Check this one out.

Came from the Concept ships blog site, Very cool

Brilliant, I love the concept!

(But it has no tail rotor, and thus is just a multi-ton paint-mixer.)

Wow ! That thing is awesome !

Bah!  Tony you obviously missed that it has a counter-rotating setup and the pic shows both sets of blades at the precise moment when they are perfectly aligned!   

OK.  That is a serious beast.  Four engines?  Man that thing could lift a Abrams!

Is there a side view of it sisko?  There seems to be something missing, for example, you can see four dust filters but only two engines, we should be able to see the long engine nacelles behind the top two in this view too.

Maybe it has a NOTAR system? Would have to be a really powerful one though...

Aesthetically impressive but, from this engineer's point of view, not all that feasible as you structure is going to be a whole lot heavier than a standard CH-53E.  I think he narrowe or truncated the aft fuselage such that you really can't see the rear two engines (looks like he mirrored the third engine to add a fourth).  'Twould be interesting to see afour-engined Super Stallion, at least as a experimental aircraft.

Looking at my model of the CH-53E the third engine is on the centerline behind the rotor mast, there wouldn't be room for two engines there, at least side-by-side.  If a four engined CH-53 was made I think it would have to have two extra podded engines like the front ones, it's something I've been thinking about doing myself.  I tried it with my EH-101 AEW project but the two sides of the rotor pylon are completely different so gave up on it and stayed with the three engines but made them bigger, but the CH-53 seems to be symetrical and if I build mine I think I'll splay the rear ends of the front ones out a bit and then fit the other two behind them splayed the same way.

Very Gerry Anderson 

[Stargazer]

Very impressive! But the problem is 1°) probably very heavy... 2°) unless there are counter-rotating rotors it can't work... 3°) the rotors would have to be raised so the blades don't hit the pi-shaped tail... Therefore the gain of such a configuration (other than the fact it looks GREAT) is questionable...

Why is everyone being a JMN over this picture, its a cool pic.

HEY!! I put a smiley on my post..... lighten up Francis!

Sorry Aircav, didn't mean to come over like that, it just seemed to me something was missing and I wanted to see a side view to see what was done.

For helicopter what-ifs, the Helistat is, I think, the most special of them all.

Beyond that of a heavy lifter, what other role can it (or its successors) take?

Re the CH-53 twin-tail, I admit there's no evidence of it in the picture, but one solution might be that it has two fenestrons in the tail fins.
