Introducing AIrVator.

I would like to show you guys my most recent work on conceptual design of a manned drone.


After designing many different kind of mini or micro sized drones myself, I begin to think about making a huge drone as others may already started to make. 

I think 200kg payload should be a must for the drone later however, VTOL or anything hybrid system are only making drone more complex and hard to maintain. So quadrotor best fit to KISS (Keep It Simple, Stupid) for any industrial and transportation purpose. 

This design is based on 280mm wheel base and about 1/20 or 1/25 size of actual manned drone.

If someone find this project cool and want to participate, please give me a message or send an email to

    I think the design of volocopter was due to limited power of motors at the time of initial development and now they are thinking about reducing number of motors. Because running many motor is inefficient, complex thus making the copter less capable. 

    Now there are many big, powerful, efficient motor that is enough to hold more than 100kg per motor and systems are getting more stable and reliable. 

    I strongly believe there is way to make this system safe and that is the way we should achieve.

    Thanks for your comment. Have you ever wonder how much costs are associated with helicopter? Maintenance, pilot training, so on.. I think any conventional aircraft can beat overall cost, easy of handling and etc of multi rotor type aircraft. I don't say multi-rotor aircraft is better in payload, endurance. The true competitiveness comes from its simplicity in terms of mechanical, electrical, and systems. 

    There are already many devices including parachute as you already mentioned, to provide safety measures for multi rotor aircraft. 

    The point is however, converting multi-rotor into VTOL by adding complex wing, actuators, ailerons, control logic is only making simple solution worse. 

  • Apart from anything else the others have warned you about , nobody , surely, would risk their life in a 4 rotor craft. A failure of any part of the drive line on a single corner will see the craft fall out of the air.

    Volocopter is the way to go.

  • Apparently Dubai decided to go with Volocopter and signed them to a five year trial, not sure if Ehang is getting the same. 


  • Why do so many people want manned multirotors? This is the last thing I would ever want to get in. If there was ever an issue, there is no way to safely get to the ground short of a parachute. Not to mention its extremely inefficient compared with traditional Helictopers.

    I am waiting to see some cool designs for Electric Single rotor helicopters, but, what is this fascination with manned multirotors? They are Dangerous, Less efficient, and completely reliant on a stabilization device.

  • Hi Xrotors,

    Won't work, fixed pitch props do not scale to use for hovering vehicle as you are showing.

    It's that simple a fixed pitch manned quadcopter cannot respond quickly enough for either maneuvering or for gust and wind conditions.

    More props (lots more props) can counter this situation, but the most practical fix is variable / controllable pitch props.

    This is a simple well known matter of physics and air density and mass and is a perfect example of trying to scale something in a fixed physics envelope and getting outside that envelope.

    The motors / props on the bottom is a good idea , because reduction in efficiency caused by support strut air interference is noticeably less than strut under method.

    Mesh causes a lot of interference and loss of efficiency a surrounding bumper / hoop at prop level can work, but many attempts at using mesh protection have been tried and abandoned.

    I would greatly suggest you spend some time on Google researching this, not all things scale straightforwardly and this is hugely one of them.

    Thanks for your comment! Prop facing downward while arm on top make clear thrust from the prop and I designed it is high enough not to harm people. Also they will eventually be covered with some kind of mesh to keep clearance to anything near. 

  • Nice! Why do you have the motor and prop below the arms and not above the arms?
