Has anyone considered the possiablity of sweeping the main wings more to reduce drag. I know that with this the twist would have to be increased in order to not stall tips first. Maybe im being crazy here. One possibality with too much money and time the possibality of movable wings, so it could remain the same landing and low speed flight. If the wings were swept back far enough it could almost be a delta style wing. I know some very different principials, but it could help with the mach number problem, I was told that a greater swept wing with the same airfoil has a higher mach # usage, Though not from the most relaible sorce.I think that the cannard would have to be different as well to stop it from being the limiting factor. I think this will get really complex really quickly but, Just a thought. Thank You all for being so helpful as well all the great advice in this thread.
