Hello Ito,
1.  When the manufacturer is decided, I hope we get a new time estimate
for completion.  That is what I meant about having a revised expected
ship date by the end of the week.
2.  Yes, the new wing is heavier and that will reduce performance at
lower frequencies but performance will still be OK by specification.  As
you know, we had extra performance.  At 30Hertz and higher, the heavier
wing should actually have as good or better performance because much
energy was used to try control the old wing vibration.
3.  The new wing frequency for the old wing problem is now over 200
Hertz. For the new wing the first vibration mode of concern is actuator
bowstring at about 50 Hertz.
Regards- Omar
