I've been hearing people on this side of the pond saying they were seeing measurements all above 95 Db. Your plane must be a dream to fly in. I still have the original pictures that you sent me. Are the silencers still the same or did you have to modify them? I'd really like to see these. Do you have a sound clip taken during flight? It would be sweet music to ones ear to hear that.

If there's only a knot or two difference from typical numbers, I'd consider something like that myself, cuz I know how fatiguing high noise levels can be on long trips, not to mention annoying to everyone within any reasonable distance of the acft.

I'll need one about the end of November. I have a beautiful RV wing jig, made of welded structural steel, which has built numerous RVs I'll be finished with it about the end of November.
