DIY Flying bike - Motorcycle to Hoverbike - Modified version
Вставка
- Опубліковано 19 лют 2024
- Hello, friends!
In my previous video, I shared with you the process of creating a Hoverbike that was supposed to lift off the ground by a few meters and hover in the air. Unfortunately, we didn't achieve that goal at the time.
Many of you wrote to me suggesting that I should modify it by adding electric drone motors for stabilization, and others mentioned that the propellers should be repositioned higher than the center of mass. Well, I decided to take your advice and have now revamped the Hoverbike, with the propellers now positioned significantly above the center of mass.
What do you think of this version?
Please share your thoughts in the comments, and don't forget to share this video.
For those who are seeing this video for the first time: this project is about transforming an ordinary motorcycle into a Hoverbike, aiming to merge the thrill of motorcycling with the cutting-edge realm of aviation. Join me on this journey of innovation, where we explore the challenges and triumphs of making a bike fly. Let's dive into the details of the modifications and see this Hoverbike take to the skies!

Install a ring around each propeller so it would control the airflow up and down. Right now the air is going out to the sides. You can see it in the video how the propellers are blowing everything to the sides. With a tube around each propeller you would control the airflow coming from above the bike straight down so it would give you lift at much lower rpm.
but stiil been so heavy, the propellers may not be the right ones and it needs a lot simplicity with a plus carbon fiber elements. I sugest calculate this machine for better results.
That’s the least of the problems. A quad copters propels spin at different rates to keep a level.. of the skirts more than a few feet off the ground that’s going to flip. This is a huge waste of time. Pointless. The Dude must know this and is only doing it for UA-cam viewers. But there will be enough dumb people to believe at all Work and will watch it unironically
Ducting will not solve this problem
@@GordonScottYankeeEngineer But it will help, and it is a good starting point.
@@GordonScottYankeeEngineer Carbon fiber would be ideal but keeping with his metal working background make it out of 1.2 mm aluminum with ribs from same aluminum to give it some strength. By using a motorcycle the hole thing is shot but it is something to keep viewers engaged. Need a much smaller gas tank, much smaller seat and remove everything of off that machine that he can. But like I said I don't think this is truly meant to fly high.
Even if it doesn't end up flying for now, his skills as a Fabricator are MIND BLOWING! I love it XD
your YZF R1 has plenty of engine power. What you need to make your drone take off is either bigger propeller blades or a higher ratio in the gearbox. The engine will take longer to get the propellers up to speed, but in return you will get much more lifting power and at the same time you will get much more control over the drone.
It’s all about love… 😍
Keep up the good work… 👍
Good point!
@@meanwhileinthegarage🔴 What Is Islam?
🔴 Islam is not just another religion.
🔵 It is the same message preached by Moses, Jesus and Abraham.
🔴 Islam literally means ‘submission to God’ and it teaches us to have a direct relationship with God.
🔵 It reminds us that since God created us, no one should be worshipped except God alone.
🔴 It also teaches that God is nothing like a human being or like anything that we can imagine.
🌍 The concept of God is summarized in the Quran as:
📖 { “Say, He is God, the One. God, the Absolute. He does not give birth, nor was He born, and there is nothing like Him.”} (Quran 112:1-4) 📚
🔴 Becoming a Muslim is not turning your back to Jesus.
🔵 Rather it’s going back to the original teachings of Jesus and obeying him.

Are you ready for premiere guys ?
yes please hurry up… 2 months of waiting 🤦🏻♂️🤦🏻♂️🤦🏻♂️
26:13 🥺🥺 .. change the propellers … and add gear ⚙️ or change it it’s very slow.. don’t focus on the weight right now.
