OT- Weird RC flying machines

They've been advertising these two oddities on TV.
Hard to know what to call this... it goes around on grass, sand, snow,
water...then it takes off and flies around like a "Flying Flapjack"
fighter plane:

I don't fully understand how this works... is it so light it uses body
lift? Something involving prop wash over the midget wings between the
floats? It appears to take off via wing-in-ground-effect. Whatever it
does, it would be fun to see one scaled up to human carrying proportions.
The other one gives me evil ideas....a tiny helicopter around the size
of a sparrow, controlled by RC in six directions, and designed so that
it can be flown indoors: http://www.youtube.com/watch?v=7Wf2zoqanEY
See? It's flying over the bed.
You could conceal it in an ornate headboard for the bed, wait till the
Atreides heir is asleep, and have it fly out and stick a little needle
full of cyanide into him.
And that would be okay under the Laws Of Kanly.
You wouldn't even need a reason.
In the words of Jean-Paul Sartre, 'Au revoir, Muad-Dib'. :-)
