Update of the man drone project

dear Hans, Quite fun that you take the same analogue thinking: indeed the Sikorsky price contender that may be a 1 kW available, And we all know the relation lower differential airspeed makes more efficiency. Our compact design indeed needs some more power ca 6 x 6.5 kW. best Winfried More compact again would require more!

Nice Tommy, it is quite similar to the kick starter project or is it that one?

Best Winfried Are you still in this area?

Of course Tobias we know the evolo and the guy starting it. The size of that one is a little too big in our view; we would like to get it to 2.5 by 4 meters. But indeed we used their lessons.. best Winfried

Agreed.

This community is for sharing and supporting our fellow hobbyists...it's sad how quick the haters pop up everywhere these days.

Sorry to spoil the fun. These people already advanced their human multicopter quite lot: http://www.e-volo.com/

Looking at Hobbykings contest to lift beer, several managed to lift 50kg+. With more engines it should not be a problem. Doing this "effective" is a completely different thing.

My own little drone needs 130Watt for lifting 1kg with 4x 10" propellers.
It's pretty good with 7gram per Watt.

Atlas Human-Powered Helicopter - AHS Sikorsky Prize, where a pro cyclist generate 650Watt to lift 80kg + 4x 20,2m propellers.
Total incredible with 125grams per Watt

BTW, have you test with a scale model? Having a heavy keel under a drone is not always a good idea. It may be better to carry the pilot hanging in a joint coupling.
