Submission attempt #2.
Ahrrhm. After finally getting back on track with it I've managed to 75% finish the model.
just need a texture for the fusilage a cockpit and a working set o landing gears

Looking good so far. This has progressed a lot since the last model i saw.
The overall structure looks very well thought out and leaves much to the imagination, especially with the appearance of being a functional aircraft. However, if I recall correctly, the original design called for a VTOL engine design. In their current layout, the engines would function well to point down for takeoff and aft for propulsion but may have a difficult time rotating through a forward position or even upwards. I recorded my thoughts on a possible mounting method for the fans with illustrations. They can be found here: http://www.furaffinity.net/view/1058973/
Considering the design is reminiscient to that of a jet (and the fact that the vertical stabilizers are quite small), the design might benefit from an upturn on the wingtips. This would allow for a little more stability and increase the aircraft's resistance to yaw. An example would be the wingtips of a 747.

Not necessarily a wingtip-based rudder so much as a vertical stabilizer alone. Making them a combination would be ideal for control purposes, but would expose the rudder controls at the ends of the wings. Also, if one rudder control were lost, the majority of the yaw control on the plan would also be lost.
Compare it to that of a stick you hold in an open hand. Balance the stick on your palm and rotate it. The strick will turn quite freely. Now, hold the stick at the end and try to rotate it - i think you'll find it's much more difficult to get a low-diameter turn than if the stick were balanced in your palm.
The rudders on the engines will allow for a good deal of yaw control, however at speed I think the design would benefit from the addition of a more traditional style rudder near the centre-rear of the aircraft.

Hmmmm, I have studied your design through finding it through 
harlanj's submission. In his submission you have stated that the engines would work like a jet engine. Where is the huge other half of the turbine that would compress the air (to provide the heat required for combustion) to then be mixed with the fuel? As it stands the engines would not produce enough power for flight. The turbine itself, is, in a way, self-perpetuating, as long as fuel is constantly being supplied to it (given the high pressures for combustion are being provided by its compression turbine). To initiate the equalibrium however a large starter motor would need to be including to bring the turbine up to speed required for initial compression. If i am wrong in understanding the engines' mechanics I do apologise, but tiger is confused somewhat. The size of the turbines seem to small to develope the power required.

actually to be 100% about it, the engines are neither jets nor cylinder combustion.
it's really kind of a turbine cross rocket motor that uses a pre-formulated mixture of fuel and oxidant (stored seporately for safety) which ignites in the engine and propels the internal turbine which then drives the fans.

ha... as a model, it's well out of reach for the average enthusiast to play with since it's almost 67mb in size.
But.. if I can simplyfy the design, and buy some sculping parts. I might be able to make it IRL.
gonna be like putting together a model galleon without an instruction manual.

a small scale would very likely work, considering that air is a whole lot denser when things are scaled down.
Tear up two peko mini helis for the engines, and fashion some kind of custom remote and the thing should at least get off the ground.... flying is another thing. Gonna have to fine tune the thing's aerodynamics before that.

The fans are direct driven from a motor mounted on their housing. My understanding is the motors utilize a rocket-based design, possibly with modified turbine internal components. About mounting a larger turbine in the fuselage, could you elaborate a bit on this? I'm having trouble understanding why you would duct the exhaust gases out onto the fans rather than driving them directly.
Regarding low-speed flight, the aircraft would have good maneuverability in normal flight, but at low speeds would become unstable. This is due to the length of the nose and the placement of the engines in respect to the centre of gravity. Considering the style of engine employed here in the fans (which I am having trouble comprehending as of yet, I need to think about it more), a separate engine could be installed in the fuselage toward the nose. This engine would employ a fan setup similar to the F-35 and point downward. It would only engage when the airspeed dropped below a certain level or when the operator predicted instability in the aircraft (during landing, maneuvers, etc). This would, however, add another level of complexity to the aircraft and allow for one more major component failure.

This is an incredibly intricate piece of work. Incidentally If your looking for design thought, go to a good air show. Find the Harier jet and feel her up. They usually are not roped off and you can find her little jet holes all over her body. Stick your head up one of her pipes, and there is one Rolls Royce engine right in the center. Very cute.
