We succeeded 2015/06/25 with a test flight (craft strapped with 4 ropes) with a 80 kg payload. It only used 8 of the 12 rotors! Next,we want to give you a glimpse on how it will look in future (part with canopy) Hope you enjoy. And for all the critics: you helped us to pursue our targets! And indeed a lot of challenges ahead, range extender, silent props, etc.  Any suggestions welcome.  We are now in the stage of seed capital funding. Also there suggestions are welcome.

Dear All

we have moved to a new website www.one-man-drone.com. It gives an idea on how the system will look!

After testing of motors and props and the carbon fiber tubes, we are currently building the craft. We have done quite some R&D to take all the steps in designing and received lots of comments. Thanks for that!

Will keep you updated when we move in a few weeks to the tests. Will start without fuselage and use sand bags, don't worry!! We have done quite some R&D on the technical part, the market, certification, and RPAS applications firefighting, agriculture. We see it can become professional after the demo. Any suggestions welcome!

Best Regards, Winfried

Dear All,

As we are now have finished the belt drive design as you can see, we are now in the making of it. Once we have tested one unit we can see how it functions, (acceleration, control, stress, vibrations, etc..). But yes always there is to be

a plan B. And good to advance in that direction too. That craft would be configured just like the original see earlier blog. But at each end iso one e motor with belt, there would be two motors:  one up one down (just like in some quadrocopters). This would be a compact alternative with more redundancy. 

The motors would be controlled separately and we can vary the top and bottom speed. 

We see at first investigation that contra rotating props can have some higher efficiency as 2 seperate ones. We also understand that the prop pitch of the lower prop needs to be higher as the down wind it receives from the top one can then better be used.  

Now the issue is: does any one of you have experience or rules of thumb or simple first effect formulas to tackle the issue? Would think that with the some of the drones this issue must have been studied?

Hope to hear, Best Regards, Winfried team www.TheHummingManProject.com

Due to the safety aspects of the man drone we "invented" a combination of airbag and parachute with the purpose of opening the parachute in a spit second. We made a small testing sample. and we think it can work. So the idea is that a drone in an emergency situation would ignite a rocket parachute and that this one would open by airbag at the the top. Think that for normal drones (_tumble bee_ ) this might also be interesting. Anyone interested in such development, or sees a need for such parachute that should substantially reduce the the rescue height?

Best Winfried

PS in the blog of my www.thehummingmanproject.com I have a small document for download.
