Well said, Ollie...

This isn't snickering that's going on here, just rational criticism of a design concept that may or may not be sound. In modeling, design for novelty's sake is an acceptable motive - just realize that the airplane emphasizing novelty may suffer in mission capability. However, the mission may be novelty! Remember, there's nothing quite like showing up at the field with something *really* wierd and fun.

FSW is probably no problem for this plane - the modest amount of sweep extant in your drawings is not going to cause structural or stability problems. A bit of anhedral won't be too bad, either, as long as the wing is above the fuselage, and you're willing to stay on the ailerons allthe time. The one concern I have is the boom structures and the possible aeroelasticity that they may cause. If you use the surfaces on the horizontal stabs as elevons, you run the risk of experiencing aileron reversal, and elevator response may be more than you expect. If we think about what's going on on the wing-boom ineteraction, this may be clearer. for the wing that you want to go down, you'd deflect the elevon up. However, this long moment arm about the attachement point (wing) may cause the wing to flex tosionally - to a higher angle of attack! (uh-oh) Now it wants to go up. Which influence wins out will depend on the torsional rigidity of your wings and the speed at which the aircraft is flying. As I inderstand it, the 777 actually experiences aileron reversal inside its normal flight envelope (at high speeds, of course), and the flight control system knows how to compensate. Unfortunately, the only flight control system we have on models is the guy behind the sticks, and we're notoriously bad at dealing with aileron reversals.

To prevent this, you're going to need to make sure that the wing is very torsionally stiff. This probably means fully sheeted, as wings get much more rigid in this axis when you "close the section" with sheeting. Also, the tailbooms need to be quite stiff to avoid elevator reversal from a similar phenomenon., but this time the stiffness needs to be be in bending.

Good luck with it, and keep dreamin'. Just remember that there is a good reason that most airplanes have a wing up front, a tail in back, and a tube in between.
