CEFOSKEY, you missed a trick here - just slow down the frame rate until the flight looks nice and controlled.
It may just be that this machine has a much snappier response rate than most helis, since most machines just ignore cyclic stirring. Possibly the gain factor on the control just needs to be reduced. Is this a force control sidestick or is there a reasonable amount of movement?
At this stage just some decent resolution photos would do me!
Showing engineers a low resolution blow up of what might be a helicopter doesn't do the X2 first flight justice...