Yes, but faster 😅❤
I don't understand why no motorcycle 🏍 or moped 🛵 company has built a trike moped similar to yours (in your previous videos) with a recumbent seating position & lightweight aerodynamic removable weather enclosure. So the 🛵 could be used all year in rain, cold and light snow. Just like a car but get 75+ mpgs using a 300 to 500cc scooter engine & cvt drive train. So it could go 80 to 85mph capable of traveling on USA 55mph hwy & 75- 85mph interstate systems. The aerodynamic enclosure and recumbent seating would make it about 35+% more efficient. Than the upright riding position of a motorcycle where your body is creating major wind drag.
JUST BUILD A 1000CC HELICOPTER. SHIT WILL HAVE CRAZY PERFORMANCE
Great work, even if it didn't fly. Get a smaller engine, make thinner blades, spread them wider apart, and ditch most of the bike. Thrust to weight is the key.
He isn’t taking weight into consideration whatsoever
@@600wheelI agree. However, it's all learning. Learning takes mistakes to gain experience.
@@criticalmass181 I would think something like weight would be obvious to anybody attempting to build something like this
Lessen weight of unnecessary items of bike, larger engine, larger blades. Far far too complicated to try to do adjustable blades for collective. It would be possible to add extra vanes to act as a cyclic control, but leaning in a craft that small will accomplish that. As far as ground effect, when you lift off, you lose ground affect as you ascend. A helicopter does not have the propeller near the ground. They depend on much larger airfoils/vanes and engine HP / speed.
You have to increase lift from propellers and lose weight. You were 360kilos on bike engine/frame before installation. Now maybe double that 700+ kilo. 1,500-1,600 pounds will take much large air movement to lift the craft that with everything added was pushing 900 kilo. 2000 pounds (USA) =909 kilograms.
I really respect your determination.... Remember, the difference between success and failure, is determination..
Отличная идея! Ховербайк явно нужно немного облегчить, такое ощущение, что не хватает совсем немного. И главное - предлагаю поменять передаточное соотношение - поменять звёзды, и, таким образом, поднять обороты на винтах еще сильнее.
Great idea! The hoverbike clearly needs to be lightened a little, it feels like it's missing quite a bit. And most importantly, I suggest changing the gear ratio - changing the stars and thus raising the rpm on the screws even more.

Usar conjuntos de engrenagens nas hélices aumentaria muito a rotaçao delas e diminuiria a do motor da moto.
توجد 2 مشكلة :-
1- عدم وجود دعامة قوية بين الأرضية والسقف.
2- الوزن، لا يمكن لسقف حمل وزن الدراجة وباقي أجزاء الأرضية.
أقترح زيادة عدد الأجنحة أو تقليد فكرة الطائرة المروحية بوجود جناح كبير جداً.
شكراً لإستمرارك بالمحاولة، هذا شيق حقاً، واتمنى أن تنجح.
Can’t wait to see the latest update on your wonderful machine 👍
It was a great try. I'm looking forward to seeing the next update on your flyer. I've been a fan of your channel for a long time and I absolutely love it!
Thanks bro. I really appreciate it.
I agree, you are a very skilled fabricator and engineer. It won't fly because its too heavy. To produce enough force, you would have to have propellers at least 2.5 times the mass of the rig. Even then, you'd only get a few feet off the ground. If you had materials just as strong but at a quarter of the weight could work too. Whether it flies or not, we will all be cheering you on!
Thank you for this prototype that you builded (i had exactly same idea, but no funds). I think it would fly yet, just after small corrections, i would make wider X under the bike, bigger propellers - if 4 couldn't lift, make 6. If you watch carefully center of gravity moved forward (back of the machine want to lift more that front).
Something to consider, although it may have minimal effect here, is the force pushing the assembly down from the airflow moving against the upper grill, your body, the motorcycle, and the drive covers below the bike. If you could reduce this in some manner, it may help. I'm sure having the upper grill between you and the blades is great protection, though. Most drones have the blades in free air with minimal frame material in the air flow. You've probably thought of this already. Really appreciate your effort and craftsmanship.
