Ernest,
   The pro= cedure is to test with many steps increasing speed in small increments alwa= ys ready
to reduce throttle a= nd increase AOA at the slightest in= dication of flutter..............

I think that is less of a factor in the RV world but a factor just the= same.
Flutter is really ugly.
How is the Vne testing= performed?  I can't think of anything other than pushing the throttle= to the firewall and waiting to see what happens, but that sounds awful dan= gerous to me.
