. I got the helicopter ideas from spinning fire works. Made all kinds of things using wood and sheet metal and rocket motors. History repeats itself.

The weight of the engine changes as the fuel burns. I think a multi-stage rocket plane with these motors would be fun to watch.

If you can lock it in place temporarily(fraction of a second) until you can light both motors, seems like a symmetrical 2 motor rotorcraft design could fly in a more balanced way, and go a long distance

The first thing I was thinking was actually "Yes you can, they make cheap fireworks that are literally cardboard, rocket-powered helicopters" but still, cool footage and cool project!

Yeahh!! That's my video 0:30 Very interesting project! I see the resemble of maple seeds falling. I love to watch them float, parachute, tumble, spin and glide to the ground as you explore the aerodynamics of seeds. Awesome project!

There's now a downloadable project kit for this rocket helicopter! Check it out ---- store.projectair.co.uk/products/rocket-helicopter

Barely pitch the engine-mount angle, as opposed to now relying entirely on the engine solely to rotate and the blade's ability to lift: separately, the prop-blade, perhaps a single triangular wide-tip fan-vane would better balance the thrust into lift.

Your enthusiastic face makes me totally believe that having "no control whatsoever" is the most desirable feature on earth

I like the helicopter projects not many are done but they are fun to watch.

I love these little projects! Nice design!

As the propellant burns the center of gravity/rotation will change substantially. I wonder how much the RPM changes. Perhaps making it stretch out as the RPM increases can compensate for this?

I wanna see a rocket-powered craft that launches into the air like a rocket, but then safely lands using pop-out propellers to spin. Awesome video!

When I was a kid my father gave us puddle jumpers. They were a airplane propeller glued to a stick in the middle of the hole. One swipe of your hands to spin it and up it went!!! Tons of fun for hours. Maybe you could somehow incorporate a stick of some sorts for stability. ❤️the channel

Love ur vids. They are really good and all of your creations are awesome. Keep up the excellent work.

i would love to see a rocket powered and steered plane

the dual motor version might have worked if you locked the prop until both motors fired up and then released the lock. a simple dowel or steel pin might do.

The civilatory project is alive. Men like you are important. Thx!

That's freakin cool! If these were scaled up, had a dome in the middle where a pilot would sit, it'll be very steampunk 😁

I would like to see a retro rocket parachute. This was attempted during WW2 with little success, but more recently it was used on the Mars mission very successfully. This will be a challenge!

The seed works so well because of the heavy weight ball that becomes the centre of rotation it helps stop the side to side pull of the mono blade so if you can replicate that a bit better on yours it might go straight up just an idea

Outstanding shipmate. Press on. USS Kitty Hawk CV-63. Jan 1980 to July 1983.

i thought the thumbnail was clickbait lmao

How about one of them folding rocket gliders that snap open at the highest point of their trajectory?

6:00 POV you’re an archeologist 1,000 years in the future. Your plastic detector picks up something, so you dig down and find this thing buried in the middle of an old forest. Wth do you do lol

You just reinvented a $3 firework that’s been around for ages…but you did it with style.

Possible idea: Use the expanding gasses of the rocket engine to drive a steam engine. The idea is quite interesting and the modern vs old fashioned tech contrast is also nice.

3D printers really are amazing. I have literally thousands of hours on my original ender three and I have yet to have a single mechanical failure that wasn't my fault.

the single blade design is cool because when the motor burns and it autorotates back it resembles those seeds of a maple tree that are very similar and autorotate down like that.

You did what I used to wonder about doing. Especially rocket motors along the sides of a plastic propeller.

Long burn, multi stage rocket planes would be cool! Like, one high powered slow burn to take you up, then some longer burning, lower powered ones to keep you aloft when you need more speed/altitude! Keep up the good work dude!

If you can fit a gyro into this with a vibrator motor and a data logger you'll be able to work out a waveform that you could use to be able to steer it. Don't abandon this concept. It's very cool. If you can find a way to control it it'll be mind-blowingly elegant and you'll have started a whole new thing.

That moral support from Cow spectators was very motivating

If you revisit this, the optimum is with the rocket thrust vector angled somewhat downwards. Similar to how jets in cruise are a bit nose up, the best use of thrust and lift is mostly lift but with some thrust.

