My jaw literally hit the floor when it lifted off the tripod for the first time 😂 mind your neighbors cows don't get decapitated! Excellent work as always 👏
can you upgrade you rocket and make a rocket glider? this rocket with retractable leather wings wich is open after the rocket have an null velocity height after than vertical take off. you can glide it down with fpv cause you stabilazer controlled. lets make it - you idea!
James, we can totally stabilize this to give you roll/pitch control! A reliable yaw heading with yaw gyro and magnetometer (MPU9250) can give azimuth while in flight, then throttle can be modulated around the azimuth to increase/decrease lift on one side and stabilize on desired roll/pitch angles. Hit me up this summer (after my exams are over haha)

As a former helicopter mechanic (UH-1H), I applaud your efforts. Trying to get a helicopter to fly really gives one an appreciation for Igor Sikorsky. And remember one of the basic flight concept of helicopters: They don't actually fly, they beat the air into submission.
@@Project-Air i think i can say that i know that feeling, i daily drive the japanese twist in the form of a mazda mx-5. i probably don't need to tell you that a 30y/o car gives trouble sometimes (my brake literally started steaming just today), but my goodness is it nice when you can just enjoy the drive.
First, way cool! I’m a 70 year old retired physicist and when I was a kid was always throwing helicopter seeds (they are called samara). I often told my students to think like they were five and they would appreciate a ton of physics. You looked like you were have lots of fun. Stay young in mind and spirit!
This may have already been mentioned in the comments: A very similar helicopter to this was published in the 1960s in the magazine, "American Aircraft Modeler". The helicopter at that time was called, "Charybdis". It was powered by a Cox .010 "gas" glow plug engine. Construction was almost entirely balsa wood, harder wood for the long arm and a thin, plywood plate upon which to mount the engine. Now, carbon fiber and 3-D printing. My, how the times change. I think you deserve a lot of credit for your hard work, determination and perseverence. Thank you for this video. You put a lump in my throat as I reflect on the balsa wood models of days gone by. Best wishes.

3:00 Nice seatbelts these are very secure, but since you wear the cap in the proper orientation you may consider to mount some headrests. In case of a accident you may hurt your neck. Or snap it, and that is a no fix :). Cheers.
I built one of those single bladed copters about 45 yrs. ago. Used a Cox .010. I still have it. Mine got launched by hand. Spin, pushup, let go. It took me about 10 attempts to get it to keep flying. The spinning The centr. force over pressured the fuel and caused it to run rich and lose rpm( and altitude! ). I had to tune it beyond the correct ratio ( too lean ) then spin it to launch. The rotation brought up the fuel ratio and it flew. I lost it on the first flight, but found it a year later, 80 ft. up in a tree several blocks away. Back then it was called "The Charybdis". Plans from Popular Mechanics. That was it's only flight.
Tom Stanton is a patreon of yours? You should do a collab! And regarding your helicopte: There is definitely space for a knife at the tip of the wing:P
Wow, Thats very amazing . Keep goin . Remember center of balance + center of gravity + center of drag . If you figure out how to put all in the same spot, you will have it. Good lock.
Thank you for the Ad - Progress Bar. It helps prevent impatience induced click-by. I watched the ad any way because I could see it wasn't going to "27" hours long.. heh =)
Beautiful experiment! To find the dynamic rotation point: Tilt the helicopter wing such that it does give no lift. Glue a piece of light carton underneath on the helicopter frame in the zone where the dynamic rotation point is expected to be. Hang the helicopter (close to static balance point) with a long rope to the ceiling. Start the helicopter and let it run at the expected flying RPM and touch the carton from underneath with a marker. The helicopter will draw a circle on the carton which center indicates the dynamic center. Attention: dynamic balance point moves by varying the RPM!!!, so try to simulate with +/- the specific flight rpm!!!. And giving the wing a progressive angle would make the flight MUCH more stable and more efficient!!!
On another topic entirely, congrats on the classic Mini! I’ve been a British car fan for ages, and have owned an MG Midget for almost 26 years. I also helped a friend restore a Mini, so I have some familiarity with them. Will you be coming to Flite Fest this year? The anticipation is mounting. ;-) Cheers from Missouri, USA.
