Jon  My understanding is that the factory VNE was based on the fact that
that's as fast as they had tested it.  At that time smaller engines were the
norm and about 180KTS was the fastest the plane would go straight and level.
Mine can go about 218 straight and level and I have tested it to 230 KTS in
a full power dive.  I did experience flutter on my left rudder and had to
quickly pull up and pull power.  The flutter was violent and shook me up
quite a bit.  I was anxious to get on the ground because at the time I
didn't know what it was and didn't want to be in the air when something came
off.  A very hard landing with to much nose up allowed my prop to hit the
runway thus removing about a 1/2 inch.  I have since fixed the prop and
changed the incidence of my rudder with factory advice and have again tested
it to 230 KTS with no problem but now at about 215 to 230 kts my engine
starts running rough.  I have sought out lots of experts and no conclusions
to date.  I need to install a recordable engine monitor to diagnose the
problem but haven't had the time yet plus I'm a little gun shy about going
that fast .  Tim