МашаАллах! Вы какие молодцы, подкованные технически. С уважением из Дагестана
The first one near the ground was good you just needed to put rubber skirt around the bottom to help keep the air from getting away' Then you need propeller behind driver to propel him forward and a way to move the propeller behind him for turning.
A helicopter pilot friend of mine was trying to build a similar vehicle 15 years ago. This design was a mixture of a jet plane and a motorcycle. We made a "mockup" together and he went to a fair in Dubai with the mock-up to find sponsors. But he couldn't find anyone to give 1 million dollars. :D His hoverbike design was just like yours, but his had a small helicopter engine under his seat. Instead of propellers, there were 4 fan outlets, just like on Harrier planes... But when he could not find a sponsor, he wanted to use this "mock-up" in a different way. He built a huge robotic arm powered by hydraulic pistons and mounted that "mockup" on the end of the robotic arm. He also sold this new toy to an amusement park :D
(I will leave the Google drive link of the photos of the design under this comment , I hope the link appears.)
Send him the link via email for him to put into the video description otherwise the link is not accepted by UA-cam. Links here are accepted for another UA-cam videos, that's all.
Waw, looks like a lot of work since the last video. And you are alive and well, that is good 👍😁
ماشاء الله انت مبدع You are creative 👍🇪🇬❤
Bro!! You got this. I feel you’re on the right track.
Мовсур я на испытаниях аж покурить вышел. Мне кажется в ногах пропеллеры безопаснее выглядели. Берегите себя!!!
Спасибо Михаил. Не передать как страшно было)))).
When something goes wrong, it's not a failure, it's a learning experience...congratulations for the idea !
You are really close and I agree you need to drop some mass to fly. If you have access to four load cells then use them in a full power runs to see what the apparent load is at full throttle. That should give you your mass reduction goal, I'd say about 10kg should do it. Try a run with minimum fuel and a muffler deletion.
Directly from Brazil, we followed your saga in this project. I wish you success.
I hesitate to make any comments sitting in a chair and having never built anything as beautiful, brilliant and complex as you have. I have read that power required goes like the cube of the prop tangential velocity, so two big and slower turning contra-rotating propellers might get you more lift for less power. Best of luck.
You're right about the weight, and reducing it down to two rotors is the right idea, but co-axial rotors is very complicated and you'll lose more power to mechanical inefficiencies. What you need is a something like a Chinook helicopter, fore and aft rotors, counter-rotating to counter out torque, and staggered, (aft slightly higher than fore) so the blades can actually over-lap each other. That, and drastically reducing the weight !
Great video, always enjoy your content.
Definitely need a stronger motor, OR to replace some of that steel with aluminium.
Double (2 layer) rotors might work since they can grab more air as they spin.
Another option would be to extend the platform to the front and back, then change where the rotors are positioned (1 pair further to the front, and 1 pair further to the back.) Then put a third set of rotors in line with the middle of the bike.
Давно смотрю Вас, экстремально. Берегите себя! Несущие винты у земли с одной стороны выглядели опаснее, с другой вероятно, создавали большую подъемную силу, в начальный момент поток ближе к земле, ну и валы с крепежом добавили веса. Удачи Вам!
Всем здравствуйте. Как всегда автору большой респект за проделанную работу и конечно же лайк. Очень хочется что б этот проект поднялся в небо, поэтому хочу поделится мыслями. Авиостроение вообще не простая вещь, при создании летательного аппарата всегда много проблем: масса, тяга, устойчивость, управляемость и еще куча всякого...
По этому поводу думаю что в районе руля много бесполезного железа. Выбрать металл из всех не особо несущих плоскостей. Постараться максимально уменьшить массу. Каждый грамм на счету. Все таки может стоить подумать о замене винтов. Продаются же деревянные для парамоторов. Сделаны с хорошей геометрией, да и тяга известна и оптимальные обороты. От этого можно будет оттолкнуться и посчитать массу и задать нужное количество оборотов. Опять же уйдут громоздкие ступицы. Вот такие мысли, удачи и с нетерпением жду продолжения.
