Bat1, i was just wondering about "ping"ing this thread again...
I suspect that having generated much good publicity on the potential for high speed helicopters X2 has been handed back to the engineering development team for the various ground/tethered test activities which precede a test flight. Machines are now just too complicated for the jump in and see what happens approach of the past. It will probably undergo some strain guage durability proofing to demonstrate that everything is behaving the way that FEA said it should.
With Nick finally giving in to Dave, and moving over to the dark side of lateral symmetry, i'm not sure how us X2 fans will get our fix.
