After I assembled my rudder I ran a wire through the hinge to get some idea
how well it was balanced and found it not to be so good. One builder that
lived down the street made a plaster cast of the cavity and poured molten lead
to
get more weight in the counter balance cavity. Using the plans method, I
couldn't get in the required weight and I wasn't about to drill out the lead
shot. I have over 1,000 hours and as I mentioned before, I have performed high
speed passes well in excess of 260 mph and haven't experienced flutter.
At the time I had stopped constructing an RV 4 and decided to weight the
tail feathers and found the total weight of the RV 4 tail feathers almost
equaled the weight of my Glasair rudder!! I completed the very first 2S and
discovered that although I installed a 200 hp IO360, constant speed prop and all
weather instrument panel, my plane was not as nose heavy as I thought it
would be. The next to complete the 2S had an aft CG problem and that led
Stoddard Hamilton to advise moving the wing back and introducing the Super 2S
series. I thought; "How bazaar, why didn't they just offer the tail feathers and
control surfaces in carbon fiber!!"

Do ya think your RV-4 could have done 260 mph and not flutter...?

I never completed the RV 4 I was building, so I can't tell you if the rudder
would have fluttered at 260 MPH. I came close to that speed doing aerobatics
in one that a friend owned, but I wouldn't recommend approaching that speed
in one. Also, because of all the structural failures in RV's I never felt
comfortable in one. Second to RV structural failures are Lancairs. I have never
heard of a structural failure in any Glasair. Before building my Glasair I
owned an S1S Pitts with a souped up IO 360. I had that plane well over 200 mph
doing aerobatics and never experienced a flutter. Before owning both planes
I flew a T-18 and performed 230 mph runs with it. That plane didn't have a
counter weighted rudder.
I have flown my Glasair to 46 states, Canada and Mexico. The plane has a
ride like a Cadillac. I have flown in bad thunder storms, snow, ice and
freezing rain that was so bad, chunks of ice flew off the prop and cowling and
smash into the wind screen. And I have hand flown solid IFR for hours on end.
I
have had the plane close to 18,000 feet altitude and I find the plane stable
and as smooth as glass. And survivability in a crash is the best of all the
composites. My beef with Stoddard Hamilton was not offering parts or even the
whole kit in Carbon fiber. I always felt a carbon fiber version would shed
hundreds of pounds in weight and would open up a whole new market. Especially
if all the known speed modifications were introduced. Although my plane burns
10 gallons per hour, I average close to 210 mph giving me 21 miles per
gallon.

When you say that, is it at wide open throttle, 2700 rpm's and @ sea level /
standard day....or 18000 ft. or what...? I need more information...
