Two issues:

1) During cruise, the airspeed indicator sometimes drops to 000 for a few moments.  This causes FDC Live Cockpit to begin flaps deployment at cruise altitude and speed.

2) During taxi, the rudder seems to flutter back and forth and the aircraft sometimes responds sluggishly to rudder input.

I have tried reinstalling the aircraft, but the problems persist.  I have also searched this forum and the KB but didn't find anything applicable.

Thanks!