Huge fan since you started. I’m a retired mechanical engineer in Kentucky USA. I wondered from the beginning of this build why you didn’t apply twist dynamics on your propellers. They, and I’m a novice in aeronautical engineering, but it’s my understanding that they create more force because the hub spins faster than the outer of each propeller. Ie. more twist, more force., also more stability. Good luck my friend
Huge fan! Pun-tastic...
Tip speed is always faster then the hub speed
Can wait to see the next one, thank you for the video and i appreciate all your hard work.
My favourite engineer/machinist/fabricator on here (sorry Kurtis and Adam 🤷🏻♂️)
Seeing you doing your test flights reminded me of Neil Armstrong doing similar in NASA flying machines. Keep safe and carry on building your wonderful machines.
Increíble las cosas que haces. Excelente trabajo. Te felicito
I believe that you need bigger propellers and that maybe you should change gears so that the bike is not revving so much.
I would love to see this project literally get off the ground.
So good luck and I am waiting with bated breath for the next video.
Kind regards Richard from Dronfield United Kingdom

An amazing job guys! Love watching your videos!
Спасибо за твои работы. у тебя все получится
widen the cadge length and width longer blades but thinnen. go back to the previous design but raise the plat form up off the ground 3 feet. by doing this you will max air flow and have better stability
I think,you are the best because the inspiration to created for something you have do it.
Parabéns
.. seus projetos são sempre muito legais
Transforma em um hovercraft
Yes - no ground effect - but also you cannot take off indoors (that is a bit of a lol moment) the air must leave the bike and have little air resistance past the bike and in flight blow down towards ground and keep going straight - NOT recirculate around a room and come back around the ceiling and press back down on the bike. Last time I sent you a drawing of cowls - the cowls reduce the blade tip losses and increase efficiency of blade dramatically - they need to be about 10mm from static tips for safety. Now that you are a helicopter you need to extend the cowls down to your chain drive level (no more) so your air gets a clean path past the bike and has best speed on exit of cowls . You can also put air flow straighteners in the flow for efficiency and use them as structural members if necessary- I think your steering vanes should be moved also to the exhaust of the cowls - bear in mind the vane distance from the vanes to your centre of gravity is a major input to its efficiency - although you could also try to regulate flow rate but that may be cumbersome. I would still propose the cowls create a modicum of air going backwards as hanging is likely to be more unstable than a little permanent forward motion. Be careful if your flaps have no effect at 10 degrees because then there will be huge instabilités if you go past say 45 degrees (flow changes from laminar to turbulent) si vous préférez le Français - allez-y
Idea's : Carbon fiber engine cradle/cockpit. (You need to be sitting in front of, and level with the engine.) To make carbon fiber panels, just create a square/rectangular form then layer sheets of the C.F. until desired thickness is achieved. Cure the panels then cut out the desired shapes. In other words, I'de abandon the "motorcycle" aspect altogether. (This could also be done with aluminium, etc.) This would not only lower the weight by getting rid of the existing frame but also the weight of the lower chain drive for the rotors as welll. The rotors definitely need to be above the vehicle.
For more lift you could change the gear ratio at the front and rear sprockets in order to create higher rotor speeds at lower rpm, and space the rotors further apart so that you can lengthen them. OR, you could convert the engine into a generator, and run electric motors. If you go electric that eliminates ALL of the rotor drive. It would also allow you to put a cowling around each rotor producing even more lift. You could also run 6 or 8 rotors for even more stability. Forward, reverse and lateral movement coud be achieved by moving the rotors themselves. Two control sticks- one controls F/R the other R/L. I'de be tempted to try using servos, or hydraulic assist for rotor positions. Gonna go fabricate a sandwich now. Have fun, and get it on video. :)
Thanks, keep on ! 👍
Awesome try, now you at least have a whole shop air fan😂😂😂 you are quite an engineer 😊
By raising the props above the rider you have allowed yourself the ability to make bigger props if you raise two of the props in opposite corners. Bigger props would allow them to produce more lift at a lower RPM and the length of the props would be limited by the interference in opposing corners rather than current configuration. Not sure if that will help but just throwing out ideas.

