Interesting, but the name is misleading.

http://en.wikipedia.org/wiki/X-13_Vertijet I think this falls under the 'nothing new under the sun'. I remember something similar that was done many years ago. http://en.wikipedia.org/wiki/VTOL Here is one that is very similar but with counter-rotating propellers. http://upload.wikimedia.org/wikipedia/commons/thumb/3/31/Lockheed_XFV-1_on_ground_bw.jpg/220px-Lockheed_XFV-1_on_ground_bw.jpg

We seem to have the technology today to be able to develop and copy the way our feather friends do, which is a control stall when they come in to land. Why not go in that direction, as it will use less fuel.

The new part is the computer flying it and the landing station which isn't a bad idea although it is the only place this thing can land so what is the advantage of this? But saying it could land in gusty conditions with those wings on it is just a dream.

You guys are amazing both the Pogo and the Vertijet were total failures.
Also this little craft flies a completely different mission being small and not having an on board pilot.
I remember back in the days of the Pogo and the Vertijet one of the most common comments about either craft was that the vertical tail first landing was "terrifying"....quite a comment coming from hardened test pilots.
It seems to me that no matter what Gizmag puts up here there are a bunch of people that range in knowledge from zero to "too smart for you guys" that just want to tear the article apart. If Gizmag is so awful why do you continue to watch it? Is it so you can show us how smart you aren't?

Not bad. They should have used 2 6' props with electric motors both lift more and better high speed profile.
By doubling the prop swept area you get almost 2x's the lift/hp. Plus in crosswinds the props counter rotating to each other makes it a lot more managable as much of the torques, wind loads of crosswinds cancel out.
Another is props on the wingtips cut wing endplate drag if the prop comes up on the outside where the prop conteracts the tip vortex.
I found this out designing a WIGE and a seaplane I hope to build soon.

Here is something to weigh: Which is easier - to get under a 100 pound set of barbells and push up - or to put it on the floor and roll it? The amount of energy wasted on vertical lift is not worth the waste.