What a wicked helicopter!!! Watched the videos in the links.... this wasn't possible 15 years ago. Mind blown! Thanks for the info and video, good stuff!
They made choppers like that back in the 70's. I was not around, but they would make freeflight timed with burning wicks and a switch, r/c ones that had a heli fuselage hanging below to hold a pitch and bank servo, simply pulling it forward from just below the bearing that held the blade to the top, and some had a servo to control a reversable brushed motor powered tail rotor, that would move the tail in yaw to direct the nose, since there was no torque created by the rotor powering itself. They also had the most annoying type- a main rotor mounted gas engine, spinning an oversized prop, then the torque would spin the whole rotor blade the opposite direction. In a world of gps programmable flightpath and gyro stabilized drones, it is way more fun to tame a not so automated contraption.
Pretty fantastic work, James! 😃 I don't know why, but one of my cats kept watching everytime the helicopter turned on! 😂 Anyway, stay safe there with your family! 🖖😊
Add another pole at the center, pointing straight down, such that the weight tends to keep the plane of the blade's travel horizontal. In fact, you could launch it by sliding the pole down into a vertical pipe, further ensuring that its horizontal upon launch.
You can make a slightly simpler helicopter by eliminating the wing and tilting the main prop mostly upward. Thus, it's basically a spinning mono-rotor ... one fourth of a quadrotor. The countermass can be an L shape - a bar with a bend. The important adjustment is tilting the motor/prop so it works well. You show an example of this sort of thing at 7:37 - notice how it just has the one prop and everything else is essentially a shaped countermass to allow it to spin in a stable manner. The other bits aren't aerodynamic at all, everything useful acting on the air is the prop.
Wow now that makes sense so basically use your battery for counter weight so all u need is balance your battery & moter with the proper angle &your flying
@@beachinrc101 Yeah, that can work particularly well if the battery is long and thin. Basically, you want the weight distributed along a plane rather than just along a line. So, a T shape with the battery along the top and the prop at the tip of the bottom can work well. The point is, the planar weight distribution forces the body to align perpendicular to the spin axis. This in turn forces the prop to be pointed in the desired "upward" direction.
Maybe try matching the center of rotation and center of mass and then sticking a thin stick down the whole aircraft? Then you could use a "launch tube", stick the stick into it and then launch it from there.
I love these videos, down a shot every time you see: A 3d printer, a drone, a slow motion camera, liquid Nitrogen or Aluminium, a swimming pool, a suspiciously bare room that has been repurposed as a studio, a computer you cannot afford, and an immaculately mown lawn, to test the inevitable aeroplane on. Tom Stanton is one, BPS Aerospace, TheBackyardScientist, The King of Random. You will be bladdered in very short order.
Please put a video on designing the CAD and some tips for designing an accurate design. This would be good. Try making a series, like Designing(CAD)>Body>Avionics>Fuel(Motors)>Recovery>Launch..... Seems quite long, but may fetch a lot of views and subscribers............. Thank you for your videos..
Some how I was reminded of a Dog chasing its tail and like the dog it gets dizzy and falls down I also couldn't help to notice that the Cows had the good sense to hide in the trees....... Good Boy.....sit...roll over....Good Boy...
I think you could add directional controls to this with a single servo controlling a hinged control on the wing. An arduino combined with a MPU sensor would allow you to initialise the model on the ground and define "forwards". You would then have a fixed plane of reference that you can use to control the model meaning you could then code "aileron" and "elevator" controls by mapping the input requests so that they activate the servo at the appropriate times in the rotation.
Very impressed by the stability achieved here, I wonder if the same principles could be applied to some kind of RC boomerang since they utilise similar ofset weights to generate their lift.
I used to build these with Cox .049 engines. It had a horizontal stab above the wing with an adjustable elevator to control the pitch of the blade (speed of climb). No throttle, just watched it fly until it ran out of fuel.