More thoughts:
The chain drives are too complicated. Maybe use the bike engine to drive a generator, and use the electricity to drive motors. That way you could use the controls out of a quadcopter drone to control your bike.
By returning the rotors to the bottom, but angling them by raising the farthest point on each from the center, it would angle the line of thrust to over the center of gravity. By angling all four rotors this way, the lines of thrust would intersect at a point over your head, and directly over the center of gravity, provided you have mounted the bike correctly and taken into account the position of the passenger. This would allow you to still use ground effect without sacrificing stability. Picture the lines of thrust running through the axis of each rotor. Now tilt the rotors until those lines form the edges the edges of a pyramid. Now picture someone sitting inside that pyramid with the top of the pyramid just over their head. The top vertex of that pyramid would be the new center of thrust, which would be above the center of gravity.
Propellers may not be the answer. Have you considered ducted fans? The key is generating more lift than the device weighs. Ducted fans are much more efficient.
If you use the idea of a quadcopter drone control setup, an engine driven generator, and four motor driven ducted fans, you don’t need the motorcycle body, which is very heavy. Mount the motor/generator directly to the platform and fabricate a lightweight seat. I was thinking a lawnchair with a HOTAS joystick and throttle setup. The Warthog gamers HOTAS comes to mind. It has two throttle levers ( which can be used for speed and altitude) and a joystick for direction. At in some rudder pedals for rotation and you have full control. Of course integrating these controls could get interesting. The HOTAS and rudder pedals think they are talking to a PC, the quadcopter controls think they are getting inputs from an RC controller, and that they are talking to a toy drone, not industrial size motors. It would be interesting to see if you could get it working.

Love u brother i am happy for you great work whenever i am depressed i use to see your videos again again and get motivated jazakAllah khairan kasreea
Ameen. JazakaLLahu hayran ya Ahi
Зробіть гвинти трохи більшими, дякую за відео, як завжди класний контент.
According to my calculations, you need a minimum of 300 hp, and about 300 lbs lighter. So a small gas turbine engine from a small helicopter should work perfectly.
The fanes size is small according to weigh.we encourage your work.God you give success.
I thinkthe biggest issue is the propeller shape/cross-section, like another commenter said.
See if you can find 4 proper aircraft propellers - like from a paraglider. The efficiency of your homemade blades is just too low. Also remember that the tip speed should be close to but below the speed of sound (360m/s) or the efficiency will drop sharply.
Set it up remote control and see if it lifts without you on it , To give you an idea how much weight you need to reduce .. You do awesome work don't give up on it , Cheers.
Дружище! Главное не сдавайся! Всё получится! В следующей части обязательно полетишь!
Dude you are AWESOME... I love watching everything you do... but yeah, I also think that's too much weight and for this configuration, I think the propellers should be bigger... you need more air moving so you can lift-off...
Дуже гарно,КЛАСНА ІДЕЯ
Changing the design to a ducted fan system will help a lot, now I'm no engineer, but those blades look a bit heavy as well, I know they're expensive, but fan blades designs and materials can make a really big difference.
Los felicito muy bueno con elises más grandes vuela por qué vuela y muy lejos seguro qué dios los bendiga siempre
Цхьа К1ант вукх хьо !
Цхьа к1ант вукх хьо. Вот так будет правильно, main Freund.
Hell yah man, ive been dreaming of doing this for years, let me live vicariously through you! 😂
I have to let you know, it doesnt actually change anything to change where the props are. I think they called it the rocket pendulum effect, or something along those lines... Its like moving the battery location on a rc quadcopter, makes no (or nearly no) functional difference.
