More like a flying weeble, no wheels.

"I bet it sounds like a chainsaw"

The literature says it is "all-electric". The pilots are not wearing heavy duty ear protection in the video. I submit that It probably sounds more like a large flock of hummingbirds.

Is it just me or did some of the shots look CGI?

Not just you. Also looks like a prototype being lifted by a crane in some shots. The propellers look too small to lift that mass.
I was also suspicious that they had so much footage under various lighting conditions. The twilight shots especially, which are dangerous conditions to fly under. Could be we're wrong, and just be artful CG for the sake of a fundraising video?

If there is one thing I have learned from cinematography, NEVER believe the lighting condition! it is insane how many night scenes are shot in the day and color corrected to night in the final.

I think the cgi-ness is our brains trying to associate what we see with what we have seen in the past. This vehical seems to be;

a) Super light weight hollow body
b) DC motor driven
c) all electric

It is literally a big boy version of modern RC helicopters which also exhibit weird looking physics because the motor totally overpowers the mass of the body.

Obviously most of the footage is of the only way this vehicle can hover, on its back. Being all electric and light, the flight time is likely only minutes.

We have seen many vehicles like this, the only puzzle piece no one is solving is a sustained source of power.

Went to their website and didn't find anything about how much it would cost.