Ok, so James, I like the Guillotan Heli. I am almost positive the US would buy them if you make the blade stainless and slap some paint on.😂 I LOVE the Mini though. You've been holding out! They're hard to find here, but I do have a '74 260Z that will be sick. Hopefully when you make it back over she's ready! Keep the content coming, always great. Cheers mate! -Jody

Далі - стпробувати керувати кутами крил для зміни кута атаки до повітря. Може, навіть з'являться ідеї на основі даних з датчиків: гіродатчика - отримання вектору обертів (опосередковано енергія яка ще є в наявності) Гавідатчика - отримання опосередкованного розуміння положення відносно землі.😊
If you get the balance figured out and build a larger winged one that doesn't need to rotate so fast I think you would be into something. Simple enough to build from a kit and when the design becomes stable it could be a lot of fun.
Hi great idea. I used to have a free flight helicopter with a Cox pea engine and once the engine was running the counter rotation would spin the outer blades when it got up to speed the blades would start to alter pitch with a counter weight on the blades so you are not wasting lift for drag when the blade is set pitch
Might want to see about hanging a heavy weight from the center of the tripod, if you're going to use that method to launch, it'll help stabilize the tripod, and perhaps make launches a bit more predictable. Also, the heavier the better within the capabilities of the tripod, and also keep it pretty low (almost touching the ground.) What this will do is lower the center of mass of the tripod as low as possible, and make it much more stable relative to its height. Good luck :)
Well done! A free flight version was featured in "Aeromodeller" or perhaps "Model Aircraft" magazine (UK) in the 1950s. It was called a "Charybdis" (after the Greek Χάρυβδις, a mythical sea monster or whirlpool). In those days the power was a 0.75cc or diesel engine which developed all sorts of fuel supply problems spinning around on the arm opposite the wing.
I actually built one back in the 70's - still have it (but it hasn't flown in decades). Used a Cox glow motor for power - launched (as I vaguely recall) by holding it above my head and simply giving it a twist. It would climb until engine cut, and then auto-rotate down.
This reminds me of the Fairey Gyrodyne design of the 50's. It used tip mounted jets supplied with air from a compressor in the body of the airframe. It flew very well, and was only let down by the ungodly amount of noise it made.
Here in the UK in the 70s we used to have a firework called a helicopter. It was a bit of card about 4x1 inches with a rocket motor tapped to it about two thirds along, you would then launch it from a shed roof or a piece of wood at a angle, the fuse had to face you when you lit it. Maybe you could make a modern version with a ducted motor.
Looks like the "Charybdis" helicopter published in "American Aircraft Modeler" magazine back in the 1970s. That one wasn't R/C, it used a Cox .010 glow engine. Never built one, but I still have the plans, and an .010 engine, in a box somewhere...

I actually built one back in the 70's - still have it (but it hasn't flown in decades). Used a Cox glow motor for power - launched (as I vaguely recall) by holding it above my head and simply giving it a twist. It would climb until engine cut, and then auto-rotate down.
This reminds me of the Fairey Gyrodyne design of the 50's. It used tip mounted jets supplied with air from a compressor in the body of the airframe. It flew very well, and was only let down by the ungodly amount of noise it made.
Here in the UK in the 70s we used to have a firework called a helicopter. It was a bit of card about 4x1 inches with a rocket motor tapped to it about two thirds along, you would then launch it from a shed roof or a piece of wood at a angle, the fuse had to face you when you lit it. Maybe you could make a modern version with a ducted motor.
I mean, the world's simplest helicopter are maple seed's...
Edit: i just realized he said it himself in the video...
Beat you to it 😛
It's durability is most impressive!
I was pleased to see it could handle some abuse!
Cool ! I love your ingenuity.
Yooooo that’s an epic mini
AMAZINGNES!!! What a interesting wierdly sound it makes.
Its remarkably stable and fun to fly. WowWee blade star.
Rule number 1: an RC flying machine will always fly towards a fence! Otherwise you have done some brilliant engineering. Keep up the good work.
Rule 2: an RC helicopter can sense fear and will chase down any operator who backs away
I like this idea
Btw, its like rc boomerang
Good to be back, have been waiting for you, sure you can💯😎
Looks like the "Charybdis" helicopter published in "American Aircraft Modeler" magazine back in the 1970s. That one wasn't R/C, it used a Cox .010 glow engine. Never built one, but I still have the plans, and an .010 engine, in a box somewhere...