Lockheed Martin did this about 15 years ago, there's was about the size of what you did. It was classified for a long time and then the project was scuttled. The engine was "grown' on a copper chip and I was a VERY small turbine engine. It had a camera on it that was able to compile a 3D scan of a battlefield, or even a building. They also figured out how to equip it with a small explosive charge that would have been lethal. It was able to be steered using control surfaces and the engine was able to vary it's output rapidly to change course, hover and fly. Really cool tech, I know the guy that designed it and I did some of the machining on it myself.

"Check out this 1950's technology!" IIRC, Hiller developed a bunch of small, one man helicopters that used rocket or jet thrusters at the rotor tips.

Thanks for bumbing that into my head while I was peacefully coming back home with groceries

You have made a flying knife, this is mad

For those wondering about the difference in the "rotation point" versus the centre of gravity, you can start your journey by looking up "Moment of Inertia" (Sometimes called "mass moment of inertia"). This has to do with how much "resistance" to a change in rotation speed there is around a certain axis of rotation. As defined by wiktionary the centre of Intertia is: "A point, near or within a body, at which the body's mass can be assumed to be concentrated when considering its rotational motion and moment of inertia. This may be different from its centre of mass which is the equivalent for linear motion". The reason you can't take the centre of mass as the centre of rotation/inertia is that when calculating the centre of mass you are "assuming" that all the equivalent mass of the part is concentrated in that infinitesimally small point. This is valid when you are doing for instance linear calculations with forces acting on this point and causing it to accelerate (using F=m*a). However, when you are rotating that same part AROUND a point, not all that mass acts in that same point the same way. Bits further away take more force to accelerate (longer arm=higher torque to reach the same angular acceleration=higher moment of inertia) than bits closer to the axis of rotation. So when looking at rotating bodies you're looking for the point where (for that particular axis) all the mass around it has a moment of inertia distribution equivalent to a simple disk, so that it rotates around that point in that particular axis. Probably not the best explanation, but it's been a while since my Dynamics 1 classes ;). With the above terms you should be able to find more info on the internet from people smarter than me and better at explaining it. For things with a relatively even mass distribution, you can often find the centre of inertia relatively easily by making a simple cardboard cut-out silhouette of a "view" perpendicular to the desired axis (so that the axis of rotation is pointing straight "towards" the viewer), bend it so that it has a slight and even curve with the ends slightly higher, then try to spin it on a flat surface. If you can get it spinning like a top, it'll naturally want to spin around the centre of inertia and you can see where it is quite easily visually, especially if you put some pencil lines in the area.

The spectator cows at 6:28 are the absolute best! 😃 Awesome video!

We had these as a kid in boxes of fireworks . All they were was a bit of cardboard with rocket motor stuck to one end , to launch them you would put them on a sloping bit of wood or as shed roof , light and hope for the best.

Just wanted to say thanks for all these awesome videos and to keep up the rocket propelled projects

This is awesome . Thanks for MORE ROCKETS

I love how in the beginning his reasoning is “ I know it’s dangerous and potentially lethal, but hey.. views!” Fair enough my friend, you earned a new sub 👍

Brilliant video .... thank you for making me smile and inspiring me to fun stuff with rockets... My wife just shakes her head and calls me names .... So I put that down to success...

Rocket powered fly swatters. 😂 we need to see this. Lol

I'll tell you something mate first of all well done on all your projects because I absolutely love them..your amazing my friend keep doing what your doing..after all at least your motivated to the core...take care pal 👍

Just discovered your channel tonight. I must say there are some very imaginative projects on here. Too bad that you're on the other side of the pond because I would love to watch in person some day. Best of luck, keep up the good work and above all have a happy and HEALTHY New Year.

You can actually make these by taping a cardstock wing to a ground flower (the spinning firework) In places where aerial fireworks are legal they sell them premade

Just looks like a butter knife flying through the air, really amazing concept.

0:12 "I know what you're thinking." My head: 🎵HELICOPTER HELICOPTER!🎵

the cows in the backround are just like "huh, whats that guy doing" 6:34

Ah it's great to see quality Goblin trap making. Well done good sir many adventures will fall to these flying lobotomy devices.

