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!!" ************************************** Get a sneak peak of the all-new AOL at http://discover.aol.com/memed/aolcom30tour ________________________________ Message 2 _____________________________________ Time: 09:29:23 AM PST US From: "steve korney" Subject: RE: Glasair-List: Re: Glasair-List Digest: 0 Msgs - 07/12/07 (snip) " I have performed high speed passes well in excess of 260 mph and haven't experienced flutter" Do ya think your RV-4 could have done 260 mph and not flutter...?

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. ************************************** Get a sneak peak of the all-new AOL at http://discover.aol.com/memed/aolcom30tour ________________________________ Message 4 _____________________________________ Time: 01:55:36 PM PST US From: "steve korney" Subject: Re: Glasair-List: Re: Glasair-List Digest: 0 Msgs - 07/12/07 "Although my plane burns 10 gallons per hour, I average close to 210 mph giving me 21 miles per gallon.