Its gonna need you to increase the speed of the rotors, or the number of props... Id suggest simply adding a second rotor set below on the same axle, that way you nearly double the thrust (and of course the amount of torque needed, but i dont think youre anywhere near maxing out that engine.) For a quadcopter to fly comfortably you need minimum 2-3 times the weight in thrust, more is better, but you also need very high levels of torque for spinup/spindown to control angle which there are a few ways to achieve . Youll get it man, i believe in you
😊
МашаАллах1, Дал т1аьхье беркате йойла👍👍

Ahora está más equilibrado, solo falta aligerar materiales y mejorar la transmisión de velocidad hacia las hélices. Sigue adelante amigo. Ya casi lo logras !!!
maybe put the some circles around the fane. that may help the air to go down directly into the ground.
that looks like it's balanced better and safer.
I dare to say: less weight, and largest propellers!...but I am a doctor not an engineer☺...@2010invent idea seems to be very interesting too. Anyway, you're a fantastic mad constructor and I' m always waiting for your videos...go one this way as far as you can!!!
I agree, too much weight. Could cut a lot of circles out of the frame to lighten it up. Get rid of any excess weight on the bike. Efficiency may be a little low with all the complex linkages to the props. At any rate please take extra precautions. Don't push the envelope too far and stay safe.
Попробуй по два пропеллера на каждую ось, как вариант 👍
You are crazy man) Amazing work!!!
Barkal
Well, I igree. Too much weight for less power and wings as such its needs.
I believe mechanical loses in the chains and in the central reduction from the K bike get the result worst too.
Whatever, a think it become easier make this machine to fly if it looks like a airplane, not a drone.
Let the engine provide the power to a mobile blade, while the bike had solid wings.
Incredible idea, amazing skils for this craft work, good luck!
Just had a thought, if you used a harley with extended forks, you would have a real chopper😂😂😂
For real though, to me(and im no engineer) it seems that you need to have your propeller force directed more down that out/down. So maybe a shrouded prop enclosure? Also, at the rpms you are having to reach just for lift off, thi build seems unsustainable with the eventual motor destruction. To me(again, not an engineer here) you need a motor that has the ability to reach the high rpms needed with MORE torque. A motor that had more torque would allow you to shift to a higher gear ratio thus allowing faster propeller rotation.
This is good work and i would love nothing more than for this build to succeed. I can hardly wait till y'all dial this in and get it working. Keep up thw great work.
Good Effort Bro
Best Wishes from India 🇮🇳 Karnataka
Dit is helemaal geweldig 🎉🎉🎉❤
So close to taking off I wish you had a video every week, better luck next time 👍👍
I will try my best
Аллах1а аьтто бойла хьан!
Good try.. we loved your work.. you are brilliant creater
Молодец. Дал аьттув боакхалба хьа.
على ما أعتقد أن الوزن كبير بالنسبة إلى المراوح الله أعلم.
على أيت حال مشروع جد رائع، شكرا.
Awesome build. I was wondering if adding some small gyros on it to alter the center of gravity would have helped. Glad to see you back at it.
Ты вообще молодец!!! Идея просто прекрасна!!! Круто!!! Просто мощности не хватает. Я сразу понимал что не взлетит, и сразу понимал что ты зря новый мотоцикл купил. Тут нужен автомобильный двигатель 70-80 лошадиных сил, а не мотоциклетный 15-20 лошадиных сил. Ну то есть в 4 раза мощнее нужен двигатель чем тот, на котором ты пытался взлететь. ПРОДОЛЖАЙ!!! НЕ ОСТАНАВЛИВАЙСЯ!!! ВСЕ ЖДУТ ПРОДОЛЖЕНИЯ!!!