How about converting some old Jetex designs to the TSP rocket motors? And then, if that is to boring for you, you could try some multiengined designs. The 25" Skyleada Vulcan with 4 TSP motors (and maybe also converted to RC) would be so cool.

For electronic ignition wire from a vape does the trick perfectly. 2s/3s battery will light off but you would want more of a timer as 2 seconds lights it but 6 seconds burns it. For rotational mass issue you should look further at the angle of attack

6:33 Those cows are totally immune to this crazy humans antics at this point haha

Dude you totally HAVE to build a giant one!!! Like NOW!!!

Rocket powered drone. 4 monoblade propellers, ~30sec flight time, rocket powered performance. The Me-163 was built with the "insane lift ASAP" problem in mind, so Im thinking a Monocoptor based drone version of that.

To fine point of rotation take inspiration from maple seedling pods. Mother nature already made a monocopter. Also the 'stick' or launch rod. Make it longer so copter can build up speed before takeoff.

When you risk your life I respect your dedication.

Thankyou you just invented "The Rocket Powered throwing knife" all you need is a centrifical switch to set off the igniter and your set...

I really appreciate the videos you make. Wonderful to share interest of aviation and rocketry. 👍

That is pretty cool! I have an idea for the next video, maybe you can make an RC plane that is powered from that helicopter

I wonder if you could get two motors to more reliably ignite if you used a hold-down clamp that released like 1/4 second after ignition. That way the first motor to start doesn't rip the starting equipment off the second motor before it ignites.

Rocket-powered baby. Definitely.

Tip a rocket with a few rocket spinners as payload. Have the rocket parachute deploy and light one or two these so that it gets a bit of auto rotation before zipping off. Attach a few LEDs to them and launch at night.

Nice. Nothing could possibly go wrong doing this! I wonder if the stability and overall performance would be enhanced by adding a fly bar.

Are you sure the guide rod is long enough? Is it spinning up to full speed before leaving the rod? How long do the engines take to ramp up to full thrust?

Interesting to see that even a lit fuse provides some measure of thrust - never expected that although it makes sense now

Super idea for making this

I fly these every July. Near the beginning. They cost 2-3 bucks. I’ve also been working on developing a stick, that is rocket powered. I gave it a red paint job and can fire it from a bottle.

Cool murder wing! You should make a 'nos' boost for a 'racing drone' with your left over rockets see if it gives it a decent acceleration!

I always wanted to make an RC boomerang. This is a good start.

Great work, those look fun

It's been done before. Hugo Nagler invented a single counter-balanced blade helicopter way back in the late 1920s and carried on with his research into building single counter-balanced blade helicopters during WWII. In 1941 he invented a single-man portable helicopter that had two blades driven by prop-motors mounted parallel to the roter's direction of spin. This eliminated the need for a counter-rotating tail rotor. In June of 1952, Nadler filed a patent for a helicopter with rocket-powered blades.

"want me to make more rocket themed projects"?? I cant believe you have to be told such a thing. Everything at all times should always have more rocket themed projects. If theres only one certainty in life that you can always be sure of to bring enjoyment and satisfaction, its rockets and their themed projects.

How did I miss this vid. This is epically awesome

Genius bro as soon as I saw it fly in the first few seconds I immediately wanted to know how the heck you did it.

Aaaah yes, the classic launching burning things at trees content

That’s amazing

Next? How about a "normal" RC fixed wing plane but (multistage?) Have the motors ignite sequentially. Obviously the trick is in timing the next motor. Rather than wicks of different lengths, perhaps a servo, actuator, small "fuse" resistor in each motor that burns when needed on a rotating switch controlled from an RC channel, etc. As the plane is just gliding, ignite the next motor, etc. Just a thought. As a goal you might go for altitude per number of motors. Keep spiraling upward until you run out of motors and keep gliding. Nice work, BTW.

Well done enjoyed this immensely

This is how you make a helicopter in a game with no air physics, put thrusters on it and pretend it's a regular heli.

A suggestion, a rocket with folding blades that pop up when the rocket comes down, so that it can decent slowly like a gyro copter.

Imagine adding a slight angle to the rocket motor so that it pushes upward ever so slightly. But only maybe 2 degrees or so.

Rocket powered impact sled testing 3d printed structural bridge and lattice diagnostic. Like car crash testing for 3d printed support style stuff. Maybe even with a press and force meter?
