The Mistral Arrow's muffler was improvised by Power Flow and work
decently well but is and aesthetic catastrophe, I fully agree.  We are
working with the acoustical lab of the Swiss Intitute for Technology on
an in-cowl muffler, specifically tuned to dampen most effectively the
rotary's very narrowly defined fundamental frequency.  More on it at
Oshkosh next July.

Hi Francois,

I recall European requirements for quiet aircraft recently resulting in
some guys using similar long mufflers. Will yours meet these
requirements, or was I mis-informed ?

While leaving the Iranian revolution behind, in Jan of '80, we couldn't sell
the company's Beechcraft Queenair because it couldn't meet the European
noise requirements. Karibian
