my plane only fluttered on the fastst of passes and checks showed even after months of this no damage, i have also seen the milisecond buzz bang happen.
anytime i hear flutter i yank the throttle back and hard up at the same time, this dumps speed quicker than anything else. however if the plane can take it a little buzz every now and again winds up the old guys who start moaning
the buzz bomb however gets cheers for longer and longer flutters ( as it's pretty slow and takes a lot to start it off lol )
