I would like to share a recent project that I found on the internet, such a nice design these guys made with carbon fiber body.  I wonder if they are using pixhawk 2.1? lol

It looks so light flying!

Does it seem to be a combo design using a vtol vehicle with helium inside?l What do you guys think?

No helium, just 8 powerful motors and a nicely designed flight control system. Also only 25 mins on a battery of about 28KW/h.

I know several people I would like to buy tickets for rides....none that I care about

I think we are watching a time-distorted video. All of the video clips appear to me to be slowed down to leave the impression of ultra-smooth flight and landing. If we could be sure that the video is being shown at an accurate speed, this truly is an delightful concept. If the video speed distorts our perceptions, then I have concerns.

It looks so light flying ... because it is a computer animation.

This is a combo design using a vtol vehicle with helium inside:

HI Arnaldo, that looks very cool, thanks for sharing - it is a manned aircraft though, not a UAV - unmanned aerial vehicle.

It's a 8kWh battery in the US spec, 12kWh international. I don't think the footage of a prop hang is time distorted; there is at least one shot of a full speed takeoff roll, shot from overhead, with the Blackfly on a grass hill. The specs state 3' takeoff and 3' landing runs, so it is really more of an extremely short take off than truly vertical, but in reality it is close enough. This probably indicates it uses ground effect for initial take off, before being able to switch into a vertical prop hang mode, and it would be interesting to know more about this transition area. You can see that some of the shots have a dummy in the cockpit, but it is interesting to note that all this footage is of the v3 design, not the current v4 model.

Somehow this is rated as an ultralight, which is categorically up to 254lbs in the US, yet the Blackfly weighs 313lbs.  Equally impressive is the 72dba noise rating.