You can make it my friend please keep do it. I do like.😊😊😊
Bigger tinier blades spread apart further more, reduce the weight. Good luck.🤘
I wonder if the fans were ducted a difference would have been made. Great attempt guys ,
Good effort, but you said it yourself, it's tway too heavy for the thrust developed to overcome its overall mass. Suggest you take out the engine and redesign a much lighter frame, you need half the weight of the one, you have now. That should lift off the ground, but controlling it in the air, is another matter. Well done!
Version 2.0 makes much more sense, but V1.0 looked bad-ass!
The process of making a Hoverbike is solid, this really requires a lot of effort, I pray that it will be successful quickly
Hard work you put in it but motorcycle is not made to fly very havey if did two rotors with counter rotation with light aircraft you will be flying, use aircraft design will help you to build one.
You got to have more thrust so add more propellers. I think you have a plenty of power. Two propellers for each shaft. Good luck
i think you are on the right track with the dual rotor design in the middle. This is a long shot, but why not make the engine drive a very powerful three phase alternator, and use a big brushless motor as your drive for the rotor. I think this can be very expensive and i dont want to see you go bankrupt my friend... But you would have the engine at a constant rpm and could still modify the speed of the rotor with a ESC.
Muito legal seu projeto!!!!
Espero que dê certo!!
You should add covers for the propellers - In case of hitting, accident or falling - The propeller will break free, and shoot like bullet - Make it safe for yourself and others
однозначно нужна переделка редуктора-двигатель впустую работает на максимальных оборотах,на которых винты не выдают необходимую тягу,а должно быть-двигатель уже на 1/3 от максимальных оборотов должен выдавать тягу на винтах,достаточную для отрыва от земли-нужно увеличивать число оборотов винтов.Или ещё вариант-увеличивать размер лопастей винтов без увеличения оборотов,но тогда увеличится общий размер ховербайка.
Но на мой взгляд-лучше версия гибрид-основа-это электрический квадракоптер-винты вращаются электромоторами и управление идёт как на обычных маленьких квадракоптерах-стиками.А питание электромоторов-от небольших аккумуляторных батарей,подзаряжаемых от электрического генератора(который вращает мотоциклетный мотор,работающий на постоянных оборотах).Это даёт более гибкое и стабильное управление полётом.А всю ненужную мотоциклетную механику и тяги к рулям поворота(вместе с рулями поворотов)-это всё выкинуть как неэффективное.
Посмотрите конструкцию агродронов-там именно такое построение аппаратов для длительной работы-дополнительный генератор на ДВС.
Meanwhile in the Garage ? from the looks of it, your RPM on the motorcycle are maxed out. try these steps below.
1. find out how many RPMs do you need to create lift.
2. find out how many RPMs do you need to lift the whole weight of your craft.
3. find out if your motor is to heavy and if you need a lighter one.
4. find out the maximum RPMs your blades can handle.
I would check RPM of current setup then try propellers with different pitch, blade number, curviture on a thrust scale. Electric motor to measure pounds of lift for each change. Ultralight planes are very sensitive to every tiny detail of those blades.
По звуку мотор ревел на максималке или близко к тому, то есть запас по моменту присутствует, значит нужно увеличивать размер пропеллеров (не шаг, а дюймы). Также для управления и стабилизации горизонта, применение направляющих поток плоскостей - не лучшее решение. Лучше перейти к классике, более сложной но более эффективной - регулирование тяги винтов, применить 4 механизма изменения шага на каждом пропеллере управляемые сервомашинками на соответствующий момент, и тогда можно использовать стандартный полетный контроллер для мультиротора.
Удачи ребята! Вы одни из тех не многих, которые пытаются построить рабочий мультиротор с одним ДВС.
Спасибо за объективную оценку, и советы!
Hiller Platform=stabil & effective !
140 HP, D=1,6 m
Bigger diameter and lower RPM props (with smaller attack angle) - are more efficient in terms of power/thrust ratio. Big two-blade rotors are more efficient than 4-blade rotors. But they have bigger diameter. 3-blade rotors more efficient than 4-blade rotors ets.
This thing is epic! Even if it doesn't fly
