Manned multicopter build part 10 Takeoff at 4:40 Fuel consumption is 0.65-0.7 liters per minute. Shaft power in hover around 30kW. Thank you all for the encouragement and kind words, I really appreciate it. /A
Lower your CG and you'll get a much, much more stable flight. She's a top heavy girl, if you could bring your body weight below the props you will notice a lot more stability in your design. Aside from that, great job!
@@BK-hq7tn that video misses the mark, if he put weight above the rotors to demonstrate the opposite effects (like in this very video) then those of you who don't build aircrafts would get a better idea of what I mean
Wow! Congratulations! May I give some suggestions? Most concerning your safety: - Have a friend with you, when doing first flight experiments. - Keep the propellers of the ground -> place them above your head. - Reduce ground effect -> place the propellers above your head. - Bring the center of gravity down, for stability -> place the propellers above your head. - Bring the propellers away from you body -> place them above your head. - Prevent engine brake down -> look at vibration, I think they are shaking apart. - I would prefer electric, but I understand your choice. And a question: are all 4 engines non-steady? If so, would it maybe work better to keep the inner 4 constant and the other ones variable? Keen going pioneer! Giesbert
This is awesome. Please do add 4 leaf springs to the bottom (2 on each side for stability) so that in the event of a fall from 6 feet, you wont break your back. I don't want to see you get hurt. They could also work like skids. I hope you're wearing some ankle guards.
This is brilliant! Not necessarily the most practical, and scary as hell with all those massive finger hungry props surrounding you, but it's certainly quite an achievement to have made this!
Why are people putting him down? This is how great inventions are made, by someone in his shed in the garden. Left to you health and safety pansies, you would still be living in the cave wondering whats over the horizon.
A quote from Wilbur Wright for you - “More than anything else, the sensation [of flying] is one of perfect peace mingled with an excitement that strains every nerve to the utmost - if you can conceive of such a combination.” - I'm guessing you can dude!
Very good idea but there are some obvious problems with the swing of the drone, this is because when putting the chair on, the horizontal center of gravity is very above the base, so the system will have to be making corrections permanently. I would suggest lowering the center of gravity to achieve good stability, or raise the engines to the midline. Very good idea, congratulations
Amazing! A fantastic piece of machine! Ignore all the safety junkies.. You estimate the risk and do what you feel comfortable with. There will always be ppl telling others that what they do is wrong in one way or another...
I love it! I think if you put your cockpit under the blades and you were to ride under the blades, your stability would be amazing! Keep up the good work.
I admire your resourcefulness. Respect to you!However, in it's present form this machine is a perfectly designed deathtrap. You should call it a total success as a proof of concept design and dismantle it. If I might suggest for your MK2 Design:--- Retain your engine mounting platform and suspend your seat below it on a flexible mounting.--- Using your body weight as a suspended pendulum will allow you to use handlebars on the bottom of the engine platform to control flight direction, much like some hang gliders. This will give you increased stability and faster and more simplified control inputs. --- Moving yourself out of the plane of rotation of the propellers improves safety.--- Install duct around the props. This will improve efficiency AND safety.--- Suspending your seat below will permit the use of a shock absorbing structure to absorb some of the damage when you land hard.--- mount a race car fuel cell type tank ABOVE the engines to dependably gravity feed the little monsters. Operating a aircraft at very low altitudes is always going to involve greater risks. Designing your aircraft to save your life when it's in Failure Mode is just good engineering. Remember, Gravity Gusts and Altitude Deficiencies seem to occur at the same time.
Amazing job. Don't worry about the negative feed back. If you could afford to design extra safty features, you obviously would. A anustable pitch prop setup would undoubtedly be out of your price range. However, ducting the air flow of the engines would not be. I would sugest large servo controlled air flow obstructers to control thrust output for each power plant. Alowing you to maintain a constant rpm "collectively" while giving you more stability and control. Great job, sir.
It needs a better suspension system to protect your spine from injury in the case of drop from two metres "altitude". What about mounting the chair on air bags of some kind, minimal weight but it could protect against a nasty injury, compressing air is better than compressing your vertebrae.
Dude. This is so awesome. My first thought is having the blades above you might better stabilize you with your body weight below. Less top heavy in a sense. Solid work though. Absolutely love it.
