				John H., and others,
   
    John, a while back you asked about insulating material that you could install in
  your MkIII, to help reduce cabin noise.
    The last I heard, I think you said you found the material you wanted.
   
    I'm curious if you ever got around to installing this material, and if you've had a chance to go on a long enough flight to be able to judge how well it works.

  Haven't completed the  task.
   
  Flew to Lakeland without it, about 11  hours.  Could still hear, a little, when I got back to  Alabama.
   
  If I get energetic before time to go  to MV, I'll pull the center section and stick some insulation in there.  I  probably need to take the time to do that.  I also have a new set of Lord  Mounts for the engine.  The center section needs to be pulled to lift the  engine enough to do that job.
   
  Hopefully, I will get all enthused  and "get'er done".

				John,
   
    From the looks of all the thunderstorms headed our way, there ought to be lots of time for indoor projects.  : )
   
    I'm looking forward to a flight report!  If the improvements sound good, I'm close to a point where I could include them in my plane's completion.

  Removing the center section from my mkIII is a  major undertaking.  That is the only reason the insulation is not already  installed.  If I was in the building and completion phase, I'd already have  the insullation stuck in place.  No doubt that any insulation would be an  improvement in noise control in my mkIII.

				Just FYI, I saw this ad for sound insulating material recently.

				Also just FYI, I saw this 'new' prop at the AERO 2010 expo in Friedrichshafen in Southern Germany last month. It's called the QD2, a four bladed prop with a difference. That being that the two sets of two blades are both angularly and axially offset and that apparently reduces the noise signature and they also claim some performance improvements too. It's currently being test flown  on a trike.
 
 See this site. http://www.e-props.fr/EP_RD.html Info is about 2/3rds down the page.
 
 David.
