Who has not dreamed of being able to take off vertically on the spot? Levitation is fantasy -- or high technology: Carried by a compact, efficient machine... Thanks to modern electric motors and lightweight power sources, this is possible. How? -- I would like to show you my homemade person-lifting 25-kg-craft LEVTER in this video.
Yes, I'm still alive. I'm going to sell the project in the present condition to anyone who is more courageous, so to say.
How much are you asking? Also what are the brand, model of the motors and propellers?
Indeed , Franz Schofmann was a genius which I had the fortune of meeting in Wels.
You did a wonderfull job !!
Schofmann had a very good reason to use the co-axial system where minimal difference in lift between the two rotors only affected the altitude.
Slight difference in lift between the two rotors in your system will cause a balance problem.
Consider changing your concept to the Schofmann concept and you'll fly in no time.
Again , well done !!
Thank you!
Yes, that's true. I also talked to Franz Schöfmann on the phone in May 2021. He encouraged me to improve the sensitivity and characteristics of the controls to maybe overcome that.
This has been my dream for so long. Please post more.
I've been looking up small electric personal helicopters for a while and yours is really promising. You might want to add software thrust vectoring like the one Tom Stanton did.
Make yourself a Schofmann tripod frame and mount the Lyvter tube on it , it's a very simple job to do.
If you need any help give me a sign and I'll see what I can do for you.
Again , nice work and you're more than half way cause you already have proven that you have enough lift !!
I guess what you want is is variable pitch propellers controlled independently, but then the machine starts getting complex and heavy and the simplicity is lost, Schoffman went electric on his last machine.
C est aussi un très bon rythme .... pour cette belle chanson.....
Very nice! I hope you are still working on it!
you need a canti-Lever setup like a paraglider, and you can use a pixhawk4 to compensate, Thats whats used in the Jetson and the Vcopter
Es muy bueno el intento solo creo que no tienes posibilidad de controlar el vuelo te falto poder controlar la dirección del los rotores pero esta increible
Oh, I guess you don't have to be able to tilt the rotors individually. It's like Franz Schofmann's coaxial aircraft. You steer through a combination of weight shifting and tilting of the beam on which the motors sit. However, currently I'm not brave enough to try... ;-)
I will be your test pilot. I volunteer and will sign a waiver.
Good to hear! But that might be a matter of logistics. Where do you live?
Well done for building this, great achievement. Have you used a flight controller? Tom Stanton built an rc bicopter same fixed pitch principle and it flew quite well in the end.
Thank you! I don't use a flight controller, it's only controlled by tilting forward and backwards, as well as weight shift and manual differential rpm control for sideward movements and yaw.
What are your thoughts on the stability without electronic assistance? The bicopter configuration should be more efficient than the coaxial design of Franz schoffman but stability might be the issue. Have you done more testing ? I'm at the same stage with a coaxial helicopter and I'm teaching myself to fly it at the moment.
Yes, roll stability is likely an issue. To be honest, with regard to further testing, I look out for someone who is already more experiencened with such kind of machines and flight tests - just like Franz Schofmann, because I'm a bit too cautious.
Well it's understandable that your cautious. It's a daunting thing to be playing with. Hope you find a way to move forward with it.
Wicked !!! You'll get keep trying
AT LEAST
I WANT TO BUY
THAT ONE
Which one? You mean my craft?
Update?
I would really like to see this project succeed, but given the inherent danger, a year without new videos is worrying.
It is in the same condition as shown in the video. I would sell the whole project if there is somebody daring enough who wants to push it forward.
@@vNeumann84 Well, the important thing is that you are still in one piece.
@@vNeumann84how much?
@@benjaminrandle2170 Hi, I would sell the whole project for 10 k$. Condition is as in the video, last scenes. Write me. -- b l u . s k y [ a t ) g m x . d e
Hi.
Can you tell us the max rotation of the motor?
Hi, it has 2100 RPM at max speed, depending on the load. In my test, with props installed it was below 2000 at all times.
@@vNeumann84
Thank you.
I want to build one but I don't know how to calculate the hours power, RPM , weight and propeller size and pitch.
@@adjustablewrenchdiy5907 You can write me an email. The address is in the clip.
@@vNeumann84 ok.
Thank you
what motors did you used? :)
I use two HPD12 by Geiger Engineering.
For some reason to this day I have yet to find a smart safe and simple personal helicopter one can purchase or build cost effectively. And by smart I don't mean one with a computer chip to assist stability or with special control algorithms. There is so much wrong going on in this heli of this viddeo that is counter acting the control instead of assisting. This is the result of builds when you do not know anything about aerodynamics or mechanics. Bi-copter even with assist computers are far less effective and safe in a full man carrying form, than a simple counter-rotating weight shift control helicopter.
Hello,What is the power of each motor.
Hi, each motor has a power of 10 kW. That's enough for >600 N thrust on each side.
Are you in Germany? I would come and fly it.
Yes, you can write me an email. The address is in the clip.
Want to build a structurally counter balanced high speed EDF vtol with me? Imagine the pilot sits in front of this EDF, mechanically balanced - ruclips.net/video/e-25Y7lKBgo/видео.html