That was AWESOME! I thought we were heading for a trip through the woods when you showed the flyers perspective . Come on let's go!! Two feet off the ground and zipping through the woods? Hell ya! LOL
I love this buddy ...awesome video ...don't listen to haters .. they are jelly for real because u can fly high on a chair wile there chair is planted in front of the TV watching u ... good job brother ... I'll keep my eyes in the sky looking for you soon ;)
Hats off to those daring young men in their flying machines! Seems like a lot of things have to work flawlessly...I hope there is failure protection engineered into it. Enjoy the flight!
My hats off to you mate even if I dont have a hat lol, I had a huge grin watching your amazing machine hovering, I fly freestyle fpv 210 size quadcopters and you have made what I dream of although I would rather go electric but obviously the battery tech is not quite there yet, hopefully the next gen batteries will allow that, I still want to have a go of this, what a rush, great work!!!!!
Thanks, yea, next generation battery tech will make small and usefull man carrying electric multicopters happen on a large scale! Looking forward to that :-)
That's pretty cool, good work. I feel like one built with a huge array of powerful DC electric motors controlled by an Arduino and powered by a big deep cycle battery could be more reliable though? And probably get more flight time. It could also be made to hover and stay level automatically by using a gyroscope, accelerometer and good coding. There would be no need to manually keep it balanced. It would go a long way towards safety.
If you had several million dollars to spend on R&D and a team working on this, I can't imagine how far you'd be. Very cool. Good luck fine tuning. Once done, sell it as a "Home built".
Hello. I accidentally saw your video and it's a great project, I'm sure! If you don't mind, I would suggest the following 2 improvements(if you would consider them please let me know, to subscribe to your cannel): 1. reverse the engines and propellers directions to down(also rotation must be to make this possible), in order to improve lift efficiency and security in case of accident(propeller or bad move and dropping on propeller) 2. together with idea #1 or alone: set 3-4 light rubber ballon wheels(as in airplanes wheels) with springs, to avoid crash landing damage to you and the machine 3. it would be amazing to implement a gyro (Arduino maybe ? :) ) controller to control each engine independently, based on its efficiency and necessity in running , this would offer you the next step for moving forwards and stay put with no effort. With a little automation, you could compute the efficiency of each engine and make the apparatus a perfect flight machine. 4. I don't know, but your seat can be from extruded foam, very light and strong enough 5. suggest you wear a helmet 6. also a big step would be to be able to rotate the angle of the propeller/engine forwards and backwards, to support speed flight and more forward power combined with lift support Good luck and hope to hear from you! Bogdan
Lovely! I would incorporate the safety seat from this machine, with the other electric machine. I would also place a air bag under the seat - For reference, some paraglider harnasses have this feature. In my opinion your electric copter is the best one on RU-vid at this time!
I would highly recommend extending those arms out further. That should help smoothen out your thrust issues. More of a circular motor pattern would be more practical. But otherwise a wonderful build :-D
Ok I will tell you the same thing I tell all u guys trying to do this. Put props above where you sit this will make it a lot more stable and easier to fly Your putting all the Weight on top and making it top-heavy and off-balance basically you're making it want to flip over but by putting props overhead it will naturally balance out. keep up the good work
Also, the combustion engines just don't change revolutions fast enough while in operation to make the corrections more precise from the rotors thus improving stability
keep in mind he starts the engines (from the top) *before* he gets in so having all those props running at neck level might be a little nerve wracking for some people.
HormigaZ the gas engines he uses are a bit small it would be beter to use 8 larger gas motors with bigger props 4 arms 2 motors per arm So if 1 motor fails you can still fly down safely. Now gas is beter for longer run time is a must for now & you will need some1 to make him a good Computer motherboard to control the power to the motors The same type of motherboard used in say a phantom drone with self-leveling technology But still props should alway be above the pilots head . The weight needs to be under the props for better stable flight I saw that one guy on. RU-vid has already done this eight engines but they are electric they are above him and he sits in a super small canopy but if you watch it you'll see it is much more stable
Fixt100 look up " Maned homemade drown " & you will see a guy who built a drone with props above the canopy that he sits in it is very stable but because it's electric it doesn't have a very long run time
he needs a system like those new drones have that transfers the weight after takeoff (to stabilize the camera) wouldnt even have to be powered just moves up and into an overhead position when he releases the lever on the hydraulics and applies throttle.
I applaud you man. a few more safety touches and you may have something special👍. and all the nay sayers never had the smarts to try something like this. so keep thinking I love it.
You need the props above you dude. Your center of gravity is way to high and makes the octacopter unstable. And you need to bring the middle 4 props out more so is has more left and right pitch control. And some landing gear to absorb the landing Other than that pretty cool dude well done!
What sensors do you have? You could probably achieve greater stability through the flight controller. Until it hovers and flies like it is on rails without a passenger you shouldn't be onboard. Fly by radio or mavlink or something. Second, aside from safety issues, mounting high above the head would help you avoid prop wash and ground effect when taking off.
looks like you found the sweet spot for it. Time to take it for a spin :) The best time to fly it is in the morning or evening when there is not much thermal activity I can hear the sweet spot the engines are more relaxed and not making so much noise heads up
You should make body kit for it. One way to get the craft more stable is to make a ring covering around the blades so wind isn't throwing you off balance. I think it would be really cool if that happened
Sir, I like you're creativity. May I make a suggestion? Add a slight safety cage in case you land off center damaging a blade then possibly having it injuring you. Maybe a simple helicopter landing gear set up to take an abrupt impact from below. Keep up the good work.
It is a very cool and dangerous project. You should have sacrificial landing skids to absorb a hard impact. Lightweight foam would help soften a hard impact. Another idea would be to use an autogyro blade on stop to give you lift in forward motion and if there is a failure it will slow you to a landing.
Don't use wireless controlling system, please. when your radio fails this machine won't work anymore. And please use some prop covers. Good luck and be careful!
I’m certain that you must have considered mounting the motors above the pilot’s perspective even mounted on a restricted gimbal arrangement. This might result in more of a simulated feel of a conventional helicopter experience. It would appear to create a more stable flight characteristic. I shooting in the dark and would assume that you have been down that road and many others in the course of your design concepts. Truly remarkable! You certainly have a great degree of courage. The top mounted propulsion platform may even add some degree of auto-rotation capability! Just thinking out load! Both of my hats are off to you, sir.
Its great to see you getting better flight times. If I could, 2 suggestions. (1) someone earlier mentioned a roll cage, great idea. Second, redundancy, start working on remote in flight engine failures, what would be required to compensate! Safety first.
If the operator during flight or while the Motors Blades/Propellers are in rotation,if an impact occurs that would shatter the Blades/Propellers and propel the material in many directions and cause major damage to others or bystanders,an if you build a Cage correctly if there is an impact with the Cage/Guard the object would be stopped from impacting with the Blades/Propellers and thus avert a catastrophic condition ,and a hard enough impact would just house the material within the Cage/Guard.PS also if a guard is on/in place that would work as a bumper,during flight if the operator accidentally at slow speed impacted against a Tree as an example the guard would take the impact and not the Blades/Propellers themselves
Just got my first rc quadcopter.... crashed it 10 times and lost it on the neighbors roof on the first day. They are hard to control... this guy is nutz.....kookoo.
nice work but you should put some kind of safety shields around those blades and widen it out some.those blades look as if one slip was to happen you will be sliced up.
What a great day indeed! I can't believe you can walk around, let alone wear normal pants ;-) This project is amazing in so many ways, congratulations and thanks so much for sharing!
Landing gear with springs and shocks, saftey cages on motors, saftey cage for pilot, air bags, four more engines, more fuel capacity, and other stuff, and I'll want one to commute to work in.
2 suggestions.a. Mount the engines overhead. Much more stable.b. Add an Arduino controller.With that, you can make the system: 1. remain level... it will automatically maintain levelness. 2. maintain heading... it will autocorrect any heading drift. 3. maintain altitude... no more up and down jitter. With all three movements automated, when you elevate to a given height, then release controls, it will stay there rock steady.BTW, nice design, especially the seat.
IMO, this aircraft will not be viable until it has computer synchronized rotor speed control and some form of automatic stability/leveling system. The motors are all rotating in the same direction. Part of it's instability is due to this aspect of the design. I would have divided the motors in to quadrant pairs and counter-rotated each motor in each pair against each other but matched rotation with it's diametrically opposed pair. Also, I don't understand why so many people keep designing these multi-rotor aircraft with the center of gravity above the rotor plane instead of beneath the rotor plane as the latter is inherently far more stable (and safer).
